3 (2x + 4y - y) Combine like terms (4y and -y)
3 (2x + 3y) Use the Distributive Property [(3 · 2x) + (3 · 3y)]
6x + 9y
Answer:
Step-by-step explanation:
f(n)=64+6n
f(n-1)=64+6(n-1)=64+6n-6=f(n)-6
f(n-1)+6=f(n)
or f(n)-f(n-1)=6
You just got to plug and solve...
a³-2bc
(2)³-2(-3)(4)
Solve and you get 32!
X + X+ 120 = 250
2X + 120= 250
2X = 130
X = 65
X + 120 = 185 boys
Boys/total= percent
185/250= 74%
Answer is 74%
Have a nice day!
