Make a system of equations.


Plug in 2d for 'q' in the first equation:


Multiply:

Combine like terms:

Divide 0.60 to both sides:

Now plug this into any of the two equations to find 'q':



So she has 10 dimes and 20 quarters.
The answer is B because they are alternating exterior angles
Answer:

Step-by-step explanation:

Any number raised to zero is always equal to one.
Y=15x-120
This is the linear equation. Let me know if you need me to explain
Cost of 1 ticket = $4.25
Number of tickets sold = 60
Total money incurred = 
As total money that must be earned = 340
Let the number of tickets to be sold be = x
Inequality becomes

Solving it we get, x=20
