You can rent a car via two options. Option A charges $20 per day plus $0.10 per mile. Option B charges $0 per day, but $0.50 per mile. How many miles must you drive in one day for option A to be cheaper?

Answers

A minimum of 51 miles must be driven in one day for option A to be cheaper than b.

under option (A) a fixed charge of $20 is to be paid plus $0.10 per mile.

whereas under option (B) only variable charges are to be paid at $.50 per mile.

how many miles should one drive so that cost under both situations is equal?

let's assume miles driven in a day is x

$20+ $0.1 x = $0.5 x

x = 50

if 50 miles are driven in a day cost under both situations is equal and more than that cost under option A will be less, therefore, the miles to be driven in a day should be greater than equal to 51 miles

Elisa filled a bucket with 64 ounces of water. she dumped 5.17 ounces of water .she drank 11 4/5 ounces of water how much water is left in the bucket???

Answers

Answer:

The amount of water left in the bucket is 47.03 ounces.

Step-by-step explanation:

It is given in the question that:-

Total amount of bucket water = 64 ounces

Amount of water dumped = 5.17 ounces

Amount of water she drank = 11 (4/5) ounces

We can write the mixed fraction 11(4/5) as 11.8 ounces

We have to find the amount of water left in the bucket.

Water left = Total amount of bucket water - Amount of water dumped by her - Amount water she drank

By using simple subtraction, we get

Water left = 64 - 5.17 - 11.8 = 47.03 ounces.

64-5.17-11.8=47.03oz

You have used the Distributive Property to transform numerical expressions such as (5)(3) + (2)(3) to (5 + 2)(3). How would you transform 5x + 2x into a single term? Substitute five different values into the expressions 5x + 2x and 7x - 1. What do you notice about the values of the expressions? Is there any value that would make the two expressions equal? Why or why not? No Response(s) Be the first to respond to the Discussion topic!

This is 100 pts

Answers

Answer:

see below

Step-by-step explanation:

we take out a common term (factor) from the expressions /numbers which are being added . In the given expression 5x + 2x , the common factor is x , so we can write it as x(5+2) .

Now we can add 5 and 2 inside the brackets that would be 7 , so in single term it would be 7(x) = 7x .

Substituting 5 different values

In 5x + 2x

1. put x = 0 , 5*0 +2*0 = 0 + 0 = 0

2. put x = 1 , 5*1+2*1 =5+2 = 7

3. put x = 2 , 5*2+2*2 = 10+4 = 14

4. put x =3 , 5*3+ 2*3 = 15+6 = 21

5. put x=4 , 5*4+2*4 = 20+8 = 28

In 7x -1

1. put x = 0 , 7*0 -1 = -1

2. put x = 1 , 7*1-1 = 6

3. put x = 2 , 7*2 -1 = 13

4. put x =3 , 7*3-1 = 20

5. put x=4 , 7*4 -1 = 27

For any value that makes them equal ,

equate the given equations ,

5x + 2x = 7x -1

7x = 7x -1

7x -7x = -1

0 = -1

thus we arrived at a contradiction, so there won't be any values for which the equations will be equal. Also we notice that for same values the result of 2nd equation is one less than equation 1.

And we are done!

Answer: y = -5.5x +18

Step-by-step explanation: -11/2 = 5.5

Answer: y= -11/2x + 7

Step-by-step explanation:

(2,7) and (4,-4)

Do [tex]\frac{y^{2} - y^1}{x^2-x^1} \\[/tex] so it should look like this [tex]\frac{-4-7}{4-2} =\frac{-\\11}{2}[/tex]

[tex]\frac{-11}{2}[/tex] is your slope

Then you need to find your "b" term.

[tex]-4=\frac{-11}{2} (2) +b[/tex]

Multiply -11/2 by 2 and add 11 to both sides

Then do -4 + 11 which equals 7

So 7 is your b term

So your answer is y= -11/2 + 7

Answers

The answer is a because when you’re dealing with positive Powers you do the one on the left first and when you do the one on the left you divide the second number by two and the second number 8 so now it is four. The one on the right you double the second number by two and the second number was four so now it is eight and when the number outside of the parentheses is negative you don’t do anything with it so that is why your answer is a. (And also five and four you keep the same because when even one of them has a negative in them you keep the two main numbers the same which are five and four.)

The heart = 10 and the blue shape = 6

Explanation

First take 16 and we know that one purple tear drop is 3

So 3x2 = 6 - 16= 10 so we now know that the blue triangle must be 6 because 6+10 = 16

Green: 10 (looking at the purple's answer, which is 3.) 16-3-3= 10
Blue: 16
It is shown that they both 'weight' or are the same amount. So, it should be 16. The sun of 10(green) + 6 (the 2 purple)

2(purple) + (green) = blue
2*3 + 10 = 16
6 + 10 = 16
