Answer:
3x +5+2x+44+110+123+136=360
5x+418=360
c. l. t
5x=58
therefore X=11.5
Answer:
x=15º
Step-by-step explanation:
180=25+8x+5+2x
180=30+10x
180-30=10x
150=10x
15=x
Step-by-step explanation:
you would go through the origin
from 0 Go up 1 And over 1 everytime
hope this helps
Answer:66

Part A: Charlie's answer is incorrect
In step 2 of Charlie's answer he subtracted 5 from each side. Since 5x is multiplication, he must DIVIDE each side by 5 to get x by itself. The problem should have worked out like this...
Step 1: 5x = 30
Step 2: x = 30/5
Step 3: x = 6
Part B: There is only 1 solution for this problem.
