Answer:
x = 50, y = 10
Step-by-step explanation:
Answer:
x = -7
Step-by-step explanation:
Use the distibutive property on both side:
Right side:
4 ( 1 - x )
( 4 x 1 ) + 4 x -X )
4 - 4x
Left side:
-3 ( x + 1 )
( -3 x X ) + ( -3 x 1 )
-3x -3
4 - 4x + 2x = -3x - 3
Combine like terms:
( 2x + ( -4x ) ) + 4 = -3x - 3
-2x + 4 = -3x - 3
Add 3 to each side:
-2x + 7 = -3x
add 2x to each side:
7 = -x
Divide each side by -1:
-7 = x
Step-by-step explanation:
1. d = rt
Divide t from both sides.
2. PV = nRT
Divide P from both sides.
3. 
Add g to both sides.
= g + a
Now multiply by 2 on both sides.
x = 2(g + a)
(or, x = 2g + 2a)
4. g
Divide g from both sides.
Now subtract 1.5 from both sides.
h = 
5. 
n = 
Answer:
3
Step-by-step explanation:
y/x=12/9=4/3
when y is 4 x is 3
First we divide 162 by 18. Our answer is 9. She earns 9$ for every hour she works. We then divide 207 by 9 and we get 23.
Answer: 23
