D
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
3(x + 2)
=24
Divide each side by 3
3/3(x+2) = 24/3
x+2 = 8
Subtract 2 from each side
x+2-2 = 8-2
x = 6
Answer: F) 7 mph
<u>Step-by-step explanation:</u>
The line you drew is correct but you read the graph wrong.
The line drawn from 15 hours of training (bottom axis) meets the "line of best fit" at the average running speed (left axis) between 6 and 8, which is 7.
Answer:r=7/7744
move all terms to the left:
(7/22)(44)-(2r)=0
add all the numbers together, and all the variables
-2r+(+7/22)44=0
multiply parentheses
-2r+7/22*44=0
multiply all the terms by the denominator
-2r*22*44+7=0
multiply elements
-1936r*4+7=0
multiply elements
-7744r+7=0
move all terms containing r to the left, all other terms to the right
-7744r=-7
r=-7/-7744
PRQ and QRS should add to PRS
(3x-8)+(2x+6)=98
5x-2=98
5x=100
x=20
Plug 20 into both expressions:
3(20)-8
60-8
52 degrees= PRQ. <===========
2(20)+6
40+6
46 degrees= QRS. <==========
