solve the equation -t = 9(t-10)−t=9(t−10)
Answer:
Infinitely many solutions.
Step-by-step explanation:
-t=9(t-10)-t=9(t-10)
-t=9t-90-t=9t-90
-t=8t-90=9t-90
8t-(-t)-90=9t-90
8t+t-90=9t-90
9t-90=9t-90
Answer:
If you mean −t=9(t−10), then the answer is 9, if you mean −t=9(t−10)−t=9(t−10) then infinite solutions.
Step-by-step explanation:
Here is the answer if you mean −t=9(t−10):
−t = 9 (t−10)
Simplify the equation.
-t = (9)(t) + (9)(-10)
-t = 9t + -90 (Add the opposite)
-t = 9t - 90
Subtract -9t
-t -9t = 9t - 90 - 9t
-10t = - 90
Divide -10 on both sides to make sure the equation is balanced on both sides. And to isolate t to get the final answer.
-10t = -90
-10t = -10
Therefore,
t = 9Is the final answer.
I Hope this helps! Have a great rest of your morning, afternoon, or evening! :D

I need help this is due this Wednesday on my college math class! ASAP!!! This needs to be shown full work for full credit!!
Answer:
is it 8 apples to her mother or 10 since I had this exact problem?
Step-by-step explanation:
Ashe started with 32 apples in the basket initially.
How to find half of something ?To find the half of something just multiply 1/2 with the given value.
According to the given question Linda picked a basket of apples.
Assuming she had x apples initially.
She gave half of the apples to the neighbour,Therefore she now has (x - 1/2x) apples which is = 1/2x apples.
Then she gave 10 to her mother,So the remaining apples she has now is
= ( 1/2x - 10 ) apples
= (x - 20)/2.
Then she gave half of the apples to her best friend so the no. of apples she has now is (x - 20)/2×1/2 which is = (x - 20)/4 and she kept the remaining 3.
∴ (x - 20)/4 = 3
x - 20 = 12
x =32.

Brook rode her bike 7 miles in 30 minutes. Joshua rode his bike 25 miles in 2 hours. which one is faster. HEEEEEEELLLLLLLLLLLLLLPPPPPPPPP
Answer:
Brook is faster.
Step-by-step explanation:
1 hour=60 minutes
2 hours=2*60=120 minutes
-------------
7 miles in 30 minutes vs 25 miles in 120 minutes
7/30=0.233...mile per minute
25/120=0.20833...mile per minute
Brook is faster than Joshua.
Explanation:To determine which person is faster, we can compare their average speeds.
Average speed is calculated by dividing the total distance traveled by the total time taken.
For Brook, she traveled 7 miles in 30 minutes, so her average speed is:
7 miles ÷ 30 minutes = 0.2333 miles per minute.
For Joshua, he traveled 25 miles in 2 hours, which is equivalent to 120 minutes. So his average speed is:
25 miles ÷ 120 minutes = 0.2083 miles per minute.
Therefore, Brook is faster than Joshua as her average speed is higher.
The isosceles trapezoid is part of an
isosceles triangle with a 46° vertex angle.
Enter the measure of an acute base angle of
the trapezoid.
Final answer:
Using the properties of isosceles triangles, the acute base angle of the isosceles trapezoid, which is part of an isosceles triangle with a 46° vertex angle, is found to be 67°.
Explanation:
To find the measure of an acute base angle of the isosceles trapezoid that is part of an isosceles triangle with a 46° vertex angle, we can apply the properties of isosceles triangles. By the Isosceles Triangle Theorem, we know that the angles opposite the equal sides are equal.
Since the given triangle is isosceles, the two base angles must also be equal. Additionally, we know that the sum of all angles in any triangle is 180°.
Let's call each of the base angles B. Then, the sum of all angles in the triangle is:
46° + B + B = 180°
Now we solve for B:
2B = 180° - 46° = 134°
B = 134° / 2 = 67°
Thus, each base angle of the isosceles triangle is 67°. Next, considering the isosceles trapezoid, we know the adjacent angles must be supplementary because they are on the same line. This means that one base angle of the isosceles trapezoid equals:
180° - 67° = 113°
However, since the student is looking for the measure of an acute base angle of the trapezoid and 113° is an obtuse angle, the acute base angle is the original 67° angle that we found. This is because the acute and obtuse angles in the trapezoid are adjacent angles around the same vertex, and the acute angle is the angle that's interior to the triangle.
Therefore, the measure of an acute base angle of the trapezoid is 67°.

Raise the fraction to the highest term 1/5 to 15ths=
Final answer:
To raise the fraction 1/5 to 15ths, multiply both the numerator and the denominator by 3 to get the equivalent fraction 3/15.
Explanation:
To raise the fraction 1/5 to 15ths, we need to find an equivalent fraction that has a denominator of 15. To do this, we need to find a number that we can multiply both the numerator and the denominator of 1/5 by to get a new fraction with a denominator of 15. Since 5 multiplied by 3 equals 15, we multiply both the numerator and the denominator of 1/5 by 3.
Thus, we have:
1/5 × 3/3 = 3/15
To raise the fraction 1/5 to 15ths, multiply both the numerator and the denominator by 3 to get the equivalent fraction 3/15.
The fraction 1/5 is equivalent to 3/15 when raised to 15ths.

The sum of Ava’s and Grace’s age is 35. Ava is one year less than three times Grace’s age. How old is Grace?
Grace is 9 years old. We found this by setting up a system of equations with the information given and solving for Grace's age.
Explanation:We are given two pieces of information about Ava and Grace's ages:
The sum of Ava’s and Grace’s age is 35.Ava is one year less than three times Grace’s age.To find Grace’s age, we can set up a system of equations based on the information provided:
Let G represent Grace’s age.Let A represent Ava’s age.The first equation can be written as:
A + G = 35
From the second piece of information, we can write:
A = 3G - 1
Now, we can substitute the expression for A into the first equation:
3G - 1 + G = 35
Combine like terms:
4G - 1 = 35
Add 1 to both sides:
4G = 36
Divide by 4:
G = 9
So, Grace is 9 years old.

[tex]10.99D \leq 90.01[/tex]
and
[tex]10.99D + 9.99 \leq 100[/tex]
Step-by-step explanation:
1.
The equation to solve is:
[tex]Ax+4Ax=51+2Ax[/tex]
The variable is "x", so we take all the terms with x's and take the number to one side. Then we add up the like terms of x's and solve for x. Shown below:
[tex]Ax+4Ax=51+2Ax\\Ax+4Ax-2Ax=51\\x(A+4A-2A)=51\\x(3A)=51\\x=\frac{51}{3A}\\x=\frac{17}{A}[/tex]
x = 17/A
Correct answer is A
2.
The equation is:
[tex]10y=3x-11[/tex]
The point that would lie on the graph is the point when put, makes the equation true. So we check each point and see if the equation holds:
[tex]10y=3x-11\\10(0.5)=3(2)-11\\5\neq -5[/tex]
first point doesn't lie on the graph.
[tex]10y=3x-11\\10(1)=3(4)-11\\10 \neq 1[/tex]
second point doesn't lie on the graph.
[tex]10y=3x-11\\10(0.7)=3(6)-11\\7=7[/tex]
This point lies on the graph. So, this is the answer.
Correct answer is (6, 0.7)

Let Miguel buy D DVDs. Each costing 10.99, that would make the cost:
10.99D
Shipping cost entire order is 9.99, so this would be added to DVD cost. Total cost:
10.99D + 9.99
This total cost can be NO MORE THAN 100, so this expression would be equal to or less than 100, so we can write:
[tex]10.99D + 9.99 \leq 100[/tex]
If we take 9.99 to the right side and subtract, it becomes:
[tex]10.99D \leq 90.01[/tex]
First choice is correct.
Second choice, clearly, isn't correct.
Third choice, similarly, isn't correct as well.
Fourth choice, because of "+" sign on right side (of 9.99) is also incorrect.
Fifth choice is what we initially got, so this is correct.
First and Fifth Choice is right.
A truck carries apples, grapes, and blackberries in the ratio of 4:3:4 if the apple weighs 160 pounds how much does the truckload of fruit weigh in total
Answer:
160/x = 4/3
x = (160/4)(3) = 40(3) = 120
Apples: 160 pounds
Grapes: 120 pounds
Blackberries: 160 pounds
The total weight of this truckload of fruit is 160 + 120 + 160 = 440 pounds.
To find the total weight of the truckload of fruit with apples weighing 160 pounds in a ratio of 4:3:4, calculate the total ratio parts and apply it to the weight of apples. The total weight of the fruit is 440 pounds.
Explanation:The truck carries apples, grapes, and blackberries in the ratio of 4:3:4.
To find the total weight, you need to calculate the total ratio parts, which is 4 + 3 + 4 = 11 parts. Then, for apples alone, 4 parts represent 160 pounds, so each part is 160/4 = 40 pounds. The total weight of the truckload of fruit would be 11 parts * 40 pounds = 440 pounds.

At the start of the month, Jodie had sold 885 copies of her new book. At the end of the month, she had sold 1,364 copies of her book. If each book profits $13.97, approximately how much did the book profit in the entire month?
Approximately $ 31419 profit is earned from selling books in entire month
Solution:
Given that Jodie had sold 885 copies of her new book
At the end of the month, she had sold 1,364 copies of her book
We have to determine the profit earned in the entire month
From given information,
Start of month sale = 885 copies
End of month sale = 1364 copies
Total copies of books sold = Start of month sold + end of month sold
Total copies of books sold = 885 + 1364 = 2249
Also given that each book profit is $ 13.97
Profit of 1 book = $ 13.97
Therefore for 2249 books, profit earned is given as:
Profit of 2249 books = $ 13.97 x 2249 = 31418.53
Therefore approximately $ 31419 profit is earned from selling books in entire month

A square has an area of 44.89 inches squared. How do I get the length of the diagonal?
Answer:
6.7√2 in ≈ 9.48 in
Step-by-step explanation:
First, use the area of the square to find the side length.
A = s²
44.89 in² = s²
s = 6.7 in
The diagonal of a square divides it into 45-45-90 triangles. You can use Pythagorean theorem to find the length of the diagonal.
c² = a² + b²
c² = (6.7 in)² + (6.7 in)²
c = 6.7√2 in
c ≈ 9.48 in
Answer: 6.7√2
Step-by-step explanation: Let's start this problem by drawing a picture of a square with a diagonal of length x.
Now to find the length of the diagonal, let's first find the length of a side of the square. To find the length of a side, remember that the formula for the area of a square is S² and since we know that the area of the given square is 44.89 inches, we can set up the equation 44.89 = S².
Square rooting both sides, we have 6.7 = S so we can give the side of our square a length of 6.7. Now to find the value of x, it's important to understand that the diagonal of a square creates 45° 45° 90° triangles and in a 45° 45° 90° triangle, the hypotenuse = √2 × leg.
So we have x = 6.7√2.
So the length of the diagonal of the square is 6.7√2 inches.

four slices of pizza x price of 1 slice of pizza + one bottles of water x price of 1 bottle of water = $ 8.25
[tex]4 \times p + 1 \times b = 8.25[/tex]
4p + b = 8.25 ---- eqn 2
Let us solve eqn 1 and eqn 2 to find values of "p" and "b"
Multiply eqn 2 by 2
8p + 2b = 16.5 --- eqn 3
Subtract eqn 1 from eqn 3
8p + 2b = 16.5
2p + 2b = 7.25
(-) ----------------------
6p = 9.25
p = 1.542From eqn 1,
2p + 2b = 7.25
2(1.542) + 2b = 7.25
2b = 4.166
b = 2.083Thus price of 1 slice of pizza is $ 1.542 and price of 1 bottle of water is $ 2.083
