x - 7 = 8 x = 7 + 8 x = 15

The only common multiple of 7 and 8 up to 80 is 56. The multiples of 7 up to 80 are: 7 x 1 = 7 7 x 2 = 14 7 x 3 = 21 7 x 4 = 28 7 x 5 = 35 7 x 6 = 42 7 x 7 = 49 7 x 8 = 56 7 x 9 = 63 7 x 10 = 70 7 x 11 = 77 The multiples of 8 up to 80 are: 8 x 1 = 8 8 x 2 = 16 8 x 3 = 24 8 x 4 = 32 8 x 5 = 40 8 x 6 = 48 8 x 7 = 56 8 x 8 = 64 8 x 9 = 72 8 x 10 = 80

x+3/4 = 7/8 Is the same as: x+6/8 = 7/8 x = 7/8- 6/8 x = 1/8

x+8=-4

-7 +2x = x + 8 2x - x = 7 + 8 x = 15

7/8 x 8/9 = 7/9

587,878 = (5 x 105) + (8 x 104) + (7 x 103) + (8 x 102) + (7 x 101) + (8 x 100) OR (5 x 100000) + (8 x 10000) + (7 x 1000) + (8 x 100) + (7 x 10) + (8 x 1)

7 X 8 = 56

8(x - 7)

X/8-4=7 X/8=11 X=11 x 8 X=88 ;-)

If digits can't be repeated, then there are (7 x 7 x 6 x 5 x 4 x 3 x 2) = 35,280If digits can be repeated, then there are (7 x 8 x 8 x 8 x 8 x 8 x 8) = 1,835,008

8 x 7 = 56Yes. 8 x 7 = 56, and would be memorized as part of the "x 7" set of the multiplication tables. Conversely, 7 x 8 =56 and would be memorized as part of the "x 8" set of the multiplication tables.

If √x + 8 = 7, then √x = -1, so x does not exist, because √ only refers to positive roots.If √(x + 8) = 7, then x + 8 = 49 and x + 41.

Double 4 x 7 to find 8 x 7.

f(x) = 2x + 8 f(x) = -7 → 2x + 8 = -7 → 2x = -15 → x = -7½ = -7.5

1/8 x 7 is 7/8

8 x 7 = 56

We will do this in steps. -4 x -2 = 8. -7 x 7 = -49. 8 + (-49) = -41.

x+7

8 x 7 = 56 !

(7 x 8) + (8 x 8) = 15 x 8 = 120

7 x 8 = 56

-2 x -4 x -7 x -8 = 448

5 x 7 x 8 = 280
