Answer: 40x
Step-by-step explanation: addion multiplcation and divion
4x- 4= 6x + 8
First combine like terms
4x - 6x = 8 + 4
-2x = 12
Divide each side by 2
x= -6
Number 2
1/3x + 4=10
Multiply each side by 3
x+ 12=30
x = 30-12
x=18

For this case what you should do is use the linear equation that Bryce wrote and replace the corresponding value of y which is 67.5 inches. Then, you must clear x to find the height.
We have
y = 1.123x-6.443
67.5 = 1.123x-6.443
Clearing x
x = (67.5 + 6.443) / (1.123) = 65.84
The best prediction of Riley's height is 65.84 inches.
answer
B) 65.84 inches
