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
Yes. Here's an example : I used 4 gallons of gas and drove 28 miles. The ratio is 4gallons for every 28 miles. 4 gallons: 28 miles.
Answer:
if b>0
then A<B
Step-by-step explanation:
Of means multiply and is means equals
12.5% *A = b
.125A = b
Divide by .125
.125A/.125 = b/.125
A = 8b
30% *B = 3b
.30B = 3b
Divide by .3
.3B/.3 = 3b/.3
B = 10b
8b vs 10 b
if b>0
then A<B
