Answer:
Step-by-step explanation:
Fixed monthly fee = $20
Amount charged per minute for long distance calls = $0.20
denotes total cost such that 
minutes are used for long distance calls.
Amount charged for minutes for long distance calls 
Therefore, an equation for the total cost, C, when N minutes are used for long distance calls is
1. distribute
step 1: 3 3
----- × X = ------X
5 5
3 5 3 Ima convert this into a decimal
------- × - ----- = - ------ ----> negative .375
5 8 8
2. write the problem now
3 1 7
----- X - 0.375 = ---- - X + ----
5 12 8
3. I would convert them into decimals and solve
0.6x - 0.375 = 0.08 - x + 0.875
+x +x
--------------------------------------------------
1.6x - 0.375 = 0.08 + 0.876
1.6x - 0.375 = 0.956
+0.375 +0.375
--------------------------------------------------
1.6x = 1.331
------ -------
1.6 1.6
---------------------------------------------------
x = 0.831875
rounded up : 0.83
Answer:
y=x+5
Step-by-step explanation:
Lines are parallel if they have the same slope, the Y-intercept does not matter. Since these line passes through point (0,5) it's y-intercept has to be 5 and It's still parallel with line y=x-7.
