Answer:
A. 19°
Step-by-step explanation:
To find the average of something, you add every number in the sequence and then divide it by how many numbers there are.
23 + 17 + 26 + 5 + 33 + 11 = 115
115 / 6 = 19.16666666666667
Round it down and your answer will be 19°.
Answer:
Step-by-step explanation:
1*2x+y=4
-1*2x+y=-4
-2x=-y-4
2x=y+4
x=y+4/2
0.5a - 0.3 = 5
Add 0.3 to both sides:
0.5a = 5.3
Divide both sides by 0.5:
a = 10.6
