4(-2)-7-d(-2)<10 what is the largest integer value of d

Question

 i want to know what the largest integer value of d is

 

Answer 1

4(-2) - 7 - d(-2) < 10

 

 

This is inequality.  We must solve the inequality to find the solution of d.  Also, an integer is a whole number and not a decimal number.

 

Use distributive property to get rid of parentheses.

 

-8 - 7 + 2d < 10

 

-17 + 2d < 10

 

 

Add 17 on both sides of inequality.

 

2d < 27

 

 

Divide both sides of inequality by 2.

 

d < 27 / 2

 

d < 13.5

 

This means that d is all numbers less than 13.5

 

The largest integer value of d in this range is 13.
