b) 3(4) + 2(4) = 20
c) (3(5)+2)(5-4) = 17
Step-by-step explanation:
Substitute the variables for their values and then solve from there. Hopefully this helps, I don't know if I answered your question fully.
Answer: x=45
STEPS:
1
Add the same term to both sides of the equation
2
Simplify
3
Multiply all terms by the same value to eliminate fraction denominators
4
Simplify
A. C(n)=10n+125
cost×number of buttons is equal to 10 cents times the number of buttons, plus the $125 cost of the button machine
45 = 3x3x5
Or you could simplify it to 3^2x5
Ur answer is going to be 49
