Answer:
x*90= your answer.
Step-by-step explanation:
X being however many test scores there are.
If you have 4 test scores, you would multiply 4*90=360
If you had 3 test scores, you would do it again, 3*90=270.
And so on. Because the test scores number wasn't listed, I provided some answers on how to solve it.
Answer:
x = 30.
Step-by-step explanation:
The angle next to the 60 degree angle = 180 - 60 = 120 degrees (adjacent angles are supplementary).
Let the angle just above 3x be y. The sum of 3x and y = 120 degrees (as opposite angles of a parallelogram are equal).
We have the following equations.
3x + y = 120............(1)
2x + 90 + y = 180
2x + y = 90.............(2)
Subtracting, (1) - (2):
x = 30.

Answer: 4.3
Step-by-step explanation:
11x2=22
22/3= 7.3
7.3-3= 4.3
