Craig uses a ruler to determine the length of two pieces of metal. He records the length of each piece of metal as a rational nu

mber. Which statement best explains whether the sum of the two lengths Craig recorded must also be a rational number?
A. When adding two rational numbers a/b and c/d, the numerators a and c do not have to be integers. Therefore, the sum does not have to be a rational number.

B.When adding two rational numbers a/b and c/d, the common denominator bd does not have to be an interger. Therefore, the sum does not have to be a rational number.

C. When adding two rational numbers a/b and c/d, the sum is ac/bd, and both the numerator and denominator are integers. Therefore, the sum must be a rational number.

D. When adding two rational numbers a/b and c/d, the sum is ad+bc/bd, and both the numerator and denominator are integers. Therefore, the sum must be a rational number.

In this situation, which equation is NOT equivalent to the rest? Mrs. Jones deducts $3 from each of her 5 children's allowances
lawyer [7]

Answer:

c. 5x - 3 = 125

Step-by-step explanation:

Mrs. Jones deducts $3 from each of her 5 children's allowances this week because they didn't finish their chores. They then received a total of $125 in allowance. a. 5(x - 3) = 125

b. 5x - 15 = 125

c. 5x - 3 = 125

d. 5x = 140

Solution:

Let x represent the allowance for each of Mrs. Jones children. Since she deducts $3 from each children because they didn't finish their chores, the allowance for each child becomes x - 3.

There are 5 children, hence the allowance for the 5 children would be:

5(x-3)

Since they received a total of $125 in allowance, hence:

5(x-3) = 125

5x - 15 = 125

5x = 125 + 15

5x = 140

Option c is wrong

Victor is in the 28% tax bracket.
castortr0y [4]

Incomplete question. I've made some assumptions to provide clarity.

Answer:

<u>a. $45,743.07</u>

<u>b. $44,843.07</u>

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

Let's assume Victor is a single filer with an income of $100,000.

Using the 2017 tax bracket rates for single filers, Victor would be expected to pay:

- 10 percent on the first $9,325 = 10% x 9525 =$932.5

- plus 15 percent of the amount between $9,326 and $37,950 (37950-9326) x 15% = $4293.6

- plus 25 percent of the amount between $37,951 and $91,900 (91900-37,951 ) x25% = $13487.25

- plus 28 percent of the amount over $91,901-$191,650 (191650-91901) x 28% = 27929.72

Total=  $46,643.07

Minus $900 tax credit= $46,643.07-$900= $45,743.07

Minus $900 charitable contribution = $45,743.07-$900= $44,843.07
