7) a=70°
b=140°
8) a=74°
b=106°
c=41°
d=115°
2 1/2 yds = 2.5 x 36 = 90 inches...what she started with
2 ft 8 in = 2(12) + 8 = 32 inches...what she had left
90 - x = 32
90 - 32 = x
x = 58 inches....so she used 58 inches
Answer: First Choice. no solution
Step-by-step explanation:
<u>Given</u>
5 (x + 1) ≤ 5x + 3
<u>Expand parentheses and apply the distributive property</u>
5x + 5 ≤ 5x + 3
<u>Subtract 5x on both sides</u>
5x + 5 - 5x ≤ 5x + 3 - 5x
5 ≤ 3
5 ≤ 3 is not true, therefore, there is <u>no solution</u>.
Hope this helps!! :)

Those are not equivalent.
If the difference is a constant, the difference is : (60-18)/(11-4)=42/7=6
