Answer:

First mechanic worked for 10 hours and second mechanic worked for 15 hours.

Step-by-step explanation:

Let first mechanic worked for X hours and second mechanic worked for Y hours .

Now, according to the question , they worked for a total of 25 hours .

Thus ,

X + Y = 25.

Y = 25 - X   -(1)

Also, first mechanic is charging $ 95 per hour and second mechanic is charging $115 per hour .

Thus, total money charged by them will be 95X + 115Y .

Which is given to be $2675 in the question.

Thus 95X + 115Y = 2675.   -(2)

Putting equation 1 in equation 2 we get ,

95X + 2875 - 115X = 2675

20X = 200

X = 10 hours.

Thus , Y =  25 - X = 15 hours.

Thus first mechanic worked for 10 hours and second mechanic worked for 15 hours.

Given The equation -2x(-2.8)=24, we are trying to find the value of X.

The first step is to devide both sides by 2

·-x(-2.8)=12

The next step would be to distribute.

·2.8x=12

Next we devide both Sides By 2.8 to get our final answer

·X=4.28

Although your choice answers are unclear, the answer is X=4.
