7x/8 = 21 so 7x = 21*8 x = 12*8/7 = 3*8 = 24
Because 8 x 21 = 168
If: -3*(x+8) = -21 Then: x = -1
1 x 21 = 21 2 x 21 = 42 3 x 21 = 63 4 x 21 = 84 5 x 21 = 105 6 x 21 = 126 7 x 21 = 147 8 x 21 = 168 9 x 21 = 189 10 x 21 = 210 11 x 21 = 231 12 x 21 = 252 ...
First set up a proprotion 21 over 8 = x over 100. then cross multiply to get ... 2100 = 8x , then divide both sides by 8 to get 262.5 = x
x/5 = 8/21 x = 8/21 * 5 x = 1.904761905
7x/8 = 21 so 7x = 21*8 x = 12*8/7 = 3*8 = 24
2/3 x 4/7 = 8/21Multiply across: 2 x 4 = 8, 3 x 7 = 21As 8/21 can't be simplified further the answer is 8/21
Because 8 x 21 = 168
If: -3*(x+8) = -21 Then: x = -1
1 x 21 = 21 2 x 21 = 42 3 x 21 = 63 4 x 21 = 84 5 x 21 = 105 6 x 21 = 126 7 x 21 = 147 8 x 21 = 168 9 x 21 = 189 10 x 21 = 210 11 x 21 = 231 12 x 21 = 252 ...
21 X 12 = yy X 8 = your answer.You do the math.
8 x 21 = 168
First set up a proprotion 21 over 8 = x over 100. then cross multiply to get ... 2100 = 8x , then divide both sides by 8 to get 262.5 = x
maybe eight 21 - 5 = 16 = 2 x 8
The value of x is 29
