Answer:
1 3/4
Step-by-step explanation:
improper to mixed number
Answer:
Add 1 to each side
Multiply each side by 4
Take the square root of each side
Subtract 5 from each side
Combine terms
Step-by-step explanation:
1/4(x+5)^2-1=3
Add 1 to each side
1/4(x+5)^2-1+1=3+1
1/4(x+5)^2=4
Multiply each side by 4
4*1/4(x+5)^2=4*4
(x+5)^2=16
Take the square root of each side
sqrt((x+5)^2)=±sqrt(16)
x+5 = ±4
Subtract 5 from each side
x+5-5 = -5 ±4
x = -5 ±4
Combine terms
x = -5+4 x = -5-4
x = -1 x = -9
Answer:
It will take 11 minutes
Step-by-step explanation:
660 ÷ 60 = 11
Distance= rate×time
D=rt
660 (distance)= 60 (feet per minute or rate) × t (we have to find out the time it takes to get there.
We divide 660 by 60 to find the missing value, which is 11.
