If 52 is 130 percent of a number, Is the number greater or less than 52?

Answers


Well, I don't know.
Let's think about it.

100% of anything is all of it.
More than 100% of anything is more than it.

100% of a number is all of the number.
More than 100% of a number is more than the number.

If 100% of the number is 52, then 52 is all of the number.
If more than 100% of the number is 52, then 52 is more than the number.

(So the number is less than 52.)


What is 10 = -9/2x - 7 - 3/2x
A = -17/6
B = -1/2
C = 17
D = 17/6

Answers

Answer:

x= -17/6

Step-by-step explanation:

10=-9/2x-7-3/2x

multiply all by 2

20=-9x-14-3x

add -9x to -3x

20=-12x-14

replace 20 with -12x and put -12x as a positive

12x=-14-20

add -14 to -20

12x=-34

divide both sides by 12

x= -17/6
