-10x-11=-12x+21
Move variable to the left side and change its sign
Move constant to the right side and change its sign
-10x+12x=21+11
2x=21+11
2x=32
Divide both sides by 2
X=16

-10x=-12x + 21 + 11
-10x= -12 + 32
-10x + 12x = 32
2x = 32
X = 32/2

For number 6 can anyone tell me the answer
slamgirl [31]
The perimeter of MATH is 4w + 6 and the perimeter of GEOM is 6w - 8. the perimeters are the same so set them equal,
  4w + 6 = 6w - 8... use inverse to get all like terms on opposite sides
-4w + 8 = -4w + 8
        14 = 2w... divide both side by 2 to get w alone
       ÷2  = ÷2
          7 = w
so B. 7 is the answer

SVEN [57.7K]

Answer:

a) x = 13

b) x = 7

Step-by-step explanation:

A) Since they have the same base of 2 so

x + 4 + (-5) = 12

          x - 1 = 12

               x = 13

b) Since they have the same base of -3 so

8 + x + 4 = 19

   x + 12 = 19

          x = 7

How many units of a 10% solution are needed to prepare 500 units of a 2% solution?
Akimi4 [234]
First find how many units of solution there is:

500* 2% = 500(.02) = 10 units

You need 10 units of solution in 'x' units of a 10% solution.

x*10% = 0.1x = 10 units   ----->  x = 10/0.1 = 100

100 units are needed
