Answer 1

@green_1 can you help me please

Answer 2

Hello, Raven! Which methods of solving systems of linear equations have you used before?

Answer 3

Which system of equations can be used to solve the following problem?

Each child ticket for a ride costs $3, while each adult ticket costs $5. If the ride collected a total of $150, and 40 tickets were sold, how many of each type of ticket were sold? Let c be the number of child tickets and a be the number of adult tickets.


A. 3a + 5c = 40
a + c = 150

B. 5c +3a =150
c + a = 40

C. 3c + 5a = 150
a + c = 40

D. 3c + 5a = 40
a + c =150

Answer 4

I'd suggest you choose the method most familiar to y ou and then apply it to this particular problem.

Answer 5

that doesn't help me

Answer 6

You have 2 different problems posted. Which do you want to focus on?

Answer 7

the second one the first was answered but the person who answered it deleted their reply

Answer 8

I am trying to find out what you already know. I assume you've solved systems of linear equations before, so that we could use an approach familiar to you to solve the problem at hand.

Answer 9

Among the methods you've probably studied so far are: substution, elimination by addition/subtraction, and graphing. Whic shall we apply to the problem at hand?

Answer 10

can someone else help me?

Answer 11

I stand by the question I've asked y ou: which methods of solving systems of equations have y ou used before? I do that so as to build our discussion on something familiar to you.

Answer 12

If x+y=5,
and if 2x-y = 6, the substitution method could be easiest . Solve the 2nd equation for y. Then substitute your expression for y into the first equation.

Answer 13

i'm just getting confused because i have studied a lot but i am behind in class and i forgot how to do it

Answer 14

I'm sorry about that, but that's no excuse for not getting personally involved in solving this problem. Can you do the problem I typed in immediately above, using the substitution method?

Answer 15

did you read the problem? that is not in it at all

Answer 16

The problem I posted was an EXAMPLE posted for the purpose of illustrating the substitution method.
If x+y=5,
and if 2x-y = 6, the substitution method could be easiest . Solve the 2nd equation for y. Then substitute your expression for y into the first equation.

the 2nd equation, 2x-y=6, can be solved for y. y=2x-6.

Substitute (2x-6) for y in the first equation. What do you obtain?
