<span>x ≤ -2, where x must be less (hence the <'s wider/open side pointing to -2 while the smaller/closed side is pointing at the x. This indicates that -2 is greater than x, thus we have to find a number less than -2 to solve for x.), or equal to (hence the underbar [ _ ] that means equivalent) -2.
A) is incorrect because it's -2, and it is a solution because it is equivalent and is -2. -2 = -2.
B) is incorrect because -2.45 is farther from 0 than -2 is, thus making -2.45 less than -2. It's a solution.
C) is incorrect because -8 is farther from 0 than -2 is, so, like B, it's less than -2. Therefore it's a solution. Note that it's like the opposite with negative numbers. The greater numbers or the numbers farther from 0 equals the lesser numbers and the lesser numbers/ numbers closer to 0 equal the greater numbers. Say for instance, 100 is usually greater than 10 correct? In negative integers -100 is smaller than -10 given that -100 way farther from 0 compared to -10.
D) -1.76 is the answer, because it is closer to 0 than -2 is, thus the greater number. X cannot be higher than -2. So this is not a solution. </span>
Ron has enough time to finish his homework and walk the dog before his lesson. Ron should overestimate the total time needed. Since Ron has 50 minutes to spare he could add 25 to home work time and another 25 to walking his dog. he still ha time to do both.
