George has 4 times as many books as Grace and 3 bookshelves. He has 203 books and bookshelves all together. How many books does Grace have?

A 4(x + 3) = 203

B 203 = 3(x + 4)

C 203 = 4x + 3

D 3x + 4 = 203

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

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°

c
