Can someone explain the full answers

A) 2x+5=9 then if x=1

2+5=9 which is wrong then A is wrong

B) x=2

2×2+5=9

4+5=9

then B is correct

C) x=3

2×3+5=9

6+5=9

then C is wrong

D) 2x+5<9

2×1+5<9

2+5<9

7<9

D is correct

E)x=2

2×2+5<9

4+5<9

9<9

E is wrong

F) x=3

2×3+5<9

6+5<9

11<9

F is wrong

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

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°
