Hey there! :)
Answer:

-1/5n + 7 = 2
Start by subtracting 7 from both sides:
-1/5n + 7 - (7) = 2 - (7)
-1/5n = -5
Multiply both sides by the reciprocal of -1/5, or -5.
(-5) · (-1/5n) = (-5) · (-5)
n = 25
Yeah so she spent half they year at the first one more than likely
Answer:
1 root
Step-by-step explanation:
A linear equation should only cross the x-axis at one point. That means there would only be 1 root. (Root is when y= 0)
The <em>correct answer</em> is:
The median is less than the mean.
Explanation:
This histogram is skewed right; the data "peaks" further to the left than the center.
If a histogram is skewed right, the mean is greater than the median.
This is because skewed-right data have a few large values that increase the mean but do not affect where the exact middle of the data is.
The process here is finding out the smallest number's % towards the largest number.
Divide 20 by 52:
20/52 = 0.38 (estimated) | This is the % in decimal form, which is 38%.
Conclusion: 20 is 38% of 52.

Finding the Smallest Number:
What number is 25% of 60?
Multiply 60 by the decimal form of 25%.
60 * 0.25 = 15 | 15 is 25% of 60.
Finding the Percentage. (Like what we already did.)
30 is what percent of 150?
Divide 30 by 150.
30/150 = 0.2 | 30 is 20% of 150.
Finding the Largest Number.
12 is 30% of what number?
Divide 12 by the decimal form of 30%.
12/0.3 = 40 | 12 is 30% of 40.
I hope this helps, have a great rest of your day! ^ ^
