Answer:
B. 121
Step-by-step explanation:
Complete the square.
Take half of the middle term, 22, and square it.
So 11^2 = 121.
Let the speed of the joker initially be x mi/hr
after reduction, the new speed will be: (x-1) mi/hr
but
time=(distance)/(speed)
hence :
Total time taken will be:
4/x+5/(x+1)=41/20
solving for x we get:
x=21.585 mi/hr
thus the initial speed was 21.585 mi/hr after reduction the new speed was 20.585 mi/hr
Answer:
q = -26
Step-by-step explanation:
Set up an equation where q is the unknown number:
q + 11 = -15
Solve for q by subtracting 11 from both sides:
q + 11 = -15
q = -26
C
Because 1 km is 1,000 meters so you were just multiply 1000 by 10 and get 10,000
