Answer:
C: They add up to 180 degrees, because they are a pair of supplementary angles
Step-by-step explanation:
<1 and <2 add up to 180 degrees, so they are supplementary angles.
Complementary angles add up to 90 degrees.
1.)-2v-7=-23
-2v=-16
v=8
2.)x/3-10=-12
x/3-10=-12
x/3=-2
x=-6
3.) x/4+10=14
x/4=4
x=16
1/3b = 4/5
Do the cross multiplication
1(5) = 3b(4)
5=12b

Answer:
She sold 39 tall candies and 52 short candies
Step-by-step explanation:
x is all the tall candies
y is all the short candies
x+y=91
8x+5y=572
Use the method of Substitution to find out both x and y.
x=91-y
8(91-y)+5y=572
728-8y+5y=572
728-3y=572
3y=156
y=52
x+52=91
x=39
