20/5=4
25/7=<span>3.57142857143 Rounded to the nearest tenth: 3.6
4>3.6
If you want the nearest whole, you would round down to 3 because you would be short of 4.

-5(2x+1)-2x-2=17
first, distribute
-10x-5-2x-2=17
combine like terms
-12x-7=17
get the x alone, eliminate the constant
-12x=24
divide out the -12 to get the x alone.
x=-2
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable.
Answer:
Step-by-step explanation:
Plug each value of x into the equation and solve for the corresponding y value.
When x = -1, y = (-1)²-2(-1) = 3
When x = 0, y = 0² - 2(0) = 0
You can finish from here.
Answer:
eight away .7 can be used into 3 4 times with a sum of 2.8 and that leaves .2 which would be left out since it is not a whole .7 so C
