After an overpayment last month, the balance on a customer’s billing statement is −$50.00. This month’s new charges are $124.80.
siniylev [52]

The customer’s current balance after an overpayment last month is D. $174.80.

<h3>How to illustrate the information?</h3>

It should be noted that after an overpayment last month, the balance on a customer’s billing statement is −$50.00 and this month’s new charges are $124.80.

Therefore, the customer’s current balance will be:

= $124.80 - (-$50)

= $124.80 + $50

= $174.80

HELP PLEASE HELP MEEEE PLEASEEE
salantis [7]

Answer: a. x=4 b. x=17.5

Step-by-step explanation:

a. 5x/2+1=11

subtract 1 from both sides : 5x/2=10

multiply both sides by 2 : 5x=20

divide both sides by 4 : x=4

b. 2x/7-3=2

add 3 to both sides : 2x/7=5

multiply both sides by 7 : 2x=35

divide both sides by 2 : x=17.5

The solution set of the inequality 2x − y &gt; 2 consists of all the points __ ? the line __ ?
GalinKa [24]

Answer:

  • b - below; y = 2x − 2

Step-by-step explanation:

  • 2x − y > 2
  • 2x - y + y - 2 > 2 + y - 2
  • 2x - 2 > y
  • y < 2x - 2

Solution is the points below the line y = 2x - 2

<u>Correct option is:</u>

  • b - below; y = 2x − 2

The length of 2 sides of a triangle are 12 inches and 4 inches. Which is the third side?
Westkost [7]

Answer:

Let x = the third side

 

In a triangle, the sum of any 2 sides must be larger than the third side.

I believe this is called the triangle inequality theorem.

 

We can construct 3 inequalities to obtain the range of values for the third side.

 

  (Inequality #1)   12 + 4 > x

                                  16 > x

 

  (Inequality#2)    12 + x > 4

                                    x > -8   (we can discard this ... we know all sides will be positive)

 

  (Inequality #3)   4 + x > 12

                                   x > 8

 

So when we combine these together,  

 

   8 < x < 16

 

X (the third side) must be a number between 8 and 16. but not including 8 and 16
