Monica’s school band held a car wash to raise money for a trip to a parade in New York City. After washing 125 cars, they made $
nikklg [1K]

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.

Step-by-step explanation:

In triangle,

<u> XYZ</u> <u>PYZ</u>

XZ = PZ = 12cm

XY = PY = 5cm

YZ = YZ (Common side)

<em><u>Hence</u></em><em><u>,</u></em>

As three sides of the two triangles are equal so,

<em><u>Triangle XYZ is congruent to Triangle PYZ by SAS congruence condition </u></em>
