This is a simple equation:)
We have to isolate "n" to be alone.
-21 = n - 8
First add 8 to both sides.
-21 = n - 8
+8 = + 8 it cancels out on the right side of the equal side and you solve on the left side
soooo
-21 + 8 = -13
-13 = n
Finally our answer is
-13 = n
When in doubt, eat a pineapple:)
Answer:
x = 54
y = 47.5
Step-by-step explanation:
If two lines p and q are parallel and line r is a transversal intersecting these lines at two different points,
(x + 56)° = (2x + 2)° [corresponding angles]
2x - x = 56 - 2
x = 54
Similarly, lines r and s are parallel lines and q is a transversal line intersecting these lines,
(y + 7)° + (3y - 17)°= 180° [Consecutive exterior angles]
4y - 10 = 180
4y = 190
y = 47.5
Multiply first then you would wanna add but you can't until you subtract 5-3 then add I got 12
Answer: He must have atleast 98 points on the next exam in order to get an average of 92 points.
Step-by-step explanation: To calculate average, you need to add all the numbers given, and divide the sum by how many numbers there are. 87 + 89 + 94 + 98 (equals 368), and divide 368 by 4. You will get the average of 92 as its result.
