A student was asked to use the formula for the perimeter of a rectangle, P = 2l + 2w, to solve for l. The student came up with a
Ainat [17]
Although the student in the example used in this question did not make too many errors, there is a better way of working out this equation so that you will find the correct answer. In an equation like this where you need to get I on it's own, you need to divide everything by two to get -w+P over 2 = l. To get to this point, to start with you would need to do -2w+P=2l instead of P-2w=2l.

Start at the origin. Move 2 units right and 8 units up. What is the ordered pair for this point? pls help ASAP​
Digiron [165]

Answer: (2,8)

Step-by-step explanation:

The origin is the point (0,0), so when you move two units right you land on the x-value of 2. From there you then add 8 units, putting you at the y-value of 8. Therefore, you end with the point (2,8) after this translation.

The system of linear equations represents the situation is;

x + y = 125

x + y = 1255x + 8y = 775

<h3>Simultaneous equation</h3>

Simultaneous equation is an equation in two unknown values are being solved for at the same time.

let

  • number of quick washes = x
  • number of premium washes = y

x + y = 125

5x + 8y = 775

From equation (1)

x = 125 - y

5x + 8y = 775

5(125 - y) + 8y = 775

625 - 5y + 8y = 775

- 5y + 8y = 775 - 625

3y = 150

y = 150/3

y = 50

  • Substitute y = 50 into

x + y = 125

x + 50 = 125

x = 125 - 50

x = 75

Therefore, the number of quick washes and premium washes Monica’s school band had is 75 and 50 respectively.
