B) 25

Step-by-step explanation:

0.10x + 0.20y = 0.18(x+y)

Here, y=100

Put the value of y in the given equation,

0.10x + 0.20*(100) = 0.18(x+100)

0.10x + 20 = 0.18x + 18

Subtract 0.18x and 20 on both sides,

0.10x - 0.18x = 18 - 20

-0.08x = -2

Divide by -0.08,

x = 25 millilitres

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°
