Question

a = 5b + 8 rearrange the formula to make b the subject

Answer 1

Answer:

b=(a-8)/5

Step-by-step explanation:

we have given the equation a= 5b+8

First step we will do is to shift 8 on left hand side of the equation positive 8 will become negative 8after shifting the equation will become a-8=5b

Next we will shift 5 on left hand side of the equation since, on right hand side it is in multiply with the variable when shifted to left hand side it changes to divide

Finally the equation will change having "b" as a subject

b=(a-8)/5

Answer 2

Rearranging the formula and making b the subject of formula is equal to $b = \frac{a - 8}{5}$.

Given the following expression:

• a = 5b + 8

In this exercise, you're required to rearrange the given mathematical (algebraic) expression and make b the subject of formula.

Rearranging the formula, we have;

$5b = a - 8$

Next, we would divide both sides of the formula by 5;

$b = \frac{a - 8}{5}$

Therefore, rearranging the formula and making b the subject of formula is equal to $b = \frac{a - 8}{5}$.
