You work 40 hours per week and spend 5 hours per week commuting to and from work. Your friend works 56 hours per week and spends 7 hours per week commuting to and from work. Do you each have the same ratio of commute time to work hours per week? Are these two quantities in proportion?

the answer is yes

Step-by-step explanation:

your ratio..40:5

friends ratio..56:7

each quantity is 8

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
