Answer:
FG=17/4
Step-by-step explanation:
EF+FG=EG
3+x+3=5x+1
x+6=5x+1
6-1=5x-x
4x=5
x=5/4
FG=x+3
FG=5/4 +3
= (5+12)/4
FG=17/4 or 4 1/4 or 4.25
Let x = number of problems on test
If he got 14 wrong, then x - 14 is the number correct.

x - 14 = .72x
.28x - 14 = 0
.28x = 14
x = 50
The test consisted of 50 problems.

Answer:
∠ 5 = 40°
Step-by-step explanation:
∠ 1 and ∠ 2 are adjacent angles and supplementary, thus
∠ 2 = 180° - ∠ 1 = 180° - 140° = 40°
∠ 5 and ∠ 2 are alternate angles and congruent , thus
∠ 5 = 40°
