If a is directly proportional to b, and a = 25 when b = 35, find b when a = 40

koban [17]

If a is directly proportional to b, we have the relationship to be:

$\begin{gathered} a\propto b \\ \therefore \\ a=kb \\ where \\ b=constant \end{gathered}$

When a = 25, b = 35. Therefore, we can calculate the value of k as follows:

$\begin{gathered} 25=35k \\ k=\frac{25}{35} \\ k=\frac{5}{7} \end{gathered}$

Therefore, the relationship is given to be:

$a=\frac{5}{7}b$

When a = 40, we can calculate the value of b to be:

$\begin{gathered} 40=\frac{5}{7}b \\ 40\times7=5b \\ 5b=280 \\ b=\frac{280}{5} \\ b=56 \end{gathered}$

The value of b is 56.

Suppose y varies directly with x, and y = 12 when x = 2. What direct variation

neonofarm [45]

Answer:

$y=24$

Step-by-step explanation:

Given:

$y=kx$

Substitute:

$\left \{ {{y=12} \atop {x=2}} \right.$ into $y=kx$

$12=k\times2$

Swap the sides:

$k\times2=12$

Divide both sides of the equation by the coefficient of variable:

$k=\frac{12}{2}$

Cross out the common factor:

$k=6$

Find the equation of the function:

$y=6x$

Substitute:

$y=6\times4$

Calculate the product or quotient:

$y=24$

What value of w is a solution to this equation? w/2 = 6 w = 10 or w = 12

Monica [59]

W=12 would be the correct answer. I got this because if you divided 12 by 2, (12/2) you would get 6!
