1. In order to make 1 salad it requires 1 head of lettuce, two tomatoes and three carrots. What would be the coefficients for the lettuce, tomatoes, and carrots assuming you wanted to make 3 salads? Write the coefficients below!

3 salad = 3 lettuce + 6 tomatoes + 9 three carrots

Coefficients: 3, 6, 9

Explanation:

1 salad = 1 lettuce + 2 tomatoes + 3 three carrots

Multiply all the coefficients of 1 salad by 3:

3(1 salad) = 3(1 lettuce + 2 tomatoes + 3 three carrots)

Expand the equation:

3 salad = 3 lettuce + 6 tomatoes + 9 three carrots

3 salad = 3 lettuce + 6 tomatoes + 9 three carrots

Coefficients: 3, 6, 9

Explanation:

1 salad = 1 lettuce + 2 tomatoes + 3 three carrots

Multiply all the coefficients of 1 salad by 3:

3(1 salad) = 3(1 lettuce + 2 tomatoes + 3 three carrots)

Expand the equation:

3 salad = 3 lettuce + 6 tomatoes + 9 three carrots

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
