Question

A glass is 1/2 full. Then 65cm^3 of orange juice is poured in. The glass is now 6/7 full. What is the total volume of the glass?

Answer 1

Answer:

182 cm³

Step-by-step explanation:

Let x cm³ be the total volume of the glass.

1/2 x + 65 = 6/7 x

by multiplying both sides by 2, we have

x + 130 = 12/7 x

5/7 x = 130

x = 182
