Answer:
The answer would be 3.6
Is it OK if I don't explain it?
Hello!
To solve this we will use substitutions and a system of equations where L= length and w=width.
128=2L+2w
L=8+3w
We will substitute L with what it says it equals in the second equation.
128=2(8+3w)+2w
128=16+8w
112=8w
14=w
Now we find the length in the second equation.
L=8+42
L=50
Now we check the length and width in the original equation.
128=100+28
128=128
The length is 50 cm, and the width is 14.
Hope this helps!
Answer:
-52
Step-by-step explanation:
-4(x + 10) - 6 = -3(x - 2)
Distribute the left side to get:
(-4x + -40) - 6
Now distribute the right side to get:
-3x + 6
Arrange the equation as the following:
-4x - 40 - 6 = -3x + 6
Add the like terms on each side:
-4x - 46 = -3x + 6
Do the inverse operation of each term:
-x = 52
Now we need to get x to become a positive, so we just divide -x by -1 to get x.
And 52/-1 to get our final answer of -52.
