Answer:

m=mary age

j=joe age

m=2j-10

m-j=30

rewrite

m=2j-10

m=j+30

so that means that

2j-10=j+30

-j

j-10=30

+10

j=40 so lets plug this in

m=2(40)-10

m=70

Hope This Helps!!!

the utility bill for the Millers home was it in April with $132 42% of the bill was for gas and the rest for electricity how muc
Anit [1.1K]
In the given question, there are several data of immense importance. based on these data's the answer to the question can be easily deduced. it is already given that the total utility bill for the month of April in Millers house is $132 and 42% of the bill was paid for gas. remaining amount is paid as electricity charges.
Now
Amount of money paid for gas = 132 * (42/100) dollars
                                                  = 5544/100 dollars
                                                   = 55.44 dollars
Then
The amount of money paid for electricity = (132 - 55.44) dollars
                                                                   = 76.56 dollars
So the Millers paid 55.44 dollars for gas and 76.56 dollars for electricity in the month of April.

The table shown below shows some values for functions f(x) and g(x). What is/are the solution(s) to f(x)=g(x)? Explain your answ
aleksandr82 [10.1K]

Answer: x = -1 and x = 1

Step-by-step explanation:

The solution to f(x) = g(x) is the point at which the two intersect , that is , the point at which they are equal. Checking through the table given ,it is only 9 and 12 that is common to both f(x) and g(x) .

Therefore : the solution to f(x) = g(x) is the point where x = -1 and x = 1
