Answer:

All steps are correct

Step-by-step explanation:

|2x − 5| − 2 = 3

Step 1

|2x − 5| = 3 + 2  (adding 2 on both sides)

Step 2

|2x − 5| = 5  

Step 3

2x − 5 = 5 or 2x − 5 = −5   (on opening the modulus, we get 2 cases)

Step 4

2x = 10 or 2x = 0   (adding 5 on both sides)

Step 5

x = 5 or x = 0   (dividing by 2 on both sides)

Hence, each step was correct

|2x - 5|  - 2 = 3    |add 2 to both sides

|2x - 5| = 5

2x - 5 = 5 or 2x - 5 = -5    |add 5 to both sides

2x = 10 or 2x = 0    |divide both sides by 2

x = 5 or x = 0

All steps are correct.

Here is a photo of what I chose as my equivalent numbers (Red represents my work, blue represents which step comes next, and highlighter shows what the answer is). My reasoning that 1/2 and 5/10 are equivalent is because 5/10 divided by 5/5 is 1/2.

each month luke earns a salary of 3500 plus 15%at the total ampount of his sales for the month luke earned 4760 in march .what w
sineoko [7]
Hey. Let me help you on this one.

In order for us to solve this problem, we will need to determine how much money Luke has earned from the sales this month, and find the total amount of sales in dollars.

I will also be attaching an image to this answer in case you still don't understand the question, or need extra help with your studies.

We know that Luke's salary is $3500, and anything above that amount of money comes from sales he makes. We also know that he only gets 15% from sales. Let's determine how much he earned from sales this month.

4760-3500=1260

Luke has earned $1260 from the sales he made. Since it's only 15% of the full amount, we need to convert this value to 100%. We can do this by finding 1% of the unknown number, and multiplying it by 100 to show the full amount of sales.

Let's find 1% of the total amount of sales. Since 1260 is 15% of the unknown total, let's divide it by 15.

\frac{1260}{15} =84

Great. $84 is 1% of the total amount of sales. All we need to do is multiply it by 100 to show 100% of the total amount of sales.

84*100=8400

Awesome. We now know the amount of sales in dollars that Luke has brought to the company.

Answer: Total amount of Luke's sales in dollars is $8400
