X=4, first you distribute the 2 to both 4x and -11 which leaves you with 8x-22+9=19 next you add -22 with 9 which leaves you -13 the eqation now at 8x-13=19 so now you add 13 to both sides now youre left with 8x=32. Now the last step is to divide 8 on both sides. so that gives you the answer or X=4

musickatia [10]

Answer:

I believe the answer would be 10%

Step-by-step explanation:

If you take 10% of 40 you get 4% however 40 is your total (100%) so therefore you would take the 4% multiply it by 2 and then you end up with 8% then you take 4% and divide it by 2 then add it on to your 8% then you end up with 10%

The length, width, and height of a rectangular prism is a, (a-13), and (a+13) respectively, which statement best describes (a-13
Nitella [24]

Answer:

a. The width of the rectangular prism is 13 units less than the length.

Step-by-step explanation:

From the information given we know that

a = length of rectangular prism and

a - 13 =  width of rectangular prism

An expression like a - 13 means that we need to subtract 13 units from the length to obtain the width of the rectangular prism.

Therefore,

The width of the rectangular prism is 13 units less than the length.
