A proportional relationship is used to illustrate linear equations.

The constant of proportionality is 3

From the table, we have the following points:

(x,y) = (2,6) (3,9)

The constant of proportionality is calculated using:

\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}

So, we have:

\mathbf{m = \frac{9-6}{3-2}}

Subtract

\mathbf{m = \frac{3}{1}}

Divide

\mathbf{m = 3}

Hence, the constant of proportionality is 3

Suppose a lab need to need to make 400 liters of 39% acid solution, but the only solutions available to the lab are 20% acid and
Maslowich

Answer:

c + d = 400

0.2c + 0.5d = 156

Step-by-step explanation:

Let

c = number of liters of 20% acid solution

d = number of liters of 50% acid solution.

c + d = 400 (1)

0.2c + 0.5d = 400(0.39)

0.2c + 0.5d = 156 (2)

From (1)

c = 400 - d

Substitute c = 400 - d into (2)

0.2c + 0.5d = 156 (2)

0.2(400 - d) + 0.5d = 156

80 - 0.2d + 0.5d = 156

- 0.2d + 0.5d = 156 - 80

0.3d = 76

d = 76/0.3

d = 253.33 liters

Substitute d = 253.33 into (1)

c + d = 400

c + 253.33 = 400

c = 400 - 253.33

c = 146.67 liters
