Answer:
Obtuse because it bigger than an acute and a right angle
Answer:
Step-by-step explanation:
We have two fractions and are being asked to subtract them.
7/8 and 1/3 don't have the same denominator, so to do as so, we need to find the LCM of both denominators, multiply them to that, and do the same for the numerators.
So what is the LCM (Least Common Multiple) of 8 and 3?
24.
Therefore :
The coordinates of B would be C. (4, -8)
I got this because when reflecting over the x axis, the only value that changes is the y value. If you graph it out, the y value is the opposite while the x is the same.
Hope this helps!
a. 6/22 or 27.27% b. 3/22 or 13.63%
there are 22 days in the range from March 18th till March 30th. each day has a probability of 1/22. add all the days together in a range to find the probability of each. A. 25,26,27,28,29,30 is 6/22 dates. B. 18,19,20 is 3/22.

Steps:
I will solve your system by substitution.
(You can also solve this system by elimination.)
