The answer to your problem would be 400 because to find the answer you need to multiply 120 by .3 to get the answer because 3 % means per 100 and that is why you make it .3 hope i help.
77/8= 9.625 and 31/4= 7.75...so 9.625-7.75= 1.875
The final answer is:
y - 34 = x2 - 12x

Given that the perimeter is 16ft and width is 5 ft,

Distribute 2:

Take away 10 from both sides:

Evaluate the right hand side:

Divide by 2 on both sides:

22. 36
23. 13/2
24. 1.1, -9.1
