The answer is 4 x^2y. <em> I cannot explain to you how I know I'm right. I'm the type of person who HAS to do the work in their head . I am a very experienced person in any Mathematics area. I am NOT saying I'm an expert , but it is one of my strongest subjects . </em>

Answer:

4y

Step-by-step explanation:

Parenthesis means they are multiplied , so writing all the top(numerator) values in top and bottom(denominator) values in bottom we get

\frac{-2*5y*(-2x)}{5x}

simplify by cancelling the common factor 5 and x from top and bottom

we get

4y

How do i solve for <br> (2x/5)+1=13/5
NNADVOKAT [17]

Answer:

x = 4

Step-by-step explanation:

  1. \frac{2x}{5} +1 = \frac{13}{5}  
  2. \frac{2x+5}{5} = \frac{13}{5} divide both sides by 5
  3. 2x + 5 = 13 subtract 5 from both sides
  4. 2x = 8 divide both sides by 2
  5. x = 4

What is the solution to this liner equation d-10-2d+7=8+d-10
Vladimir79 [104]
Group like terms then
add like terms

d-2d-10+7=8-10+d
-d-3=-2+d
add d to both sides
-3=-2+2d
add 2 to both sides
-1=2d
divide both sides by 2
-1/2=d

GH has a midpoint at M (5,9). Point H is at (8,9). Find the coordinates of point G
natta225 [31]

Answer:

(2,9)

Step-by-step explanation:

The midpoint of a point is halfway between two points. The distance between the midpoint and point H is 3 because the distance from 5 to 8 is 3. Therefore 3 away from 5 would be 2.
