Divide both sides by -5
You would then get (square root)x=3 since the negatives would cancel out
Then you square both sides
You will be left with (x)*2=(3)*2
Your answer will be C. X=9
Hope that helped!
Answer:

Step-by-step explanation:
Given,
Leaning Tower of Pisa is shifted, P = 13.5 ft
Height of Leaning Tower of Pisa, B = 186 ft
Now, degree of tilt of the tower from vertical




Hence, angle of tilt is equal to 
1 1/2 hours before 12:00 am, which is half an hour before 11:00 pm, which is 10:30 pm
Answer:
x=1, y=4
Step-by-step explanation:
x+y=5 - (1)
y=3x + 1 (2)
Sub (2) into (1)
x + (3x +1)=5
4x=5-1
x=4 ÷4
=1
Sub x=1 into (2)
y=3(1)+1
= 4
