Answer:
No he is wrong
Step-by-step explanation:
Evan was not correct 125% means he over doubled his time doing homework. To double his time he would need 40 hours, and he only did 25.
Increase: 5 hrs
Percent of increase: 20%, because 5/25=20%
3.50x + 5.50x + 6 = 51
# 10
9x + 6 = 51
Subtract 6 from both sides
9x = 45
Divide both sides by 9
x = 5
#11
5x - 18 - 4x = -36
x -18 = -36
Add 18 to both sides
x = - 18
Answer:
Part (A) Factored using GCF is: 2(x² + 2) → (GCF is 2)
Part (B) Factored using GCF is: 2x³(3x-1) → (GCF is 2x³)
Step-by-step explanation:
Greatest Common Factor or GCF, is whichever value that fits into both terms. For example if you have 2, 4, and 6, 2 is the biggest value that fits into all 4 terms.
To factor using GCF, simply find the GCF of both terms, and take it out, then multiply what you have remaining by whatever the GCF is.
Step-by-step explanation:
9y-3=?
9(10)-3
=90-3
=87
11. 9 + 8 = 8 + 9
12. 91 + 0 = 91
