Well, according to thedinosaurmuseum.com, the fastest ever running dinosaur(s) could run to up to (approx.) 60 km an hour. And according to sciencenetlinks.com, T. rex's ran approx. 45 miles an hour. To be able to subtract, you would have to find out how many kilometers in a mile. There are 1.60934 kilometers in a mile (round it to 1.6). So that means that a mile is slightly larger than a kilometer. Now you have to multiply 60 km by 1.6. Once you do that, subtract that number by 45. And there is your answer! I hope this has helped!

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.
