Ok, so you want to substitute g and f in these equations so the f(x) = 2x+3x2-5 is equal to 10+6-5 or 11. The other equation is equal to 19. For the explanation put " I found this answer by substituting the given values for the variables in the equation". Your Welcome!
7+3 = 10 total marbles
1st pick = 7/10 for a red one
2nd pick = 6/9 reduces to 2/3 for a red one
3rd pick = 3/8 for a white one
7/10 x 2/3 =14/30 reduces to 7/15
7/15 x 3/8 = 21/120 reduces to 7/40
probability = 7/40

Hey there! I'm happy to help!
Let's represent each ticket with the variable t. For each ticket sold, there will be 3 dollars added to the total. So, if you multiply the number of tickets by 3, you will have your total.
This gives us the following equation.
3t=504
We could use this equation to find the number of tickets sold by dividing both sides of it by 3, which isolates the t, showing us that t=168.
Have a wonderful day!
