Answer:
p = 12
Step-by-step explanation:
add 2 to both sides of the equation
24 = 2p ( divide both sides by 2 )
p = 12
Answer: p=2
Step-by-step explanation:
22=2p-2
You add two to 22 which will give you 24
24=2p
You want to divide the 2 to get the letter by itself
12=2

Cell carrier 1
0.15 per minute (0.15m)
$26.50 first, and then add on for every minute
cost carrier 1 = 0.15m + 26.50
carrier 2
0.25 per minute (0.25m)
$14.50 first, and then add on for every minute.
cost carrier 2 = 0.25m + 14.50
to find out when they cost the same, make the two costs equal to each other:
0.15m + 26.50 = 0.25m + 14.50
all that's left is to solve for m
0.15m + 26.50 = 0.25m + 14.50
subtract both sides by 0.15 m
26.50 = 0.2m + 14.50
subtract both sides by 14.50
12 = 0.1 m
divide both sides by 0.1
m = 120
the phone carriers will have the same cost at 120 minutes
(1) $26.50 + $0.15m
(2) $14.50 + $0.25m
Set the two equations equal to each other and solve for m minutes . . .
26.50 + 0.15m = 14.50 + 0.25m
26.50 - 14.50 = 0.25m - 0.15m
12.00 = (0.25 - 0.15)m
12 = 0.10m
m = 12/0.10 = 120
m = 120 minutes

80/100 = 76/x from this point you cross multiply which gives you 80x = 76(100) you multiply 76 by 100 and get 7600 so then the equation look like this 80x = 7600 then divide by 80 on both sides and get the answer of x = 95 which is basically your answer I hope this helps :)
80 percent of the number 95 is 76.
We have,
Let the number = M
80% can be written as.
= 80/100
= 0.8
Now,
0.8 x M = 76
Solve for M.
0.8 x M = 76
M = 76/0.8
M = 760/8
M = 95
Thus,
80 percent of the number 95 is 76.
