Y=7-2×(-5/2)
Y=7+5
Y=12
The answer is C
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.
The answer is a have a great day/night !
To simplify this expression, first you would have to distribute the negative or subtraction throughout the second group of parentheses.
After we do this, we get the simplified expression:
ab + 8a + 1 + 6ab - 4
Now, we must simplify like terms, meaning combine the terms that have the same variable.
7ab + 8a - 3
That is your final answer ^^^
