Question

Evaluate each expression. (Lesson 1 - 2)

$3+16÷8.5$

Short answer

The value of this expression is 13.

Step-by-step solution

Step 1. Use the order of operations.

The order of operations is the sequence of steps with which we solve any given algebraic expression, order is as follows:

Step 1: Evaluate the expressions inside grouping symbols.

Step 2: Evaluate all powers.

Step 3: Multiply and/or divide in order from left to right.

Step 4: Add and/or subtract in order from left to right.

Step 2. Solve the expression.

We are given that the expression $3+16÷8\cdot 5$

Since expression has both multiplication and division, we proceed from left to right.

First, we perform division as shown:

$\begin{array}{l}3+16÷8\cdot 5\\ 3+2\cdot 5\end{array}$

Next, we perform, multiplication:

$3+10$

Lastly, we perform addition

$\begin{array}{l}3+10\\ =13\end{array}$

Thus the answer is 13.
