Jonathan needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 3 hours and charged him $141 for parts. The total was $336. Write and solve an equation which can be used to determine x, the cost of the labor per hour.

Answers

Answer 1
Answer:   x = 65

================================================

Work Shown:

x = cost of labor per hour

3x = cost of the 3 hours of labor

3x+141 = cost of labor plus parts = total cost

3x+141 = 336

3x = 336-141

3x = 195

x = 195/3

x = 65

The hourly wage is $65 per hour for labor.

------------

Check:

1 hour = 65 dollars in labor costs

3 hours = 3*65 = 195 dollars in labor costs

195+141 = 336 dollars total

The answer is confirmed.

Answer 2
195 is the answer
336-141=195

Which equation applies the associative property of multiplication?

A: 4/9 x (-3/8) x 9/4 = 4/9 x 9/4 x (-3.8)

B:​ −12/5 x (7/12 x 1/9) x 8/5 = (−12/5 x 7/12) x (1/9 x 8/5)

C: ​(−4/11 − 2/3) − 3/4 = −4/11 − (2/3 − 3/4)

D:​ 1/2 x (5/8 + 3/6) = (1/2 x 5/8) + (1/2 x 3/6)

Answers

Answer: B

Explanation:

The associative property of multiplication is a rule that states the result of three numbers being multiplied is the same regardless of the order of the numbers. In choice c, -12/5, 7/12, and 1/9 are being multiplied by each other on both sides of the equation, but they are in different orders, hence Choice C applies the associative property of multiplication.

Which number line represents 5/4?

Answers

D because 5/4 is equal to 1 and 1/4. Since d has a number line split into fours then that is the answer. Hope this helps.

Answer:

D.

Step-by-step explanation:

Determine 5/4 as a mixed number. 5/4 as a mixed number is 1 1/4.Eliminate the answer choices that are less than 1 or greater than 2 because 1 1/4 is between 1 and 2. In this case, you can now eliminate C.Eliminate the answer choices that are greater than 1 1/2 because 1 1/4 is between 1 and 1 1/2. In this case, you can now eliminate A.With your remaining answer choices, determine the number that each number line represents. You can see that B is split into sixths and five spaces are shaded, making it 6/5. On the other hand, D is split in fourths and 5 spaces are shaded, making it 5/4.With this information, you now know that D represents 5/4 or 1 1/4 and is your answer.

I hope this helped. Comment if you have additional questions.
