Monica purchased adult and youth tickets for the fair. She bought x adult tickets for $28 each and y youth tickets for $15. Write an expression that can be used to show the total cost, C, of all tickets.

C = (28 + 15)x
C = (28 + 15)(x + y)
C = 28x + 15y
C = 28y + 15x

Answer 2

please help me @DanJS your my only hope

Answer 3

These are kinda awkward.
Judging by the answers for the first one, this is the expression in the problem.

\[\frac{ 1 }{ 5m-20 }\]

Factor a 5 out in the denominator

Answer 4

but do you know what its equivalent to i got 150

Answer 5

not for what its equivalent to
but in the options

Answer 6

It doesn't have a single value. There is a variable in the expression. All you can do is alter it or simplify.
Are the problems actually written out in english like this? It is difficult to tell what is numerator , denominator, or quantities. I can tell because of the multiple choices, but it is not clear from the problem.

Answer 7

\[\frac{ 1 }{ 5m-20 } = \frac{ 1 }{ 5(m-4) }\]

Answer 8

For the second...
\[\frac{ 3(3y+15) }{ 5 }\]

The(3y+5) i am assuming is in the numerator, by what the answers are.
factor a 3 out of the parenthesis in this one.

Answer 9

which one is this for

Answer 10

The perimeter of the triangle, is the sum of the 3 given sides. Add up like terms.

Answer 11
