Evaluate the expression for the given value of the variable.b+6+4 when b=2.5

Evaluate The Expression For The Given Value Of The Variableb64 When B25 class=

Sagot :

We are given the following expression to solve

[tex]b+6\div4[/tex]

Since the value of the variable b is given, the expression then becomes

[tex]2.5+6\div4[/tex]

Now the question here is what should we do first? addition or division?

Recall the rule of precedence, which says that you should always start with

PEMDAS = Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction

Since division has higher precedence than addition, we will start with division

First, solve the division part 6÷4

[tex]2.5+\frac{6}{4}=2.5+\frac{3}{2}[/tex]

Then, solve the addition part

[tex]2.5+\frac{3}{2}=4[/tex]

Therefore, the answer of the expression (b+6+4) is found to be 4.
