For example:
Find: (3-i)+(2+3i) by graphing
Step 1: Graph 3-i and 2+3i on the complex plane. Connect each of these numbers to the origin with a line segment.
First, find the price per cake
30/10 = 3
now just multiply!
3(25) = 75
the answer is $75
Answer: sry just trying to get points
Step-by-step explanation:
B+ p= 10.40
b=2x 2.50
Now using substitution method replace b in first equation with value of second equation basically combing the two equations into one do you end up with one variable to solve .
2 x 2.50 +p =10.40
5 + p=10.40
P=$5.40
b =$5.00
The answer is EACH pendant cost $2.70
(You have to divide 5.40 by two )
