Answer:
9.333333333333
Step-by-step explanation:
5 + 1 / 3 + 4
0.5
5+a•b, 2•3 is 6, +5 is 11.
4+6•b, 6•3 is 18, +4 is 22.
I'm using PEMDAS/GEMDAS, which means I did multiplication first.
I'm assuming the / means to divide, so 11/22 is 0.5
she will need 18 boxes total :)
GCF is 9
Factor out 9 and divide what's in the parentheses by 9
9(7+5b)
