An author is writing and illustrating a new book. The ratio of pages with text to pages with illustrations is represented in the
Nitella [24]

Answer:

Th number of pages is 33

Step-by-step explanation:

The ratio of the number of pages of text shown in the  illustration is 3:2. This implies that for every 2 pages of illustrations, there are 3 pages of text. Therefore, for 22 pages of illustration we shall have;

2 page of illustration = 3 page of text

Then

22 page of illustration  =  x pages of text

Then by Cross multiplication

22 \times 3 = x \times 2

66 = 2x

x =\frac{66}{2}

x = 33

Solve each equation. Explain your method.8.88=4.44(x−7)
omeli [17]
  • 8.88=4.44(x−7)

write the equation

  • 8.88 - 4.44=(x−7)

Transfer 4.44 to other side and it's sign changes from positive to negative

  • 4.44=(x−7)

After subtracting we will get result as 4.44

  • (x−7) = 4.44

Arrange the equation as variable always comes at left side.

  • x−7 = 4.44

open brakets

  • x = 4.44 + 7

transfer 7 to other side and it changes from - to + sign

  • x = 11.44
