140
Step-by-step explanation:
20+4(s)=
20+4(30)=
20+ 120=
140
48 ÷ 6 = 8
16 ÷ 2 = 8

I hope that helps!
Step-by-step explanation:
x = price per video game
y = price per CD
164 = 5x + 3y
and then we know
x = y + 12
now we can use this as substitute in the first equation :
164 = 5(y + 12) + 3y = 5y + 60 + 3y = 8y + 60
104 = 8y
y = $13
x = y + 12 = 13 + 12 = $25
so, each CD costs $13.
In the equation f(n) = 2n - 7
f(11) = 15
Answer:
The answer is 3.
Step-by-step explanation:
Since you do the parentheses first, you will figure out what why is. Y = 3, because 3*3 =9, and 9-9=0.
