The answer is
because you subtract exponents
Answer:
So we can first use the distance formula which is for 2 dimensional but seen as we're in 1 dimensions we dont have to use it. So we can just get the distance between them using a formula I made -
|a-d| = distance
So if we use that formula we can get that -7-(-2) = -7+2 = -5. Then take the absolute value which is 5.
Therefore the answer is
<h2><u>
5 is answer</u></h2>
Answer:
B. 20
Step-by-step explanation:
x + 40 = 3x
x - x + 40 = 3x - x
40 = 2x
20 = x
First, convert to improper fractions, which are easier to use for us:
16/7-4/3
Convert to a common denominator of 21:
48/21-28/21
Finally, subtract to get:
20/21
