Answer :

The variable H as the subject of the formula is H = 2a/(B1 + B2)

What are expressions?

Expressions are mathematical statements that are represented by variables, coefficients and operators

How to make h the subject of the equation?

The equation is given as

a=H(B1+B2)/2

Multiply both sides of the equation by 2

So, we have

2a = H(B1 + B2)

Divide both sides of the equation by (B1 + B2)

H = 2a/(B1 + B2)

Hence, H as the subject of the formula is H = 2a/(B1 + B2)
