x=10 100x-89x=110 11x=110 x=10
100x - 89x = 110 ∴11x = 110 ∴x = 10 In more detailed explanation; The first line means "100 times x minus 89 times x equals 110" We can apply the distributive rule here. Both "100x" and "89x" are divisible by x. This means we can factor it out of both terms giving us the expression: x (100 - 89) = 110 We can then subtract 89 from 100, giving us: x(11) = 110 or: 11x = 110 Finally, both sides are divisible by 11, so we can divide it from both sides, giving us: x = 10
ANSWER: 89xeighty nine times a number= 89 * x= 89x
Oh, dude, let's break it down. So, if x equals 6 and y equals 8, we just plug those values into the expression. 9 times 6 is 54, and 10 times 8 is 80. Add those up, and you get 134. Ta-da!
