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
Answer:
Eight times the sum of a number and 2 is equal to 7.
times = multiply
sum = ()
and = +
SO..
8(w + 2 ) = 7
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>
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.
