78 x 21 is 1638.
-21, -20, -19, and -18 While that is correct it would be better to show how to get the answer. the 4 consecutive integers would be represented by x, x+1, x+2, x+3 now the sum would be -78 so you have x+x+1+x+2+x+3=-78 Reduce and solve for x 4x+6=-78 4x=-84 x=-21 so, x=-21 then x+1 = -20, x+2 = -19 and x+3=-18
The answer is 109. 21 + (1 x 28) = 49 22 + (2 x 28) = 78 25 + (3 x 28) = 109
21% of 78 is 16.38
78 - 21 = 57
1 x 78 = 78 2 x 78 = 156 3 x 78 = 234 4 x 78 = 312 5 x 78 = 390 6 x 78 = 468 7 x 78 = 546 8 x 78 = 624 9 x 78 = 702 10 x 78 = 780 11 x 78 = 858 12 x 78 = 936
x = 78 Equation: x/100 = 78% Solution: x/100 = 78% x/100 = 0.78 x = 0.78 * 100 x = 78
x/78 Whatever x equals, divide it by 78.
18= (x%)(78) 18/78 = x% .230769 = x 23.0769% ---------------------------------------- or (18/78) * 100
