Answer: \bold{x=\dfrac{c}{a-b},\qquad x=7}

<u>Step-by-step explanation:</u>

Move all of the x's to one side and everything else on the other.

ax = bx + c

ax - bx = c      <em>subtracted bx from both sides</em>

x(a - b) = c       <em>factored out the like term of "x" on left side</em>

x=\dfrac{c}{a-b}          <em>divided both sides by (a- b)</em>


2x = x + 7  → a = 2, b = 1, c = 7

                    x=\dfrac{7}{2-1}

                     x = 7

<u>Check:</u>

2x = x + 7

<u>-x  </u>  <u>-x       </u>

x =       7

The parallelogram shown below has an area of <br> 20 units squared. Find the missing base
valkas [14]

Answer: 5 units

Step-by-step explanation:

The area of a parallelogram is A=bh. SInce we know the area and the height, we can directly plug the values into this equation and solve for the base.

20=b(4)         [divide both sides by 4]

b=5 units

Can someone please help me? I don't understand this problem. How would they be the same???
musickatia [10]
Area of rectangle = 15 x 8
                           =120

area of parallelogram = 8 x 15 
                               =120
so, they have the same area, because the length of a rectangle is the same as the height of a parallelogram and also for the base.
