The average of 4 numbers is 10. If each of the four numbers is increased by 8, what is the average of the 4 new numbers?

A.) 8
B.) 10
C.) 12
D.) 14
E.) 18

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

b.-4 units

all you   do is count how many times you move

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
