What does this simplify to? 3+5.25 = 1 - 2.8x
Answer:
-2.59 = x
Step-by-step explanation:
3+5.25 = 1 - 2.8x
Combine like terms
8.25 = 1-2.8x
Subtract 1 from each side
8.25 -1 = 1-1-2.8x
7.25 = -2.8x
Divide each side by -2.8
7.25/-2.8 = -2.8x/-2.8
-2.589285714 = x

there are 75 students in a speech contest. Yesterday, 1/3 of them gave their speeches. Today, 2/5 of the remaining students gave their speeches. how many students still haven't given their speeches?
Answer:
30 students
Step-by-step explanation:
Yesterday: 1/3 of the 75 students (75 / 3) = 25 students
There are now 50 students remaining to give their speeches.
Today: 2/5 of the 50 students (50 / 5 = 10 x 2 ) = 20 students
50 - 20 = 30 students remaining to give their speeches.
Therefore, 30 students still haven't given their speeches.
To find out how many students still haven't given their speeches, we first need to calculate the number of students who gave their speeches yesterday and today. Since there were 75 students in total and 1/3 of them gave their speeches yesterday, we multiply 75 by 1/3:
75 * 1/3 = 25 students
This means that 25 students gave their speeches yesterday. To find out how many students were left for today, we subtract the number of students who gave speeches yesterday from the total number:
75 - 25 = 50 students remained
Today, 2/5 of the remaining students gave their speeches. We calculate this by multiplying the number of remaining students by 2/5:
50 * 2/5 = 20 students
Therefore, 20 students gave their speeches today. Now, we subtract the number of students who have given their speeches today from the remaining number of students to find out how many have not given their speeches yet:
50 - 20 = 30 students
Thus, 30 students still haven't given their speeches.

Two angles form a linear pair. The measure of one angle is 2/3 the measure of the other angle. Find the measure of each angle
Answer:
108° and 72°
Step-by-step explanation:
let one angle be x then the other angle is [tex]\frac{2}{3}[/tex] x
the sum of the 2 angles = 180°, hence
x + [tex]\frac{2}{3}[/tex] x = 180 ( combining the left side )
[tex]\frac{5}{3}[/tex] x = 180
multiply both sides by 3 then divide both sides by 5
5x = 540 ⇒ x = 108
the 2 angles are x = 108° and [tex]\frac{2}{3}[/tex] x = 72°

Haruka hiked several kilometers in the morning. She hiked only 6 kilometers in the afternoon, which was 25% less than she had hiked in the morning.
Haruka hiked 8 kilometers in the morning. This is calculated by recognizing that the 6 kilometers she hiked in the afternoon was 25% less than her morning hike, making it 75% of her morning hike.
Explanation:Haruka hiked several kilometers in the morning. She hiked only 6 kilometers in the afternoon, which was 25% less than she had hiked in the morning. To solve this problem, let's represent the number of kilometers Haruka hiked in the morning as x.
Since the afternoon hike was 25% less than the morning hike, this means she hiked 75% of the distance she did in the morning in the afternoon. The 6 kilometers she hiked in the afternoon then represent this 75% of the morning hike.
We can set up the equation as follows: 0.75x = 6. To find x, we divide both sides of the equation by 0.75. So, x = 6 / 0.75 which simplifies to x = 8.
Therefore, Haruka hiked 8 kilometers in the morning.
Use the function rule. Find y for x = 0, 1, 2, and 3.
y = 4x – 2
y = –2, 2, 6, 10
y = 2, 6, 10, 14

Which of the following equations represents a quadratic function?
Answer:
The correct options should be B and C.
Step-by-step explanation:
Quadratic equation is an equation in which the highest degree of the variable is 2. No fractional power of variable is acceptable in the equation. So, the power of variable can be 0, 1, and 2 only.
The given equations are,
[tex]y=-x^2+5\sqrt{x}-16\\y=2x^2-12x+9\\x=2y^2-9y+4\\5x-3y=-6[/tex]
From the above equations, equation 1, 2, and 3 has degree 2. But in equation 1, the power of variable x is 0.5 which is a fraction.
So, equation 2 and 3 only are the quadratic equations.
Therefore, the correct options should be B and C.

A bookstore is having a sale in which you can get 4 notebooks for $7.00 and 10 folders for 2.50. How much will it cost Rico to buy 5 notebooks and 6 folders
Step-by-step explanation:
First, you divide the money by how many notebooks/folders you can get.
Folders: $2.50 / 10 = $0.25
Notebook: $7.00 / 4 = $1.75
Now, you just multiply the notebooks and folders.
6 folders x $0.25 = $1.50
5 notebooks x $1.75 = $8.75
$1.50 + $8.75 = $10.25
Answer: $10.25
To calculate the cost for 5 notebooks and 6 folders with given sale prices, first find the unit price of each item, then multiply by the desired quantity and add the totals to get the final cost, which is $10.25.
The cost for 4 notebooks is $7.00, which means one notebook costs $1.75 (since $7.00 divided by 4 equals $1.75). To find the cost of 5 notebooks, we multiply 5 by $1.75 to get $8.75.
The cost for 10 folders is $2.50, which means one folder costs $0.25 (since $2.50 divided by 10 equals $0.25).
To find the cost of 6 folders, we multiply 6 by $0.25 to get $1.50.
Finally, we add these two amounts together to find the total cost: $8.75 (for notebooks) + $1.50 (for folders) equals $10.25, which is the total amount Rico will spend.
the area of a rectangular dog pen is 8 1/2 square feet. if the width is 3 2/5 feet, what is the length, in feet?
Answer:
Area of rectangle is equal to multiply the length by width
i.e [tex]A = l\times w[/tex] .....[1]
where
A is the area of rectangle ,
l is the length and
w is the width of the rectangle respectively.
Given : Area of rectangular do pen(A) = [tex]8\frac{1}{2} = \frac{17}{2}[/tex] square feet and width(w) = [tex]3\frac{2}{5} = \frac{17}{5}[/tex] feet.
To calculate the length in feet.
Substitute the given values in [1], we get
[tex]\frac{17}{2}= l\times \frac{17}{5}[/tex]
Multiply both sides by [tex]\frac{5}{17}[/tex] we get;
[tex]l = \frac{17}{2} \times \frac{5}{17} =\frac{5}{2} = 2\frac{1}{2}[/tex] feet.
Therefore, the length in feet is, [tex]2\frac{1}{2}[/tex]

what is the slope of a line perpendicular to the line of y=-1/4x-1
Answer: 4
The given line has a slope of -1/4 as this is the number in front of the x. The general equation y = mx+b has m as the slope. So m = -1/4 is given
Flip the sign to get -1/4 turn into +1/4 or just 1/4
Then flip the fraction (aka reciprocal) to go from 1/4 to 4/1 and that simplifies to 4.
Multiplying the original slope (-1/4) and the perpendicular slope (4) will result in -1.

Answers:
Problem 1) ASA
Problem 2) ASA
Problem 3) AAS
Problem 4) Neither
Problem 5) AAS
Problem 6) Neither
==============================
Explanation:
Any time we have ASA is when we can match up two pairs of angles and a pair of sides between the two pairs of angles. With problems 1 and 2, this happens. The corresponding angles that are congruent are the ones that have the same angle markers.
AAS is slightly different from ASA in that the side is not between the angles. This happens with problem 3 and problem 5. For problem 3, for instance, the second pair of angles are the two vertical angles. These angles are not marked, but they are congruent due to the vertical angle theorem. The same thing can be said about problem 5 as well.
With problem 4 and problem 6, we don't have any information about any pairs of angles, so we can't use AAS or ASA at all. We don't know if the triangles are congruent or not. They might be, but we simply don't have enough info to say either way.

Why is partitioning a directed line segment into a ratio of 1:3 not the same as finding the length of the directed line segment?
The ratio given is part to whole, but fractions compare part to part.
The ratio given is part to part. The total number of parts in the whole is 3 – 1 = 2.
The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4.
The ratio given is part to whole, but the associated fraction is .
Answer:
The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4.
Step-by-step explanation:
We know that partitioning a directed line segment into a ratio of 1:3 means that we are dividing the given line segment into two parts whose first part is 1 times the of some quantity while the another part is 3 times of the same quantity. So basically we are comparing part to part in by ratio. And total number of parts in the whole will be just sum of both so we get 1+3=4
Hence choice (3) is correct answer.
"The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4."
Final answer:
Partitioning a directed line segment into a ratio of 1:3 is not the same as finding the length of the directed line segment. The ratio compares parts within the whole, while finding the length involves measuring the entire segment. To find the length of each part in a 1:3 ratio, divide the length of the segment by 4.
Explanation:
Partitioning a directed line segment into a ratio of 1:3 is not the same as finding the length of the directed line segment because the ratio given is part to whole, while finding the length involves determining the actual measurement of the segment. The ratio 1:3 compares the parts within the whole, while finding the length of the segment involves measuring the entire length.
When the ratio is given as 1:3, it means that the segment is divided into 4 equal parts (1 part + 3 parts). The length of the entire segment is the sum of these 4 parts. To find the length of each part, you can divide the length of the segment by 4.
For example, if the length of the segment is 8 units, each part will have a length of 8/4 = 2 units.
