Answer:
x=4
Step-by-step explanation:
2/3(x-7)=-2
Multiply both sides by 3/2
x-7=-3
move constant to the right
x=-3+7
calculate
x=4
Answer:
100/25 = 4
so an equivalent would be 12/3
Answer:
D. Division Property of Equality
Step-by-step explanation:
-5x=4 is what we start out with
Then to isolate the x we divide -5x by -5
However because the two sides must remain equal you have to divide the other side by -5 as well
This is the Division Property of Equality which states that if you divide on one side, then you must divide on the other side as well.
Hope this helps you
Answer:
3.6
Step-by-step explanation:
The average of 9 scores is x.
average = (sum of scores)/(number of scores)
x = (sum of scores)/9
sum of scores = 9x
The sum of the 9 scores is 9x.
The tenth score is 36 more than x, so it is x + 36.
The sum of the 10 scores is 9x + x + 36 = 10x + 36.
The average of the 10 scores is (10x + 36)/10 = x + 3.6
The difference of averages is
x + 3.6 - x = 3.6
