If 1/4 of a gallon of paint covers 1/3 of a fence ,how much paint is needed for the entire fence?

3/4 gallon

Step-by-step explanation:

Write and solve an equation of ratios:

1/4 gallon       1/3 fence

=

        x              1 whole fence

Then (1/4)(1) = (1/3)(x).  Multiplying both sides by 3 to isolate (solve for) x, we get:

3/4 gallon = x = the amount of paint needed to cover the entire fence

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°
