Pablo purchased adult and youth tickets for the football game. He bought x adult tickets for $74 each and y youth tickets for $35. Write an expression that can be used to show the total cost, C, of all tickets. BRAINLIEST
C = (74 + 35)x
C = (74 + 35)(x + y)
C = 74y + 35x
C = 74x + 35y
Answer:
C = 74x + 35y ... the last one

I'm confused, is it A or D?
Answer:
D. x>7
Step-by-step explanation:
Multiply - and -3
x+3>10
Subtract 3 on both sides
x>7
(Remember you can only switch the symbol if you divide or multiply by negative it does not apply on addition or subtraction)
Hope this helps!
Answer:
It is D.
Step-by-step explanation:
Remove parentheses: x + 3 > 10
Subtract 3 from both sides: x > 10 - 3
Simplify 10 - 3 to 7: x > 7

Rapid Rental Car charges a $40 rental fee, $25 for gas, and $0.65 per mile driven. For the same car, Capital
Cars charges $55 for rental and gas and $0.75 per mile.
Part 1 out of 2
For how many miles is the rental cost at both companies the same?
The rental costs at both companies are the same at
miles.
40 + 15 + 0.25x = 45 + 0.35y
Solution
55 + 0.25x = 45 + 0.35y The only way you can do this is to assume that x and y are equal
subtract 45 from both sides
55 - 45 + 0.25x = 0.35x
10 + 0.25x = 0.35x Subtract 0.25x from both sides.
10 = 0.35x - 0.25x
10 = 0.1x Divide by 0.1
10/0.1 = x
x = 100 So if each car goes 100 miles, it should turn out to be the same no matter which company gets the rental.
Let's see if that is true.
Cost for the first company = 40 + 15 + 0.25x = 55 + 25 = 80 dollars.
Cost for the second company = 45 + 0.35x = 45 + 35 = 80 dollars.
Conclusion
Both rentals charge the same total amount when each car is driven 100 miles.
The charge is 80 dollars.
Hope this helped! :)
John paid $50 for renting a cycle for 5 hours. Which graph shows the relationship between the cost of renting a cycle for different hours?
Photos go from A to D. I'm guessing it's A but I still want to check.
Answer:
Step-by-step explanation:
You are correct. It is A
The cost is 10 dollars an hour. As the hours increase, so does the cost.

how to graph x<-28 on a number line
Draw out a number line. Make sure -28 is on the number line, along with other optional values (such as 0 perhaps). At -28, plot an open circle or hole. This indicates this value is not part of the solution set. This is because there is no "or equal to" as part of the inequality sign. Then shade to the left to indicate values smaller than -28.
So in summary, you'll have an open hole at -28 and shading to the left.

Write the algebraic expression that is represented by the model
Answer:
3x > 2y
Step-by-step explanation:
I'm not sure if this answer is correct, so I'm sorry if you get it wrong. There are 3 x blocks, so you that's how you get 3x. There are 2 y blocks, so that's how you get 2y. The y blocks look smaller/less than the x ones, so I said that 3x is greater than 2y.
