70+ 5x < 30+15x I know that x =5 But can someone help me with a real world problem ?

1 answer:

7 0

Remember, you can do anything to an equation as long as you do it to both sides
but, for inequalities, if you multiply or divide both sides by a negative, you flip the sign

70+5x<30+15x
minus 5x both sides
70<30+10x
minus 30 both sides
40<10x
divide both sides by 10
4<x

x>4 is the solution set

a real world problem could be

company A charges a flat rate of $70 dollars to rent their car and also charge a rate of $5 per mile driven

company B charges a flat rate of $30 dollars to rent the car and also charge $15 per mile

how many miles do you have to drive for you to pay more for company B than A?

Answer:

200

Step-by-step explanation:

If the waiters surveyed 50 customers and half of the customer's favorite meat was chicken, then if 400 pieces of meat were ordered 200 pieces should be chicken.

If $\frac{50}{chicken}$ = $\frac{50}{25}$ = $\frac{1}{2}$ , then $\frac{400}{chicken}$ = $\frac{400}{2}$ = $2$
