Question

What equation demonstrates 1/2a + 2/3b=50 when b equals 30?

a. 1/2a + 2/3(30)=50
b. 1/2a + 20 = 50
c. 1/2a = 30
d. a/2 = 30

Answer 1

To solve the equation 1/2a + 2/3b = 50 when b equals 30, substitute the value of b into the equation. Simplify the equation to find the correct equation.

Step-by-step explanation:

To solve the equation 1/2a + 2/3b = 50 when b equals 30, we substitute the value of b into the equation.

So, the correct equation is:

• 1/2a + 2/3(30) = 50

Simplifying the equation, we get:

• 1/2a + 20 = 50

Therefore, the correct equation demonstrating the given condition is 1/2a + 20 = 50.
