Question

Dale decides to take his 7 year old son to a ballgame. The price for the adult ticket is 15 dollars more than twice the price of the child's ticket. If you represent the price for the child's ticket using the variable "x", how would you write the algebraic expression for the adult ticket price?

30x

x + 30

2x + 15

2x + 30

Answer 1

any ideas

Answer 2

15 more than twice the child's ticket...it said that child's ticket is x so
15 more than twice x
x = 2x + 15

Answer 3

yeah i thought so. how about this 1.Translate the following phrase into an algebraic expression:
Three times the sum of x and z

3(x + z)

3x + z

x + 3z

3x + 3z

Answer 4

i believe the first one

Answer 5

okay yeah i was just making sure.
Use the distributive property to simplify the expression below:
3x-21 over 3 Or 3x-21/3

3x − 7

x − 21

x − 7

x + 7

Answer 6

i also thinkg the fist one

Answer 7

sorry for all these questions just the questions i couldn't answer for homework.
Derrick charges a flat rate of $10 for babysitting, plus an additional $4 per hour. If "h" represents the number of hours he babysits, which algebraic expression represents the total charge?

10 + 4h

10h + 4

14h

40h

Answer 8

i figured it out how about this one.
Use the distributive property to simplify the expression below:
−3(3d − 1) + 5d

−4d + 3

−4d − 3

−d + 3

−d − 3

Answer 9

The problem states to assign x to the price of the child's ticket.

then the expression for the price of adult ticket is: 2x + 15 Do not use x=2x + 15, where you are saying, "The price of the childs ticket is equal to twice the price of the child ticket + 15 dollars................see the difference. I am referring to the second response down from the top.

Answer 10

for the third problem, simplify 3x-21 would be 3(x-7)

Answer 11

For the last one, expand getting: -9d + 3 + 5d
-4d + 3
Looks like the first one don't it?
