Find the percent of change. Round your answer to the nearest tenth of a percent, if
kozerog [31]

Answer: a. 14% decrease or 86% of the whole

B. 137.5% increase

Step-by-step explanation:

A. Divide new price by old price and you get .86, change that to a percent by multiplying by 100. That equals 86%, the percent of change would be the difference of 100% to 86%, which is 14%

B. Use above explanation but don’t find the difference. 77/56= 1.375, 1.375*100=137.5

Can someone teach me how to balance algebra equations, I just don't get how to do it. Like with fractions?
natka813 [3]

Answer:

<h3>Move all the x terms to one side. Use inverse operations and add 1 5 x 15x 15x to both sides to keep the equation balanced. Solve by working backwards from the order of operations. This means we need to undo the −2 first by adding 2 to both sides of the equation to keep it balanced.</h3>

adell [148]
I saw the image. It formed 2 right triangles. 1 small and 1 big.
small triangle has a long leg of 4 feet and hypotenuse of 6 feet.
big triangle has a long leg of (x) and hypotenuse of 6 + 12 ft.

proportion:

4/6 = x / 18
4 * 18 = 6x
72 = 6x
72/6  = x
12 = x

The distance from the base of the stairs to the tallest column is 12 feet.
