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

Answer: 2m + 4

100% positive

⇒Since it is given that variable m should be the one to be used,

it is said that Zach is 4 years older⇒ than twice his sister Maya`s age.

⇒As indicated Maya`s age is m

⇒Twice Maya`s age is 2×m=2m

Therefore Zach`s age is 2m+4

The expression given by the given scenario is 2m+4

⇒It is the expression that can help us find the exact ages of the Zach and Maya

⇒First Option is the answer.

Exterior angle theorem.
In a triangle an exterior angle or angle outside the triangle will always equal the sum of the 2 remote Interior angle or the 2 angles not close to the outside angle.
If you look at the picture I post below the exterior angle theorem is 1+2=3 . So to find answer for your question you should write the equation p+5+p = p+50 and the p=45 degree.

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:

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.

Write an equation for the trend line shown on the scatter plot.

Answers

y=5x+15

To make an equation for this line, you need to figure out the values for the slope and the y-intercept and plug them into the formula y=mx+b

The line is going up 5 over 1 which means the slope(m) is 5

The line passes through the y intercept at 15 which means that the y-intercept(b) is 15

Correct answer y=5x+15

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.
