Answer:
one sec i will answer this
Step-by-step explanation:
12c - 53 = 91
First add 53 to each side. This cancels it out on the left (-53 + 53 = 0)
12c = 91 + 53
12c = 144
Now divide by 12 on each side. This cancels the 12 on the left (12/12 = 1)
c = 144/12
c = 12
Answer:
Alex will need 14 bags
Step-by-step explanation:
B= 4(2x+7)+3(2x+7)
and
2x+7=2
First, we should solve the second equation to obtain x:
2x+7=2
2x=2-7
x= -5/2
Then, we use this answer to calculate B:
B=4(2(-5/2)+7)+3(2)
B=4(-5+7)+6
B=4(2)+6
B=8+6
B=14
Alex will need 14 bags
The answer is A
your expression said 5×20=100 +3×20=60 So 100+60=160
now the option A is5+3=8 then 8×20=160 there the same product
