Answer:
A. Dividing both sides by 4 isolates the variable.
Step-by-step explanation:
In order to solve for x, you need to get it all by itself. Dividing both sides of the equation by 4 gives you 8 on the right side and only x on the left side , therefore the variable is isolated. (This uses the Division Property of Equality.)
The answer can be found by subtract the volume of the small box from the volume of big box.
Volume of the small box:
12*8*4= 384 inches cube
Volume of the big box:
20*15*9= 2700 inches cube
The space left:
2700 - 384 = 2316 inches cube

Answer:
m= <u>y2 - y1</u>
x2 - x1
m= <u>-7 + 3</u> ( I have + 3 and 4 because when negative cancel negative, it is
-2 + 4 positive)
= <u>-4</u> = 2
-2
Step-by-step explanation:
- write down the formula for finding slope.
- replace the y's and x's with the values.
- add everything together
- divide
Answer:
The best and most correct answer among the choices provided by your question is the third choice or letter C. The total number of hours is 17.
For h>7
C=210+20(h-7)
C=210+20h-140
C=20h+70, h>7
410=20h+70
20h=340
h=17 hours
