Step-by-step explanation:
x/11-5= -2
Make x the subject and carry over the -5 to the -2.
x/11= -2+5
x/11= 3
Carry over the 11 to the 3 and make x the subject.
x= 3*11
x= 33
To see of the answer is correct, replace the x with the value it is in brackets. The value of x is 33.
(33)/11-5= - 2
3-5= - 2
Therefore x is 33 and its correct

Step-by-step explanation:
Raul took 2 hours and 30 mins to bike 31 1/4 miles. Well 31 1/4 is equivalent to 31.25 and 2hr 30mins is equivalent to 2.5. Now we need to divide the distance by the time to get the rate in mph. 31.25/2.5 = 12.5 So Raul rode at 12.5 miles per hour.
Area of four walls + area of ceiling = 2h(l+b) + lb
=2*2.7(6.8+3.5) +6.8*3.5
=2*2.7*10.3+ 23.8
= 55.62+23.8
=79.42
Cost of plastering =79.42*12
= 953.04
