At the start of the week, you could run for 8 minutes. By the end of the week, you could run for 15 minutes. Which proportion could you use to find the percent increase in your running time?7/15=n/100

8/7=n/100

7/8=n/100

8/15=n/100

Answers

Answer 1
Answer: The formula for finding percent increase is:
(Final - Initial)/Final * 100 = n
Divide both sides by 100 and you get:
(final-initial)/Final = n/100
Plug in all the numbers, and you get:
(15-8)/15 = n/100, or
7/15 = n/100

Hope this helped!! :D

How tall is a triangle that is 10ft x 10 ft x 10ft?

Answers

Are you saying that all 3 sides of the triangle are equal, and are 10-ft each ?

In that case, if you set the triangle down on one of its sides,
the vertex at the top will be 5√3 = about 8.66-ft above the table.
Square root of 75 or 8.66 rounded. Use Pythagorean Theorem.

What’s the answer for 6x+7-4x=8+7x-26

Answers

Answer:

x=7

Step-by-step explanation:

Add common variables.

(6x-4x)+7= 8+7x-26

2x+7= 8+7x-26

Subtract the least variable to both sides.

2x+7= 8+7x-26

-2x          -2x

Now, simplify the equation.

7= (8-26)+5x

7= -18+5x

Add 18 to both sides.

7= -18+5x

+18 +18

Divide both sides by 5 to isolate the variable.

35= 5x
