Answer:
Solution: x = 135
Step-by-step explanation:
Hi there!
First, let´s write the equation:
√(x + 9) /4 = 3
Multiply by 4 both sides of the equation
√(x + 9) = 12
square both sides of the equation
x + 9 = 144
subtract 9 to both sides of the equation
x = 135
Let´s check the solution:
√(x + 9) /4 = 3
x = 135
√(135 + 9) /4 = 3
√(144) /4 = 3
12/4 = 3
3 = 3
Then, x = 135 is the solution to the equation.
Have a nice day!
Answer:
4.88
Step-by-step explanation:
sinA=opposite/adjacent
sin24=x/12
12(0.40673664307)=x
x=4.88083971691
Find the time it will take:
195 miles / 50 miles per hour = 3.9 hours.
1 hour = 60 minutes:
0.9 hours x 60 = 54 minutes.
3.9 hours = 3 hours and 54 minutes.
Add 3 hours and 54 minutes to the time it leaves:
3:30 pm + 3 hours = 6:30 PM
6:30 + 54 minutes = 7:24 PM
You are dividing a number (x) by three and then subtracting 1 like this. (x/3)-1
