<h3><u>Answer</u> :</h3>

Given that, <u>-3b + (-9) = (-3)</u>

We have to find value of b.

⭆ -3b + (-9) = (-3)

⭆ -3b - 9 = -3

⭆ -3b = -3 + 9

⭆ -3b = 6

⭆ 3b = -6

⭆ b = -6/3

⭆ b = -2 [Final answer]

Answer:

Whole #'s: All natural numbers plus 0

Integers: Whole numbers and their opposites

Rationals: Can be expressed as ratios, repeating numbers, decimals, so on.

1.

-2/5 is a fraction or ratio, meaning it doesn't belong in whole NOR integer.

-2/5 belongs in the rationals box.

-7.8 is negative, but it is a decimal, so it belongs in the rationals box.

1/10 is not a whole, not an integer, but a rational number.

13 is a whole number, integer, and rational, so it belongs in the whole box.

10 is also a whole number grouped under the categories given.

-5 is the opposite of 5, and whole numbers aren't negative, so -5 belongs in the integers box.

-8/4 is a fraction, not considering its simplified form that would give -2, so it belongs in the rationals box.

2.

We know there are 208 pages in total. On Monday, she read 3/8 of the pages. This can be demonstrated as 208 * 3/8, which is 78. 208-78 = 130.

We know there are 130 pages left. On Tuesday, she reads 28 pages. 130-28=102

We know there are 102 pages left. On Wednesday, she read 1/4 of the total pages. 1/4 (of) 208 is 1/4*208, that is 52.

To know how many pages are left, we subtract her read pages from the remaining pages. 102-52 = 50.

Amanda has 50 pages left until she finishes the novel.

Hope this helped.
