Title: Determine the value of an expressions

Grade: 6-b Lesson: S3-L10

Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Steps	Problem	Solution
1	Determine the value of an expression by substituting the value m = 3	\$ 5m - 15/m \$
2	Now substitute "m" value in the expression	\$ 5(3) - 15/(3) \$
3	After multiplication we get	\$ 15 - \cancel15^5/\cancel3^1 \$
4	After cancellation we get	\$ 15 - 5 \$
5	After simplification we get	\$ 10 \$
6	Answer	B = \$ 10 \$

Steps

Problem

Solution

Determine the value of an expression by substituting the value
m = 3

\$ 5m - 15/m \$

Now substitute "m" value in the expression

\$ 5(3) - 15/(3) \$

After multiplication we get

\$ 15 - \cancel15^5/\cancel3^1 \$

After cancellation we get

\$ 15 - 5 \$

After simplification we get

\$ 10 \$

Answer

B = \$ 10 \$
