8-0.03w = 1.72w+2.75

8 = 1.75w+2.75

5.25=1.75w

w=5.25/1.75 =3

w = 3

Work: 8-.03w=1.72w+2.75
Solve for w
+.03w both sides
8=1.75w+2.75
-2.75 both sides
5.25=1.75w
÷1.75 both sides
3=w
Answer: w=3
Check your work: plug in w
8-.03(3)=1.72(3)+2.75
Multiply
8-.09=5.16+2.75
Subtract
7.91=5.16+2.75
Add
7.91=7.91

Answer is correct

Rewrite each expression without using absolute value notation |7m-56| if m<8
dusya [7]

Considering the definition of the absolute value function, the expression is written as -7m + 56.

<h3>What is the definition of the absolute value function?</h3>

The absolute value function is defined as follows:

  • |x| = x, x \geq 0.
  • |x| = -x, x < 0

That is, where the expression is negative, it is multiplied by -1, while where it is not negative the expression is kept.

In this problem, the expression is:

|7m - 56|

For m < 8, we have that one example is m = 0:

7(0) - 56 = -56.

The expression is negative, hence the signal is changed, that is:

|7m - 56| = -(7m - 56) = -7m + 56.

Readme [11.4K]

Answer: y = $7.50x + $25

Step-by-step explanation:

From the question, we are informed that Lucy is going to walk in a fundraising event to raise money for her school band and her mother has agreed to donate $7.50 to the school for each mile that Lucy walks, plus an additional $25.

The equation that represents y, the total amount of money Lucy's mother will donate if Lucy walks x miles during the event will be:

= ($.750 × x) + $25

y = $7.50x + $25

Since Lucy walks x Mike's, we multiply x by $7.50 and then add the answer to the additional $25 which is the answer gotten above.
