178 minus 87 is 91.
ninety 87 + 91 = 178 95 + 92 + 85 = 272 178 + 272 = 450 there are five numbers so divide total by 5 450/5 = 90
You need to resubmit this so it is an equation. Could you mean 2m=m-87? If so, then follow this. subtract an m from each side: 2m-m = m-87-m simplify: m = -87 Now plug that number back in to check: 2(-87) = (-87) minus 87 -174 = -174 so it checks.
Half perimeter = 109. Subtract 87 and half the answer 22/2 = 11, this is the width. Add on the 87 giving 98, this is the length.
30% of 178= 30% * 178= 0.3 * 178= 53.4
They are: 2*89 = 178 and 1*178 = 178

There are several possible sequences such as 87 86 43 42 (subtract 1, divide by 2) - next would be 21 20 87 65 43 21 (subtract 22) - followed by (-1)
A score is 20 so four score and 7 is 87. 1863- 87 = 1776 .

-16 = m + 71 Subtract 71 from both sides: -87 = m

Well, an easy way to figure this out is divide 360 by 4 to get 90, then subtract 3 from 90 to get 87, then subtract 1 from 90 to get 89, then add 1 to 90 to get 91, then add 3 to 90 to get 93. So, the consecutive odd integers that add up to 360 are: 87, 89, 91, and 93, and to check, 87+89+91+93=360. :)
