Answer:

Isolate.

Step-by-step explanation:

To solve a one-step equation, you must isolate the variable.

For example,

3x = 9.

You must isolate x, which just means you have to get x by itself.

Divide by 3 on both sides to get x by itself.

x = 3.

The answer to this question is isolate.

The length of a rectangle field if 7/5 of its width. if the perimeter of the field is 240 meters, what are the length and width

trasher [3.6K]

Perimeter of any figure is all its sides summed up

for a rectangle, with two equal pairs, that means, length + length + width + width or 2length + 2width, or 2(length + width)

but we know the length is 7/5 the width

width = w
perimeter = P

$\bf P=2\left(\frac{7}{5}w +w \right)\qquad P=240\implies 240=2\left(\frac{7}{5}w +w \right)
\\\\\\
120=\frac{7}{5}w +w\impliedby \textit{let's multiply both sides by 5}
\\\\\\
600=7w+5w\implies 600=12w\implies \cfrac{600}{12}=w$

and the length is 7/5 of that
