2.5x + 8.5y=90 what is the number for x

It will have infinitely many solutions depending upon value of y.

For eg:

Put y=10,

2.5x+8.5×10=90

2.5x=5

x=2

For y=0

x=90/2.5=36

and so on

You need a system of linear equations to get a single solution for x

i can you with this question sweetie!

step-by-step explanation:

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
