What fraction is located at point a on the number line

1 1/2

Step-by-step explanation:

Since there are 4 tics between 1 and 2 (including the tic on 2), we can assume that the number line is split into 1/4 (quarters). Therefore, each tic is 1/4 higher than the last. The tic after 1 is 1 1/4, the next is 1 2/4, the next is 1 3/4, and the last shown is 1 4/4 (which is rewritten as 2). The tic marked is at 1 2/4, which can be simplified to 1 1/2.

answer: sine

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°
