7 5/21 I think that would be the one that can cover it but not have to much left.
You might need a second opinion.
Answer:
<em>n = 6 </em>
Step-by-step explanation:
2.3 ×
= (1 × 10³)(2.3 ×
)
(1 × 10³)(2.3 ×
) = (1)(2.3) × (10³)(
) = 2.3 ×
2.3 ×
= 2.3 ×
⇒ 3 + n = 9 ⇒ <em>n = 6</em>
Answer:

Step-by-step explanation:
1. The initial equation given to us is
. Rearranging the equation to isolate
, we have:

2. Using the equation we rearranged in part 1, we can substitute given values:

3. We see from our equation in part 1 (
) that when
, the denominator of our fraction will be equal to 0. Since we cannot divide by 0, the velocity remains undefined and cannot be determined.
6a+16
Explanation:
If there's just a variable, there's an understood 1 in front of it. So what that really says is:
7a-1a+16
So, you combine the a's. 7a minus 1a is 6a. Same as 7-1,but you have a variable stuck on the end of it.
6a+16

This is what i got:
-x-20=6x+1
