How Do I Do This Math Problem?

Answers

Answer 1

Answer:

13/9

Step-by-step explanation

d=2-5/9

d=13/9

Answer 2
First you are going to multiply each side by 9 to get rid of the fraction.

you should now have d+5 = 18

then you subtract 5 from both sides and now your answer is:

d = 13

Rapid Rental Car charges a $40 rental fee, $25 for gas, and $0.65 per mile driven. For the same car, Capital
Cars charges $55 for rental and gas and $0.75 per mile.
Part 1 out of 2
For how many miles is the rental cost at both companies the same?
The rental costs at both companies are the same at
miles.

Answers

Equation

40 + 15 + 0.25x = 45 + 0.35y

Solution

55 + 0.25x = 45 + 0.35y The only way you can do this is to assume that x and y are equal

subtract 45 from both sides

55 - 45 + 0.25x = 0.35x

10 + 0.25x = 0.35x Subtract 0.25x from both sides.

10 = 0.35x - 0.25x

10 = 0.1x Divide by 0.1

10/0.1 = x

x = 100 So if each car goes 100 miles, it should turn out to be the same no matter which company gets the rental.

Let's see if that is true.

Cost for the first company = 40 + 15 + 0.25x = 55 + 25 = 80 dollars.

Cost for the second company = 45 + 0.35x = 45 + 35 = 80 dollars.

Conclusion

Both rentals charge the same total amount when each car is driven 100 miles.

The charge is 80 dollars.

Hope this helped! :)

3x+2y=5

Hop this helps

Answer:

3x > 2y

Step-by-step explanation:

I'm not sure if this answer is correct, so I'm sorry if you get it wrong. There are 3 x blocks, so you that's how you get 3x. There are 2 y blocks, so that's how you get 2y. The y blocks look smaller/less than the x ones, so I said that 3x is greater than 2y.

Answer:

how to graph x<-28 on a number line

Answers

Draw out a number line. Make sure -28 is on the number line, along with other optional values (such as 0 perhaps). At -28, plot an open circle or hole. This indicates this value is not part of the solution set. This is because there is no "or equal to" as part of the inequality sign. Then shade to the left to indicate values smaller than -28.

So in summary, you'll have an open hole at -28 and shading to the left.

Answers

Answer:

a) 60% finished the race    b) 40% did not

Step-by-step explanation:

if this is useful please make me brainliest

60 fin 40 didnot

**Explanation:** Most of the time, people use percentages to express a fraction or a portion of a whole. In fact, percent literally means "per 100" or "out of 100." So when you see 25 percent, for example, you could read it as "25 out of 100" or "25 per 100 parts." But you can also have percentages that are greater than 100 percent – and when that happens, there's at least one complete whole, or a whole number, hidden in there somewhere.
