Evaluate. 13⋅[18÷(15−9)] enter your answer in the box.

The value of the expression is 39.

Step-by-step explanation:

Consider the provided expression.

13⋅[18÷(15−9)]

According to PEMDAS rule we first solve parenthesis, exponents, multiplication, division, addition, subtraction.

Now use the above rule and first solve the parenthesis as shown:

13⋅[18÷(6)]

13⋅[18÷6]

Now perform the division inside the parenthesis as shown below:

Perform the multiplication.

Hence, the value of the expression is 39.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
