Question

Type the correct answer in each box. Use numerals instead of words. If an answer for this question is not a whole number, enter it as a decimal. The expression 220.03 - (55.27 + 115.32) represents A. The expression 111.45 + (198.22 - 76.76) represents B. The expression 28.15 - 202.98 - 108.46 represents C. Express all values in decimal form. The numerical value of (A - B) + C is . The numerical value of C - (B + A) is

Answer 1

A=

Explanation:

Answer 2

`(A-B)+C=-466.76`

`C-(B+A)=-565.64`

Explanation:

Given : Expression A -
`220.03-(55.27+115.32)`

Expression B -
`111.45+(198.22-76.76)`

Expression C -
`28.15 - 202.98 - 108.46`

To find : Express all values in decimal form.

1) The numerical value of (A - B) + C

2) The numerical value of C - (B + A)

Solution :

First we solve the expressions,

`A=220.03-(55.27+115.32)`

`A=220.03-(170.59)`

`A=49.44`

`B=111.45+(198.22-76.76)`

`B=111.45+(121.46)`

`B=232.91`

`C=28.15 - 202.98 - 108.46`

`C=-283.29`

1) The numerical value of (A - B) + C

Substitute the values in the expression,

`(A-B)+C=(49.44-232.91)+(-283.29)`

`(A-B)+C=-183.47-283.29`

`(A-B)+C=-466.76`

2) The numerical value of C-(B+A)

Substitute the values in the expression,

`C-(B+A)=(-283.29)-(232.91+49.44)`

`C-(B+A)=-283.29-282.35`

`C-(B+A)=-565.64`
