Answer:
<h2>A. Switch the inequality sign</h2>
Step-by-step explanation:
When multiplying, you must switch the inequality sign. This is also true when dividing.
EXAMPLE 1:
-4r < -21
Note: We reversed the inequality sign when we divided by -4
r > 5 1/4
EXAMPLE 2:
x/-5 <u>></u> 7
Note: We reversed the inequality sign when we multiplied by -5
x <u><</u> -35
I'm always happy to help :)
Answer:
x + y <u>></u> 15
10x + 5y <u><</u> 100
we will put it in terms of y
y <u>></u> 15 - x
and
5y <u><</u> 100 - 10x
y <u><</u> 20 - 2x

Answer:
x=1
Step-by-step explanation:
7/3 x + 1/3x = 1 + 5/3 x
Combine like terms
8/3 x = 1 +5/3 x
Subtract 5/3 x from each side
8/3x -5/3x = 1 + 5/3x -5/3x
3/3x = 1
x =1
