2x - 4 = 40 so I put 4 under both of them and crossed it out
2x = 44 I got rid of the -4 on the left side
X=22 I got rid of the 2 on the left side by dividing it and making the answer for 1 x be simple and x=22
By hypothesis, each minute of local calls costs $0.05
So x minutes of local calls will cost 0.05x : You just multiply the cost of 1 minute by the total amount of minutes.
Same thing for long distances calls: Each minute costs $0.12, so y minutes of long distance calls will cost 0.12x
So to get your total charge (local calls + long distance calls), you just need to add the charges for local calls with the charges for long distance calls, which means that you need to add the expressions we got previously:
P = 0.05x + 0.12y (with P the total charge)
Hope this Helps! :)

-6m+3-n
Step-by-step explanation:
-3 x 2m = - 6m
-3 x - 1=3
Answer:
102
Step by step explanation (if non-calculator):
Times 8.5 by 10 to make 85. This'll now be 85 x 12.
If you can work this out, do so.
If not, then do 85 x 10 = 850.
Then, 85 x 2 = 170.
170 + 850 = 1020.
Now, divide 1020 by 10, since you multiplied 85 by 10 at the beginning.
1020 ÷ 10 = 102!
X=-1. Simplify both sides of the equation then isolate the variable
