Which equation represents the total price (p) paid when buying books (b) that cost $3.99 each? how much do 13 books cost?

a. b = 3.99p; $51.87
b. b = 3.99c, $51.87
c. p = 3.99b; $0.31
d. p = 3.99b; $51.87

Your answer is D p=3.99;$51.87

Step-by-step explanation:

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°

(8+64)^2= 5184 < answer

step-by-step explanation:

2^3 = 8

4^3= 64

(8+64)^2 = 5184
