16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11
The answer is 109. 21 + (1 x 28) = 49 22 + (2 x 28) = 78 25 + (3 x 28) = 109
39. 78 = 2 x 3 x 13 117 = 32 x 13 156 = 22 x 3 x 13 gcf = 3 x 13 = 39
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
78 = 2 x 39 = 2 x 3 x 13 128 = 2 x 64 = 22 x 32 = 23 x 16 = 24 x 8 = 25 x 4 = 27 GCF = 2
16x - 8x + 12 = 78 + 22 or simplified to (16x-8x=8x)(78+22=100) 8x + 12 = 100 Simplify some more (Subtract 12 from both sides) 8x = 88 Divide both sides by 8, and x = 11
x = 78 Equation: x/100 = 78% Solution: x/100 = 78% x/100 = 0.78 x = 0.78 * 100 x = 78
The highest common factor (HCF) of 78, 156, and 169 is 13.
22 x 3 x 7 = 84
x/78 Whatever x equals, divide it by 78.
