Which system of linear equations could be used to determine which day they will jog for the same number of minutes, where d represents the
day and m represents the number of minutes?
A m= 150+1
m=22d + 2
B. m= d+ 15
m= 20 +22
cm= 2d + 15
m= d+22
D. m= 15d + 2
m= 220 + 1

i would have to say it is c.

answer: 48

just remember to use pemdas:

parentheses

expressions

multiplication

division

addition

subtraction

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8

step-by-step explanation:

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
