Twice a number is 24 less than 4 times the number find the number
The question asks for a number which when multiplied by 2 gives a result that is 24 less than the result of the number when multiplied by 4. The solution to this problem is the number 12.
Explanation:The student's question asks about algebraic expression and solving for a value. This could be written as an equation:
2x = 4x - 24
First, let's simplify this equation by subtracting 2x from both sides, this gives you:
2x = 24
Then, solve the equation by dividing both sides by 2, and we find that the number is:
x = 12
So, the number that the student is searching for is 12. Twice this number is 24, which is indeed 24 less than 4 times the number (48).

A bicyclist traveled with a speed of 12 km/h from a camping ground to a station, located 60 km away. Write a formula expressing the dependence of the variable s on t, where s is the distance between the bicyclist and the station in km, t - the duration (time) of his travel in hours. Using the formula, find:
Answer:
s=18
Step-by-step explanation:
First of all, the formula is s=60-12t. thanks to the person who answered this question first (teehee)
S=distance and t=duration.
We also know that the distance is 60 km, the bicyclists's speed is 12 km/h, and the duration for this example is 3.5 hours.
So, using the formula, we substitute all the variables and s=18.
Thanks!

The half-life of a substance is how long it takes for half of the substance to decay or become harmless (for certain radioactive materials). The half-life of a substance is 8.6 days and there is an amount equal to 15 grams now. What is the expression for the amount A(t) that remains after t days, and what is the amount of the substance remaining (rounded to the nearest tenth) after 37 days? Hint: The exponential equation for half-life is A(t) = A0(0.5)t/H, where A(t) is the final amount remaining, A0 is the initial amount, t is time, and H is the half-life.
Final answer:
The amount of a substance remaining after a period of time can be calculated using the half-life formula A(t) = [tex]\frac{A0(0.5)t}{H}[/tex]. After 37 days, with a half-life of 8.6 days starting with 15 grams, approximately 2.2 grams will remain.
Explanation:
The half-life of a substance is the amount of time it takes for half of the substance to decay. For a substance with a given initial amount, the expression for the amount A(t) that remains after t days is A(t) = [tex]\frac{A0(0.5)t}{H}[/tex], where A0 is the initial amount, t is the time in days, and H is the half-life.
Given that the half-life H is 8.6 days and the introductory sum A0 is 15 grams, able to utilize this condition to discover the remaining sum after a certain number of days. To decide the sum of the substance remaining after 37 days, we substitute these values into the equation: A(37) = [tex]\frac{15(0.5)37}{8.6}[/tex]
Calculating this expression, we get that approximately 2.2 grams remain after 37 days, rounded to the nearest tenth.

Determine the value of y in the equation: -5y-9=-(y-1) (show all work)
The value of y in the equation is -2.5.
Explanation:To determine the value of y in the equation -5y-9=-(y-1), we can start by distributing the negative sign to both terms within the parentheses. This gives us -5y-9=-y+1. Next, we can combine like terms by adding y to both sides of the equation. This simplifies the equation to -4y-9=1. To isolate y, we can subtract 9 from both sides of the equation, resulting in -4y=10. Finally, we divide both sides of the equation by -4 to find the value of y, which is -2.5.
An artist is creating a sculpture using bendable metal rods of equal length. One rod is formed into the shape of a square and another rod into the shape of an equilateral triangle. If each side of the triangle is 2 inches longer than each side of the square, how long, in inches, is each rod?
Answer:
24 inches
Step-by-step explanation:
We are given that an artist creating a sculpture using bendable metal rods of equal length.
One rod is in square shape and second rod is in equilateral triangle shape.
We have to find the length of each rod
Let side of square= x inches
Length of each side of equilateral triangle =x+2 inches
We know that perimeter of square=[tex]4\times side[/tex]
Perimeter of equilateral triangle=[tex]3\times side[/tex]
Using the above formula
Then , Length of square shaped rod=perimeter of square =[tex]4x[/tex]
Perimeter of equilateral triangle =Length of equilateral shaped rod=[tex]3(x+2)[/tex]
Length of square shaped rod=Length of equilateral triangle shaped rod
[tex]4x=3(x+2)[/tex]
[tex]4x=3x+6[/tex]
[tex]4x-3x=6[/tex]
[tex]x=6[/tex]
Length of each side of square =6 inches
Length of square shaped rod=[tex]4\times 6=24 inches[/tex]
Length of each side of equilateral side=6+2=8 inches
Length of equilateral shaped rod=[tex]8\times 3=24 inches[/tex]

Livia’s bill for lunch came to $8 before tax and tip. The restaurant included a 7 percent sales tax, and she left a 15 percent tip, which she calculated on the bill before the sales tax was added. What was the total cost of Livia’s lunch?
$8.56
$8.68
$9.20
$9.76
HELPPPPPP PLZZZ
Answer:
Total cost $9.76 of Livia's lunch.
Step-by-step explanation:
Livia's bill for lunch came = $8.00
The restaurant included a 7% sales tax = 7% of $8.00
= 0.07 × 8 = 0.56
She left a tip of 15% = 15% of $8 =
= 0.15 × 8 = $1.20
Now add tip and tax to the lunch bill
Bill (Pre tax) = $8.00
Tax 7% = $0.56
Tip 15% = $1.20
= 8.00 + 0.56 + 1.20 = $9.76
Total cost of Livia's lunch was $9.76
Find two consecutive even integers such that five times the smaller integer is ten more than three times the larger integer.
The problem can be solved by setting up and solving an algebraic equation based on the given conditions. With 'x' representing the smaller integer, and 'x + 2' for the next consecutive even integer, 'x' can be found to identify these integers.
Explanation:To find the two consecutive even integers specified in the question, we should first assign variables to these numbers. Let's say the smaller even integer is 'x', then the next consecutive even integer will be 'x+2' (because even numbers increment by 2).
According to the problem, five times the smaller integer equals ten more than three times the larger integer. We can translate this into a mathematical equation: 5*x = 3*(x+2) + 10.
By simplifying this equation through multiplication and subtraction, we can make 'x' the subject to find the value of the smaller even integer. The larger integer is then x + 2. Using these formulas, we can identify the two consecutive integers that meet the criteria specified in the problem.

What else would need to be congruent to show that triangle ABC is congruent to triangle DEF by ASA?
Answer:
Option D. ∠B ≅ ∠E
Step-by-step explanation:
In ΔABC and ΔDEF,
Measure of side AB = Measure of side DE = 10 units
∠A ≅ ∠ D ≅ 45°
Now we have to prove ΔABC ≅ ΔDEF by the property of congruence ASA.
Since one angle and one side are equal.
So other angle based on sides AB and DE will be the adjacent angles ∠B and ∠E
Therefore, Option D. ∠B ≅ ∠E will be the answer.

What type of math is adding subtracting of positive and negative numbers
Final answer:
Adding and subtracting positive and negative numbers falls under the subject of arithmetic in mathematics. The rules for addition and subtraction of integers depend on the signs of the numbers being operated on.
Explanation:
In mathematics, adding and subtracting positive and negative numbers falls under the subject of arithmetic. This concept is also known as integer addition and subtraction.
When you add two positive numbers, the answer is positive. When you add two negative numbers, the answer is negative. When you add numbers with different signs, you subtract the smaller absolute value from the larger one and take the sign of the number with the larger absolute value.
Similarly, when you subtract a positive number from another positive number, or a negative number from another negative number, you follow the same rules. However, when you subtract a negative number from a positive number, you can think of it as adding a positive number, resulting in a larger positive number.
