Imagine a number line. 0 is the start and it either goes to the right which is higher or to the left which is lower. -13 goes to the left since all negative numbers are at the left of 0. So you basically count up from -13 which is -12,-11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1, and 0. We just went 13 places up, so only 7 more to go. Counting up from 0 seven places is 7. So the answer is seven. Keep practicing and it will get easier and make sense.

What is -11+6x+25-3x
evablogger [386]

Answer:

3 x + 14

Step-by-step explanation:

Simplify the following:

6 x - 3 x - 11 + 25

Grouping like terms, 6 x - 3 x - 11 + 25 = (6 x - 3 x) + (-11 + 25):

(6 x - 3 x) + (-11 + 25)

6 x - 3 x = 3 x:

3 x + (-11 + 25)

25 - 11 = 14:

Answer:  3 x + 14
