You need to ensure the denominators are the same. To do this you multiply the denominators together.

1/90 + 2/90

However, this is incorrect, as you need to do the same to the numerators, so for the left hand side you multiplied by 9 and for the right hand side you multiplied by 10, so you must do the same for the numerators.

So it should be:

9/90 + 20/90

You can now add this together, to get:

29/90

This is triple checked so I’m not sure why it says reduce the answer fully as that is as far as it can be reduced.

At Joe's Clown Car Rental Agency, renting a car costs $45 plus $0.75 for every mile it is driven. What is an equation that can b
klasskru [66]

Answer:

y=0.75m+45

Step-by-step explanation:

when you bought the car it was 45, that doesnt change so its a constant

but every mile you drive, it changes, therefore it becomes the dependent or the rate :)

so we just make it into an equation of

y=0.75m+45

where y= the total amount of money owed

and if you wanted to solve for how far the car drove, plug in the 222.5 in for y, as that was the amount owed and solve!

222.5=0.75m+45

177.5=.75m

now divide by .75

m= 236 2/3 miles

hope this helped :))
