Answer:
Step-by-step explanation:
Q3
Corresponding angles are congruent
- 6x - 11 = 37
- 6x = 11 + 37
- 6x = 48
- x = 8
Q4
Angle2 is complementary with 142 and alternate interior with 2(x + 9)
- 142 + 2(x + 9) = 180
- 142 + 2x + 18 = 180
- 2x + 160 = 180
- 2x = 20
- x = 10

Charlie used a coupon and pos 9.99 for a pizza and it normally costs 15.99 14* the percentage of the change would be %1.28
Divide each set to see if the answers are identical:
A: 3/2 = 1.5
6/3 = 3
Answers are not the same so this is not proportional.
B: 20/4 = 5
24 /6 = 4
Answers are not the same so this is not proportional.
C: 27/9 = 3
81/27 = 3
Answers are the same so this is proportional.
D: 8/2 = 4
16/8 = 2
Answers are not the same so this is not proportional.
The answer is C.
Set up the equation by writing the number of students in the ratio as a fraction:
3/4= (245-x)/x Cross multiply:
3x= 4(245-x) Multiply on right:
3x= 980-4x Add 4x on both sides:
7x= 980 Divide both sides by 7:
x= 140 this is how many girls there are. And:
245-140= 105= boys
