The solution to this equation is the number 8
Subtract x from both sides so the answer would be; Y=-x+r
Firstly, we will let this mystery number we are finding be labelled as x. Double this number can be written as 2x. 5 less than double this number is written as 2x - 5. And because this number is between -7 and 13, we have the full inequality, -7 < 2x - 5 < 13.
To solve this inequality, we want to isolate x, so we add 5 to all 3 parts of the inequality. Doing so cancels out the - 5 in the middle, so our new inequality is -2 < 2x < 18. Now we want to divide all 3 parts of the inequality by 2 to isolate x, so now our final inequality is -1 < x < 9. Thus, we can say that x is between -1 and 9.
5/6 of a mile because 5/12+5/12=10/12 or 5/6
Do 2x60 which you'll get 120! Multiply 120 by 60, and it should be 7200 megabytes per hour!
