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.

Step-by-step explanation:
well because if you divide 840 by 36 you get 23.33 if you divide 840 by 3 its 280, if you divide that by 23.33 you get 12 percent.
Answer:
(0, 3 )
Step-by-step explanation:
To find the y- intercept , substitute x = 0 into f(x), that is
f(0) = 3 ×
[ note
= 1 ]
= 3 × 1
= 3
y- intercept = (0, 3 )
Answer: the width should be 12 i might be wrong i might of overthinked it the question ;-;
