Move constant over (5x=38+2), combine terms (5x=40), divide both sides by 5 (x=8)
Answer:
c

Answer:
Fastest to slowest = 6.08 > 6.4 > 6.72 > 6.75 > 7.03
Step-by-step explanation:
The person who completes the 50-meter race within the shortest possible time is the fastest sprinter. Here, the third sprinter crossed the line in 6.08 seconds, whereas the 4th sprinter crossed the line in 7.03 seconds. That is why the third sprinter has won the race, and he becomes the fastest. On the contrary, the fourth person takes the most time to complete the race, meaning he is the slowest.
Answer:

Step-by-step explanation:
<u><em>The complete question in the attached figure</em></u>
<em>Verify each case</em>
Part 1) we have

solve for x




Part 2) we have

Multiply both sides by -1 and rearrange the terms on the left side to get

This expression is the same that the expression in Part 1)
That means, that the equations Part 1) and Part 2) are equivalent
therefore

Part 3) we have

Remember that

This expression is the same that the expression in Part 1)
That means, that the equations Part 1) and Part 3) are equivalent
therefore

Part 4) we have

This equation is not equivalent to the other three, because some terms are multiplied by -8/7 and others are not. When different things are done on either side of the equal sign, it changes the equation, resulting in a different solution
