Answer:
28
Step-by-step explanation:
The product of -4 and the unknown number n is -4n.
4 more than the product of -4 and the unknown number n is -4n + 4.
Letting n = -6 results in the value -4(-6) + 4, or 24 + 4, or 28.

Answer:
then x = 2.
Step-by-step explanation:
4 multiplied by 2 = 8
8 divided by 2 equals 4
Putting it together:
4(2)/2=4
Answer:
c = 69 and h = 51
Step-by-step explanation:
You will need two different equations here
use variable c as coffee and variable h as hot chocolate
c + h = 120
1.80c + 3.15h = 284.40
By moving variables, you can alter the first equation
h = 120 - c
Now insert this into the second equation
1.80c + 3.15(120 - c) = 284.40
Multiply
1.80c + 378 - 3.15c = 284.40
Subtract the c
-1.35c + 378 = 284.40
Subtract 378 from both sides
-1.35c = -93.6
Divide both sides by -1.35
c = 69
Then plug into the first equation
69 + h = 120
Subtract 69
h = 51
