Of the 140 7th graders, 15% earn the Presidential Physical Fitness award. How many students earn the award? *

21 students

Step-by-step explanation:

the percent proportion is a/w = p/100

where A is a part of the whole W, and p% or p/100 is the percent

a/140 = 15/100 (Substitute w =140 and p= 15)

a times 100=140 times 15 (cross poducts property)

100a=2100  (Multiply)

100a/100 = 2100/100 (divide both sides by 100)

a = 21 (simplify)

So, 21 students win the award.

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°
