The units in the denominator are pounds ? I’m not sure hope this helps
Answer:
B. (8, -54)
Step-by-step explanation:
y = -7x + 2
Check to see if the point makes the equation true
A. (1,2) 2 = -7(1)+2 = -7+2 = 5 False
B. (8, -54) -54 = -7(8)+2 = -56+2 = -54 True
C. (5, -35) -35 = -7(5) +2 = -35+2 = -33 False
D. (1, -7) -7 =-7(1)+2 = --7+2 = -5 False
Answer:
There are 392 storybooks.
There are 49 magazines.
<h3>There are 343 more storybooks than magazines are there in the library.</h3>
Step-by-step explanation:
s = number of storybooks
m = number of magazines
The library has 441 storybooks and magazines altogether.
s + m = 441
There are 8 times as many storybooks as magazines.
s = 8m
How many more storybooks than magazines are there in the library
?
Substitute s = 8m into the original equation to find m.
s + m = 441
8m + m = 441
9m = 441
m = 441/9
m = 49
Substitute m = 49 into the original equation to find s.
s + m = 441
s + 49 = 441
s = 441 - 49
s = 392
s - m = 392 - 49 = 343
