Brianna's family spent $134 on 2 adult tickets and 3 youth tickets at an amusement park. Max's family spent $146 on 3 adults tic
Firdavs [7]

The price of 1 youth ticket is $ 22

<em><u>Solution:</u></em>

Let "y" be the price of 1 youth ticket

Let "a" be the price of 1 adult ticket

To find: price of 1 youth ticket

<em><u>Brianna's family spent $134 on 2 adult tickets and 3 youth tickets at an amusement park</u></em>

So we can frame a equation as:

2 adult tickets x price of 1 adult ticket + 3 youth tickets x price of 1 youth ticket = 134

2 \times a + 3 \times y = 134

2a + 3y = 134 ---- eqn 1

<em><u>Max's family spent $146 on 3 adults tickets and 2 youth tickets</u></em>

So we can frame a equation as:

3 adult tickets x price of 1 adult ticket + 2 youth tickets x price of 1 youth ticket = 146

3 \times a + 2 \times y = 146

3a + 2y = 146 ----- eqn 2

<em><u>Let us solve eqn 1 and eqn 2 to find values of "y"</u></em>

Multiply eqn 1 by 3

6a + 9y = 402 ---- eqn 3

Multiply eqn 2 by 2

6a + 4y = 292 ----- eqn 4

Subtract eqn 4 from eqn 3

6a + 9y = 402

6a + 4y = 292

( - ) -------------------

5y = 110

y = 22

Thus the price of 1 youth ticket is $ 22

Thrice the sum of three fifths and two thirds less one half is what number?​
Oduvanchick [21]

Answer:

Step-by-step explanation:

Thrice the sum of three fifths and two thirds less one half  is expressed as 3(3/5 + 2/3)-1/2

Open the parenthesis

3(3/5) + 3(2/3) - 1/2

= 9/5 + 6/3 - 1/2

Find LCM

= 9(6)+10(6)-15/30

= 54+60-15/30

= 54+45/30

= 99/30

= 3 9/30

= 3 3/10

Hence the number id 3 3/10

Order the polynomial -x 4 y 2 + 7x 3 y 3 - 3xy 5 + 2x 2 y 4 in descending powers of x.
bulgar [2K]

put all the combos together first like -3xy

then the x's like -x + 7x +2x=8x

then the y's

then the whole numbers

-3xy+8x (then the y's) then the whole numbers.

I am not sure how you are writing the numbers above like -x 4 is that -x to the 4th power?

x^4 then the x^3 and so forth then the y's then the whole numbers.

Always start adding the highest x power numbers first like x^4 + 2x^4=3x^4 then work your way down. Maybe rewrite the problem please.

If 3x + 7y = 37 and x= 3, then y =
Gemiola [76]

Answer:

y = 4

Step-by-step explanation:

Given

3x + 7y = 37 ← substitute x = 3 into the equation

3(3) + 7y = 37, that is

9 + 7y = 37 ( subtract 9 from both sides )

7y = 28 ( divide both sides by 7 )

y = 4
