Answer:
<h2><u><em>
Infinitely many</em></u></h2>
Step-by-step explanation:
How many solutions does the equation 4s + 8 = 3 + 5 + 4s have?
4s + 8 = 3 + 5 + 4s
4s - 4s = -8 + 8
0 = 0
this equation is always true
so
your answer is Infinitely many
you can replace the "s" with any value
Answer:
It will take one day and they will each sell 20 cars.
Step-by-step explanation:
Choose variables to represent each thing of interest:
- Fairfax = F
- Mason = M
- days = d
F = 19 + 1(d)
M = 18 + 2(d)
The goal is for F and M to equal one another, so set the equations equal to one another.
19 + 1d = 18 + 2d
1 = d
So, it will take one day.
Now, solve for F and M
F = 19 + 1(1) = 20
M = 18 + 2(1) = 20
Answer:
3x-6
Step-by-step explanation:
(f+g)(x) would be the same as saying 2x+1+x-7, so then you would just simplify by combining like terms.
