check out the document I have uploaded, and the things I have done in blue; that's how you should show the inequality x>5/2

I have colored the right side because x is greater than 5/2, so instead of coloring the left side because if I color the left side it means that x is less but mow you get the inequality as x greater so you should color the side which increases

the left side means that it decreases

(I wanted to help you with the drawing since you already go help with solving and finding the inequality) Have a great day and I hope this helps

Solve the inequality for x. show each step of the solution -12x-0.4>0.2(36.5x+80)-55

Darina [25.2K]

Let's solve your inequality step-by-step.

−12x−0.4>0.2(36.5x+80)−55

Step 1: Simplify both sides of the inequality.

−12x−0.4>7.3x−39

Step 2: Subtract 7.3x from both sides.

−12x−0.4−7.3x>7.3x−39−7.3x

−19.3x−0.4>−39

Step 3: Add 0.4 to both sides.

−19.3x−0.4+0.4>−39+0.4

−19.3x>−38.6

Step 4: Divide both sides by -19.3.

−19.3x

−19.3

−38.6

−19.3

The sum of two numbers is 21. The larger number is 6 less than twice the smaller number. Find the two numbers.

Vesnalui [34]

Hey there! :D

21= 2x-6+x

21=3x-6

27=3x

x=9

The smaller number is 9.

The larger number is:

9*2= 18 18-6= 12

The larger number is 12.

I hope this helps!
