Answer:
m + 10 = 39
Step-by-step explanation:
In 10 years she will be 39, so you will add 10 to her age right now, which is m, so m + 10 = 39
Rearrange: 3 + x + 1 -(2) = 0
Solve: x + 2= 0
So the value of "x" is -2
i really appreciate this post you are the real mvp
Answer:
a y = 2
b.y = 14
c. y =56
Step-by-step explanation:
a .6 (1)- 4=2
y=2
b. 6 (3)- 4
=18-4
y=14
c. 6 (10) - 4
= 60 - 4 =56
4 and -2.5
You can get this by first factoring the equation.
(2x + 5)(x - 4)
Then set both equal to zero and solve individually.
