b.7.69
Step-by-step explanation:
188/4=29.5
29.5 gal per mile
227/29.5=7.69
D) 1•x=5, 1•5=5 8•5=40, the answer is 40/5 CDs
E) 3/3=1, 26.25/3= 8.75. The answer is 1/8.75
F) 10/10=1, 120/10= 12. The answer is 1/12
G) 2•x=12, 2•6=12, 120•6= 720. The answer is 12/720

B.
When two lines intersect they form two pairs of opposite angles.
Vertical angles are always congruent, which means that they are equal.
so m<7 = m<8 or m<3y + 19 = m<5y-29
C. solve for y and measure <7 and <8
3y + 19 = 5y-29
5y - 3y = 19+29
2y = 48
y = 24
so
5y-29 = 5(24) - 29 = 91
3y + 19 = 3(24) + 19 = 91
so <7 = 180 - 91 = 89
<7 = <8 = 89
