Answer:

69 is her age

Step-by-step explanation:

Set the equation:

400 - 2x = 262

Isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 400 from both sides

400 (-400) - 2x = 262 (-400)

-2x = -138

Next, divide -2 from both sides

(-2x)/-2 = (-138)/-2

x = -138/-2

x = 69

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $22 monthly fee
vladimir2022 [97]
Company a = 22 + 0.07m
company b = 8 + 0.12m

We are looking for the time when the prices are equal. i.e. the price of company a = the price of company b

company a = company b
22 + 0.07m = 8 + 0.12m
22 - 8 = 0.12m - 0.07m
14 = 0.05m
m = 14/0.05
m = 280

Therefore, the two companies will cost the same if you talk for 280 minutes
