Question

Find the value of b/2a+b, when a=5 and b=-2​

Answer 1

Answer:

• -11/5 or -1/4

Step-by-step explanation:

There are two possibilities in this question.

________________________________________________

Possibility No. 1

Given:

• b/2a + b
• b = -2
• a = 5

Step-1: Substitute the values given into the equation.

• b/2a + b
• => -2/2(5) + (-2)

Step-2: Solve.

• => -2/10 - 2
• => -1/5 - 2
• => -11/5

Hence, the solution for possibility No. 1 is -11/5.

________________________________________________

Possibility No. 2

Given:

• b/2a + b
• b = -2
• a = 5

Step-1: Substitute the values given into the equation.

• b/2a+b
• => -2/2(5)+(-2)
• => -2/10 - 2
• => -2/8
• => -1/4

Hence, the solution for possibility No. 2 is -1/4.

Answer 2

Answer:

$-\frac{1}{4}$ or -0.25

Step-by-step explanation:

$\frac{b}{2a+b}$

Plug in a=5 and b=-2

$\frac{-2}{2(5)+(-2)}$=

$\frac{-2}{10-2}$=

$\frac{-2}{8}$=

$-\frac{1}{4}$ or -0.25

Have a nice day! :)
