0.2y - 0.5 = 3.5
what’s the equation

y =20

Step-by-step explanation:

0.2y - 0.5 = 3.5

Add .5 from each side

0.2y - 0.5+.5 = 3.5+.5

.2y = 4

Divide each side by .2

.2y/.2 = 4/.2

y = 20

if x = 1, then the answer is 3.5

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
