The answer for your question is 4x^2-15x+6+ 2/3x+5
Answer: 15 hours
Step-by-step explanation:
Total cost of TV = $252, Savings= $87. So, she will require, $252-$87 = $165 to buy TV.
Also, it's given that, she gets paid $11 per hour.
Therefore, she will require 165/11 hours = 15 hours to buy new Tv at the wage rate of $11/ hour.
Solve for x:
1.
4x - 7 = 3
Add 7 to both sides
4x = 10
Divide both sides by 4
x = 10/4
Simplify:
x = 5/2
Answer for question 1: x = 5/2
2.
13 + 2x/3 = 15
Multiply both sides by 3
39 + 2x = 45
Subtract 39 from both sides
2x = 6
Divide both sides by 2
x = 3
Answer for question 2: x = 3
3.
10x + 7 = 15
Subtract 7 from both sides
10x = 8
Divide both sides by 10
x = 8/10
Simplify
x = 4/5
Answer for question 3: x = 4/5
Ok so the average is 50
average of x number of things is
(add value of all things)/x=average
4 test scores needed
so divide by 4
3 test scores ar known
average is 50
x= missing score
(43+48+42+x)/4=50
times 4 both sides
133+x=200
minus 133 both sides
x=67
a score of 67 is needed
Answer:
The answer is 13. She has 23 coins and it equals $4.25. So, if she has 10 dimes, that would equal $1 and if she has 13 quarters, that would equal $3.25.
