J = 14
J = 1/2S + 4 1/2
14 = 1/2S + 9/2....multiply everything by 2 to get rid of fractions
28 = S + 9
28 - 9 = S
19 = S
check...
14 = 1/2S + 9/2......S = 19
14 = 1/2(19) + 9/2
14 = 9 1/2 + 9/2
14 = 19/2+ 9/2
14 = 28/2
14 = 14 (correct)
so the sister is 19 <===
Answer:

8a+5b-9
Answer:
65.9 so it rounds to 66cm
Answer:
OPS and TSP,
QPS and PSR
Step-by-step explanation:
The alternate interior angles look like the picture provided below. Next time, don't clickbait with the wrong amount of points.
QPS is included but isn't one of the answers because they it's not a multiple choice question.
If the two triangles are similar you can use a proportion to solve for the length of the legs.

=

Now, you would cross multiply to get
4x=18
Now, you simplify that using the division property of equality.
You end up with
x=4.5
Therefore, the legs of the triangle with a base of 9 inches will each be 4.5 units long.
