Answer:
r = - 29
Step-by-step explanation:
Given
- 3r = 87 ( divide both sides by - 3 )
r = 
= - 29
The answer would be a . $43.2 because your multiplying the number by 0.08
Answer:
A. {x | x < 8}
Step-by-step explanation:
First, we divide both sides by 3.
3(x - 2)/3 < 18/3
Then simplify.
x - 2 < 6
Lastly, add 2 to both sides.
x - 2 + 2 < 6 + 2
<u>x < 8</u>
1)
g+4-3g=1+g
subtracting g from both sides
4-3g=1
subtracting 4 from both sides
-3g=-3
g=1
2)
-6a+3=-3(2a-1)
extending the right side
-6a+3=-6a+3
adding 6a to both sides
3=3
which is an identity
3)
0.5b+4=2(b+2)
extending the right side
0.5b+4=2b+4
subtracting 0.5 b from both sides
4=1.5b+4
subtracting 4 from both sides
0=1.5b
b=0
4)
8-(3+b)=b-9
subtracting 8 from both sides
-(3+b)=b-17
extending the left side
-3-b=b-17
adding b to both sides
-3=2b-17
adding 17 to both sides
14=2b
b=7
