28 + 28 = 56
The answer is 56
Their sum is 56.
56 * 308 the same-no.
Set up the equation and solve for z: 28 + z = 56 (next, subtract 28 from each side of the equaition to solve) z = 28
2/8 + 3/7 = 1/4 + 3/7 = 7/28 + 12/28 =19/28
15x2 + 2x - 56 = 15x2 + 30x - 28x - 56 = 15x(x + 2) - 28(x + 2) = (15x - 28)(x + 2)
(7x4) + (4x7) = 28 + 28 = 56
The least common denominator of 7, 8, and 2 is 56. 4/7 = 32/56 1/8 = 7/56 1/2 = 28/56 4/7 + 1/8 + 1/2 = 32/56 + 7/56 + 28/56 = 67/56 = 1 11/56 one and eleven fifty-sixths
If that's -56 + 28, the answer is -28. If that's -56/28, the answer is -2. If that's -56 x 28, the answer is -1568. It's probably not -56 - 28, but if it is, the answer is -84.
Yes, 28 is a factor of 56, because 56/28 is a whole number.
