Answer:
g(5) = -19
Step-by-step explanation:
Step 1: Define
g(x) = -3x - 4
g(5) = x = 5
Step 2: Substitute and evaluate
g(5) = -3(5) - 4
g(5) = -15 - 4
g(5) = -19
Substitute the value of the variable into the equation and simplify.

Answer:
The Correct Answer Is 4
Step-by-step explanation:
So if you have $12 and you can buy $3 with each box of envelopes, you think, how many times can 3 go into 12
count in your head, 3 6 9 12 therefore, ITS 4
here is your equation to match this:
3 x ? = 12
You probably already know this, but i simple way to figure this out is to flip the equation to
12/3 = ?
so from here you can tell that 3 goes into 12 4 times
so the equation is
3 x 4 = 12
Hope It helps!
Answer:
2
Step-by-step explanation:
Let x be the number of hours worked.
800 + 16x = 720 + 21x
800 - 720 = 21x - 16x
80 = 5x
x = 16
∴ A job that would cost the same would take 16 hours.
Now to double check...
800 + 16 x 16= 1056
720 + 16 x 21= 1056
The answers are correct.
