Answer: x = 3
Step-by-step explanation:
-10x - 2y = -30
3x + 2y =9
use elimination method...
-2y and 2y = 0
-10x = - 30
3x = 9
add together...
-7x = -21
solve...
x= 3
Find the two points in your line. If the line is pointing up to the right the slope is positive (/) and if it is pointing up to the left it is negative (\).Then find the change in y and x or rise and the run. Ex. two points are (3,4) and (5,1). The change in x is -2 and the change in y is 3 so we put it as -3/2.
Answer:
x = 2.5
Step-by-step explanation:
4x-1/2 = x+7
4x-x = 7+0.5
3x = 7.5
x = 2.5
C . 70
Cuz it’s doing the letter Z
To get this answer you would need to do 6 x 3/4 (or 0.75) to get 4.5.
Leah will need 4.5 (or 41/4) yards of material.
