I think it's B and D because both of them will give you the same answer which is 2.71 but turn it into fraction.
Add, -11.5x and move it over to 8.5x
Then, subtract them together and you get 20x + 51.86 = 51.76
And you move (subtract) 51. 86 over to 51.76, subtract that and you get 20x = -0.1
Divide, and your answer is -200
Answer:
-2 hope this helps! :)
Step-by-step explanation:
-10 over 5 is -2
so a = -2
Answer is a, 57.49.
17.42-12.60-9.62= $-4.80+62.29=57.49
Divide the perimeter by 2, this will give you the sum of one length and one width.
68/2 = 34 yards
Now the length is 10 yards more, so subtract 10 from the 34 and divide by 2 again:
34 - 10 = 24
24 /2 = 12
The width is 12 yards.
The length is 12 + 10 = 22 yards.
