Step-by-step explanation:
a. x = 30° (180-70-80)
b. <FGA = 80°
c. vertical angles
Answer:
add 64 to both sides
Step-by-step explanation:
x = -26.3
About 11% - I first subtracted 250 from 282, to get 32. I then did 32/282 to get .11.... You round that out to about 11%
For this case, the first thing we are going to do is assume that all the tests are worth the same.
Then, we define a variable:
x: score of Mona's last test
We write now the inequality that models the problem:

From here, we clear the value of x:
Answer:
the lowest grade that Mona can get for her last test so that her test average is 90 or more is:
x = 87
