because if x is 5 then 6(5)
and 6x5=30
Answer:
x = 6
Step-by-step explanation:
1/2(18-5x)=1/3(6-4x)
9 - 5/2x = 2 - 4/3x
7 = 7/6x
x = 6
Answer:
f(-3)=4
Step-by-step explanation:
Substitute x=-3 into the function
f(-3)=(-3)^2-5
f(-3)=9-5
f(-3)=4
Answer:
GCF: 20
Step-by-step explanation:
The thing you want to do is factor both numbers down to their lowest primes.
40:2 * 2 * 2 * 5
60:2 * 2 * 5 * 3
Now underline what is in both sets of primes. I'll bold them. The number that is bolded comes from 2 * 2 * 5 which is 20
The highest common factor is 20
