Two drivers begin at point C simultaneously. One drives from C to B to A. The other drives directly to A at 50 mph. How fast must the first person dirve to get to A first? A) LESS THAN 50 MPH B) LESS THAN 60 MPH C) LESS THAN 70 MPH D) MORE THAN 70 MPH

Option "D" is the correct answer to the following question.

Step-by-step explanation:

The first person drive "more than 70 mph " to get to A first.

It is given that average speed of second person is 50 mph, So to get A first , first diver must drive more than 50 mph.

So option "D" is the correct answer to the following question.

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x
