A glass is 1/3 full. Then 40cm3 of orange juice is poured in. The glass is now 5/7 full. What is the total volume of the glass?

105cm3

Step-by-step explanation:

subtract 5/7- 1/3

8/21=40cm3

21/21=105cm3=total volume

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
