Answer:

7. 80 miles

8. F

Step-by-step explanation:

7. Jorge leaves 2 hours early, and is going 20 miles per hour. So before Marcos starts going, Jorge has gone 40 miles (2*20). Then, 1 hour later, Jorge is at 60 miles and Marcos is at 40 (because he goes 40 miles per hour in his car). Another hour later, Jorge is at 80 (60+20) and Marcos is at 80 as well (40 + 40). They will both have gone 80 miles when Marcus catches up.

8. You want to get <em>a</em> isolated.

A = h/2(a + b)

First, multiply both sides of the equation by the reciprocal of h/2.

2A/h = a + b

Then, subtract b from both sides.

2A-b/h = a

Three times the sum of a number and seven is two less than five times the number. . a. 3x+7=5x-2. b. 3(x+7)=5x-2. c. 3(x+7)=2-5x
Nuetrik [128]
<span>We dissect each statement from the problem above to fully understand it.

the sum of a number and 7 is (x + 7)

3 times this is 3(x + 7)

is means the equal sign here </span><span>3(x + 7) = </span><span>

Two less then 5 times the number is 5x - 2.

Therefore, the answer is B, 3(x + 7) = 5x - 2</span>
