Answer:
x = 1.2
Step-by-step explanation:
[tex]\frac{10x-3}{3}[/tex] + [tex]\frac{5x+2}{4}[/tex] = 5
You would want to make the denominators of both fractions the same first. Their lowest common multiple is 12, so we shall make the denominators 12 by multiplying the first fraction by 4 and the second fraction by 3.
[tex]\frac{4(10x-3)}{12}[/tex] + [tex]\frac{3(5x+2)}{12}[/tex] = 5
Simplify.
[tex]\frac{40x-12}{12}[/tex] + [tex]\frac{15x+6}{12}[/tex] = 5
Now we can combine both fractions together since their denominator is the same.
[tex]\frac{40x-12+15x+6}{12}[/tex] = 5
Simplify.
[tex]\frac{55x-6}{12}[/tex] = 5
Isolate 55x-6.
55x-6 = 5 × 12
Simplify.
55x-6 = 60
Isolate the 55x.
55x = 60+6
Simplify.
55x = 66
Find x.
x = [tex]\frac{66}{55}[/tex]
Simplify.
x = 1.2

Jackson went to a store that was selling everything at 25% off! The price of a coat that he bought was $34.50 after taking off the discount. What was the original price of the coat?
Answers
Given:
The price of coat after discount of 25% is $34.50.
To find:
The original price of the coat.
Solution:
Let x be the original price of the coat.
Price of coat after discount = Original price - 25% of original price
On substituting the values, we get
[tex]34.50=x-\dfrac{25}{100}\times x[/tex]
[tex]34.50=x-0.25x[/tex]
[tex]34.50=0.75x[/tex]
Divide both sides by 0.75.
[tex]\dfrac{34.50}{0.75}=x[/tex]
[tex]46=x[/tex]
Therefore, the original price of the coat is $46.

Answers
Answer: -9/4
Step-by-step explanation:
First you subtract 7/2 from both sides of the equation
3x + 7/2 - 7/2= x - 1 - 7/2
Next what you do is simplify one you add 3 + 7/2 which is 9/2
Then you subtract X from both sides of the equation
3x - x = x - 9/2 - x
combine the terms
2x = -9/2
divide both sides of the equation by the same term
2x/2 = 9/2 / 2
cancel the terms and divide the numbers
x=-9/4

15 16 18 01:34:02 Kate begins solving the equation (6x – 3) = }(6x – 4). When she adds 2 to both sides, the equation 4x = 3x results. Which solution will best illustrate what happens to x ? Her work is correct and is shown below. (6x – 3) = (6x – 4) O The equation has infinite solutions. O The equation has one solution: x = 0. 4x - 2 = 3x - 2 O The equation has one solution: x = 4 O The equation has no solution.
Answers
The true statement is that the equation has one solution; x = 0
How to determine the equation solution?We have:
2/3(6x – 3) = 1/2(6x – 4)
When 2 is added to both sides, the equation becomes
4x = 3x
Subtract 3x from both sides of the equation
x = 0
Hence, the equation has one solution; x = 0
