Answer:

e = 6

Step-by-step explanation:

10e - 2e - 9 = 39

8e - 9 = 39

8e = 48

e = 6

CHECK:

10(6) - 2(6) - 9 = 39

60 - 12 - 9 = 39

39 = 39

Andrew participated in a bicycle race. The total distance covered was 56

Inessa05 [86]

(B) 4 hr is the correct answer.

<h3>Explanation :</h3>

★ Speed of body is defined as the ratio of distance travelled to the time taken $.$

speed = distance/time

Given that,

distance = 56 miles

speed = 14 miles per hour

By substituting the values, we get

⭆ time = distance/speed

⭆ time = 56/14

⭆ time = 4 hr

HOTS... Just solve this questions

AfilCa [17]

Answer:

Step-by-step explanation:

8. B is the midpoint of AD

A (x,y)

D( -1,3) B ( (x-1)/2, (y+3)/2) and B ( 1,1)

then (x-1)/2=1, x-1=2 ( +1) , x= 2+1, x=3

(y+3)/2=1, y+3=2 ( -3) y=2-3, y= -1

then A (3, -1)

9. (-8,3)

(s,3) the midpoint (0,u)

then (s-8)/2=0, s=8

(3+3)/2=u, u=6/2, u= 3

10. a=1 ( the y coordinate is the same as the midpoint

A(3,1)

B(x,y) the midpoint (5,1)

(3+x)/2=5, 3+x=10 , x=10-3, x=7

(y+1)/2=1, y+1=2,y=2-1, y=1

B(7,1)
