Five star farm purchased 2400 apple trees. if 80 trees can be planted on each acre of land, how many acres will be needed to plant all the trees?

1 acre = 80 trees

x acres = 2400 trees

x = (2400*1)/80 = 2400/80 = 30 acres

5x+2x=49

7x=49

x=7. 35 apples

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°
