If you would like to find the product, you can calculate this using the following steps:

-mnp * (3m - 5n7p) = -mnp * 3m + mnp * 5n7p = -3m^2np + 35mn^2p^2

The correct result would be -3m^2np + 35mn^2p^2.

25m + 100 - 24m - 75 = 68.

Maksim231197 [3]

25m+100−24m−75=68

Step 1: Simplify both sides of the equation.

25m+100−24m−75=68

25m+100+−24m+−75=68

(25m+−24m)+(100+−75)=68(Combine Like Terms)

m+25=68

Step 2: Subtract 25 from both sides.

m+25−25=68−25

m=43

Answer:

m=43

11 - 5 < 7

<em>Simplify</em>

6 < 7

This is true

<em>Insert 3 into the equation</em>

11 - 3 < 7

The account balance of each of three children at the end of a month is shown below:

xeze [42]

Answer:

A) See attached.

B) Cheryl owes the bank more.

Step-by-step explanation:

Given account balances:

John: -$2.75
Cheryl: -$3.00
Andrew: $2.75

(Andrew has as much savings in his account as the amount John owes).

Draw a straight, horizontal line with arrows on both ends.
Place a tick in the center of the line and label it zero.
Draw 4 evenly spaced ticks either side of the zero.
Number the ticks to the right of the zero 1, 2, 3 and 4.
Number the ticks to the left of the zero -1, -2, -3, and -4.
Mark -2.75, -3 and 2.75 on the number line.
Label the marks with John, Cheryl and Andrew.

(See attached number line).

The <u>absolute value</u> of a number is its <u>positive numerical value</u>.

To calculate how much John and Cheryl owe the bank, take the absolute values of their account balances:

John: |-2.75| = 2.75

Cheryl: |-3.00| = 3.00

As 3.00 > 2.75, Cheryl owes the bank more.
