Step-by-step explanation:
7/8 - 1/2 3/4 * 5/9
8 and 2 both go into 8. Multiply straight across top and bottom.
8*1=8 7*1=7 7/8 3 * 5 = 15 4 * 9 = 36
1*4=4 2*4=8 4/8 15/36 3 can go into each.
7/8 - 4/8 = 3/8 5/12
-2.7 + (-5.2) 82 + (-24)
-2.7 - 5.2 82 - 24
-7.9 58
9 - ( -6 ) - 12 7 - 3x - 4 + x
9 + 6 - 12 Combine like terms
15 - 12 7 - 4 = 3 -3x + x = -2x
3 3 - 2x or -2x + 3
