Mathematics

Elena L [17]3 years ago
7 0

Answer:

{(-34/7, -16/7)}

Step-by-step explanation:

Rearrange values, multiply to solve for x.

(5) 2y = 3x + 10

(-2) 5y = 4x + 8

Solve for x.

10y = 15x + 50 ↓

-10y = -8x -16

Combine and evaluate.

0 = 7x + 34

Subtract 34 from both sides.

7x = -34

Divide both sides by 7.

x = \frac{-34}{7}

Plugin x value into either equation to solve for y.

2y = (3 × \frac{-34}{7}) + 10

2y = \frac{-102}{7} + 10

2y = \frac{-32}{7}

y = \frac{-16}{7}

instead of P+2x = y it should be P-2x=y

 so then it is P-2x/2 =y

Haynes High School chartered buses for 60 students to go on a field trip. Valley High School chartered buses for 80 students.
Svetradugi [14.3K]

Answer: $20

Step-by-step explanation:

Let 'x' be the cost of a ticket at Haynes

Let 'y' be the cost of a ticket at Valley

Since the total cost from both schools are the same, we can write it as:

60x=80y

Since the cost of tickets at Valley was $5 less than Haynes, we can write it as:

y=x-5

Now we have two equations, we can use to substitute into the other expression:

60x=80y

60x=80(x-5) we substitute y in this equation with the other equation

60x=80x-400

-20x =-400

x = 20

Therefore the cost of the ticket at Haynes is $20 and the cost of the ticket at Valley is $15.

How many solutions does the following system of equations have?<br> 2y= 5x + 4<br> 1 = 3x + 2
Elden [556K]

Looks like a pretty regular system, no parallel lines.  In fact the second equation is a vertical line as written; not sure if that's a typo.  Either way,

The square root of 2 is irrational. Because 2 is not a perfect square therefore the square root of 2 must be irrational. 1.4 is its approximate to the tenths place. I hope this was helpful

What’s the quotient of 2 1/4 and 5/8
lions [1.4K]

Answer:

The correct result would be 3 3/5.

Step-by-step explanation:

If you would like to find the quotient of 2 1/4 and 5/8, you can calculate this using the following steps:

2 1/4 = 9/4

2 1/4 / 5/8 = 9/4 / 5/8 = 9/4 * 8/5 = 18/5 = 3 3/5
