Use tape diagrams to calculate the solution of 30 = 5w. then, check your answer.

6

Step-by-step explanation:

if 30 = 5w

then 30/5=w=6

-tape diagrams in picture-

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
