Answer:
m= -10.5
Step-by-step explanation:
4m-6(2m-3)=90
distribute 6
4m-12m+6=90
combine like terms
-8m+6=90
subtract 6
-8m=84
divide both sides by -8
answer
m= -10.5
Answer:
Since it does not plug in to the second linear equation, the ordered pair is not a solution of the linear system.
Step-by-step explanation:
(-1,3); y = -7x -4 y = 8x + 5 3 =7 - 4 3 =/ - 8 + 5
(3x + 15) + (x + 7) = 94
4x + 22 = 94
4x = 94 - 22
4x = 72
x = 18
You place it inside x + 7
So, 18 + 7 = 25
Angle CBD = 25
When I did the math in my head the fraction I got was 20/100000. 20/100000 as a decimal form is 0.0002.
