18 = (240/100) x what;
what = 18 x (100/240);
what = 1800/240;
what = 7.5;

Set up an equation: 18=240%•X. Get the unknown by itself: 18/2.4=X. 7.5=X. 18 is 240% of 7.5 :)

An equation is shown below:
IrinaK [193]
5(2x - 8) + 15 = -15
               -15      -15     subtract 15 from each side
5(2x - 8) = -30
  ÷5             ÷5             divide both sides by 5
2x - 8 = -6
     +8    +8                   add 8 to each side
2x=2
÷2  ÷2                          divide both sides by 3
x = 1

Checking:
5(2(1)-8) + 15 = -15
5(-6) + 15 = -15
-30 + 15 = -15
-15 = -15             Correct! x=1

Answer:

Area of the figure = 254.5 cm²

Step-by-step explanation:

<u><em>Area of rectangle = Length × Width</em></u>

<u><em>Area of triangle = 1/2(base × Height)</em></u>

<em>Dividing the figure into parts for convenience</em>

So,

Rectangle 1  (the uppermost):

4 × 6 = 24 cm²

Rectangle 2 (below rectangle 1):

15 × 8 = 120 cm²

Rectangle 3 (with rectangle 2):

11 × 4 = 44 cm²

Triangle 1 :

1/2(7 × 19) = 133/2 = 66.5 cm²

<em>Now adding up all to get the area of the figure:</em>

Area of the figure = 24 + 120 + 44 + 66.5

Area of the figure = 254.5 cm²
