Step-by-step explanation:
Answer:
3.65, because 14.60 divided by 4 is 3.65
Step-by-step explanation:
I am guessing your problem should read...
A) n = -5n + 90 (isolate the variables by adding 5n to each side)
+5n +5n
6n = 90 (since we don't want to know what 6n's are worth, divide by 6)
6n/6 = 90/6
n = 15
Find the difference of A and M
(3,5.5)-(-1,8)=(4,-2.5)
Doubly the difference (8,-5)
And add on to A
(-1,8) +(8,-5)=(7,3)
B is at (7,3)
