Answer:
D.5
Step-by-step explanation:
You can write the following equations from the information given:
y=x+3 (1)
11x+5y=47 (2)
x is the number of hardback books
y is the number of paperback books
You can replace (1) in (2):
11x+5(x+3)=47
11x+5x+15=47
16x=47-15
16x=32
x=32/16
x=2
Then, you can replace the value of x in (1) to find the value of y:
y=2+3
y=5
According to this, the answer is that Jamal bought 5 paperback books.
Answer:
it's the bottom left one
Step-by-step explanation:
Im just a kid, don't ask
So -1/4x+1/2 x would be 1/4 x because -0.25+0.5=0.25
translating 2/3 into 4/6, so we do 4/6-2/6 which would be 1/2.
