1 answer:
Nataliya [291]3 years ago
4 0

Answer:

y = 5

Step-by-step explanation:

22.5(10-y)+27.5y=250

225 - 22.5y + 27.5y = 250\\\\

Combind like terms,

225 + 5y = 250

Subtract 225 from both equations to isolate the variable.

5y = 25

Divide both sides by 5 to isolate the variable and solve it.

y = 5

Marysya12 [62]

Answer:

Option C)1 in. = 6 ft

Step-by-step explanation:

Up to know we have the following equality:

45 f = 7 1/2 in

Or what is the same that:

45 f = 7.5 in

If we divide both sides of the equation by 7.5 we will get the equivalence to 1 inch:

45/7.5 f = 7.5/7.5 in

6 = 1 in

So, the correct answer if option C)1 in. = 6 ft
