0.15x+55>0.10x+80 how do i work this out?
work it just like an equation, remembering to reverse the direction when multiplying/dividing by negative values:
0.15x+55>0.10x+80
0.15x - 0.10x = 80 - 55
0.05x = 25
x = 500
Oops. forgot it was not an equation:
0.15x+55>0.10x+80
0.15x - 0.10x > 80 - 55
0.05x > 25
x > 500
To solve this inequality, you need to isolate the variable x. Here are the steps:
Step 1: Simplify both sides of the inequality by combining like terms.
0.15x + 55 > 0.10x + 80
Step 2: Subtract 0.10x from both sides to eliminate the variable from the right side of the inequality.
0.15x - 0.10x + 55 > 0.10x - 0.10x + 80
0.05x + 55 > 80
Step 3: Subtract 55 from both sides to isolate the 0.05x term.
0.05x + 55 - 55 > 80 - 55
0.05x > 25
Step 4: Lastly, divide both sides of the inequality by 0.05 to solve for x.
(0.05x)/ 0.05 > 25 / 0.05
x > 500
So, the solution to the inequality is x > 500.
