a carnival sold tickets for $1.50 for adults and $1.00 for students. there were 54 tickets sold for a total of $70.50. write a system of equations to represent the number of adult tickets,x, and the number of student tickets,y. find the solution and explain what it means. I'll help you if you help me

Answers

Answer:

The number of adult tickets are 33 and the number of student tickets are 21 .

Step-by-step explanation:

As

The number of adult tickets x  and the number of student tickets y.

As given

A carnival sold tickets for $1.50 for adults and $1.00 for students.

There were 54 tickets sold for a total of $70.50.

Equations becomes

x + y = 54

1.50x + 1.00y = 54 × 70.50

Simplify the above

(150x)/(100) + (100y)/(100) = (7050)/(100)

150x + 100y =7050

Two equations are

x + y = 54

150x + 100y =7050

Multiply x + y = 54 by 150 from 150x + 100y =7050

150x - 150x + 100y - 150y = 7050 - 8100

-50y = -1050

50y = 1050

y = (1050)/(50)

y = 21

Putting the value of y in the equation .

x + 21 = 54

x = 54 - 21

x = 33

Therefore the number of adult tickets are 33 and the number of student tickets are 21 .

How do u do this step by step

Answers

You need to use PEMDAS or the Order of Operation. P is parentheses, E is exponents, M is multiplication, D is division, A is addition, and S is subtraction. 8+5 is 13. There are No exponents or multiplication. Divide 13 by 1 and you get 13. So far, you have 1 + 13 - 3 - 13 + 4. If you do the addition you get 18 - 3 -13. 18 - 3 is 15. 15 - 13 is 2. Your answer is 2.

Hi I really need help with this question. SHOW YOUR WORK IF YOU ARE WILLING TO HELP ME TY! <3 (4.5+7.6)-8/2.5

Answers

Answer:

8.9

Step-by-step explanation:

Parenthesis are always first so,

4.5+7.6=12.1

so the problem would look like this now:

12.1-8/2.5

so convert 8/2.5 to 8÷1/5÷2 so this will become 16/5

16.5 concerted to decimal=3.2

so 12.1-3.2=8.9
