<span>19 + 57 + 9 = 85
Do you need farther explaining</span>
B because .06 + .12 = .18 which is 18% out of 250 people
Answer:
x = -9
Step-by-step explanation:
x - ( - 5 ) = - 4
Distribute the negative sign
x - ( - 5 ) = - 4
x + 5 = -4
Inverse operations;
x + 5 = -4
-5 -5
x = -9
Using a system of equations, it is found that the height of the TV is of 20 inches.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable h: The TV's height.
- Variable w: The TV's width.
The height of the screen of the tv is one half the width plus 5 inches, hence:
h = 0.5w + 5.
Since the width is of 30 inches:
h = 0.5 x 30 + 5 = 15 + 5 = 20.
The height of the TV is of 20 inches.

Step-by-step explanation: (Answers in bold )
24-(-14) using the keep change change rule you get 24 +14 = 38
-9*-5 =45 (negative times a negative = a positive )
31+x=15x subtract x from both sides
31=14x divide by 14
31/16 ---or---> 2.21
2x+5= 15x subtract 2x from both sides
5=13x divide by 13
5/13 or-------> 0.38
