Answer:
x = -7
Step-by-step explanation:
-6x + 3 = 45
First, we need to get rid of the 3 by subtracting it by 3. We need to do the same to the number on the other side.
-6x + 3 = 45
-3 - 3
-<em>6x = 42</em>
Then, to iolate the x, we need to divide -6 by itself to cancel the number out and get x alone. We also need to divide 42 by -6 as well.
42 divided by -6 is -7.
I hope this helps!
Answer:
<u>Sebastian is 3.8 miles away from his house.</u>
Step-by-step explanation:
4.5 - 2.4 + 1.7
2.1 + 1.7
= 3.8
- Sebastian is 3.8 miles away from his house.
Let x be the number in the problem. When it states that x is "no more than -10", it means than it is less than or equal to -10. So, we have
x≤-10
In order to cancel out the
on the left and isolate x, we multiply both sides by
(since
·
=1). Thus, we have
x≤-10·
=-15
Therefore, x≤-15
Its A or 6 because 30 divided by 5 is 6
