The expression in the form 9n

We know that Company B will be less expensive at first, but Company A will become a better option as the miles rack up. Eventually, Company A will be less expensive. There will be a point where the price will be the same for each company.  

150 + .20x = Company A

70 + .40x = Company B

If we set these two equations equal to each other, we find out when the price will be the same.

150 + .20x = 70 + .40x

If we solve for x, we find out how many miles must be driven in a day to make the rental cost the same. After that, Company A will be a better deal.

At 350 miles, the rental costs for company A and company B become the same. This result is found by setting the two cost functions equal to each other and solving for the number of miles.

To find when the rental costs from both companies are the same, you need to set the expenses equal to each other and solve for miles (m). The cost for company A can be represented as 130 + 0.30m (130 dollars for the daily rental and 0.30 dollars per mile) and the cost for company B is represented as 60 + 0.50m (60 dollars for the daily rental and 0.50 dollars per mile).

Upon setting the costs equal to each other: 130 + 0.30m = 60 + 0.50m, and simplifying, you'll get 0.20m = 70. Therefore, by dividing by 0.20, m = 350.

So, at 350 miles, the rental costs for both companies A and B are the same, with each charging the same amount for the truck rental.

Remark

Start with the product

Let the unknown number = x

The unknown number x is multiplied by 6

At this point you get 6x

====================================

Now you add 15

6x + 15 = 9

Solve

6x + 15 = 9      Subtract 15 from both sides.

6x = 9 - 15       Collect the terms on the right.

6x = - 6            Divide by 6

x = - 6/ 6

x = - 1

You must find the unit cost in dollars per gallon for each purchase by dividing the cost by the number of gallons.

Graven: $55.20 for 15 gallons

$55.20/(15 gal) = $3.68/gal

Project: $72.80 for 20 gallons

$72.80/(20 gal) = $3.64/gal

Answer: Project paid less per gallon.

Step-by-step explanation:

Well we won't give you the table, but it's pretty easy. It's a fixed rate so you know he charges the same thing every time. 36 / 3 = 12

So if he mows the lawn and gets paid $12 each time, you can multiply everthing in your x input to get your y output. So for x = 8 your y output would be y = 96 because 12 * 8 = 96

It is 128.1 pounds.....

Answer:

There is 127.91lbs in that many kilograms.

Step-by-step explanation:

In order to find this, you need to know the unit rate. There is 2.2lbs in every kilogram. Therefore, we can multiply the number of kilograms that we have by 2.2 to get the correct answer.

58.14*2.2 = 127.91

The answer is y = 6 which is option B.

Solution for y:

4y + 13 = 37

= 4y = 37 - 13

= 4y = 24

= y = 24/4

= y = 6

The number is 63 which is divided by -7 and the quotient is increased by 12, the result is 3.

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division, thus, can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.

We have been given that when a number is divided by -7 and the quotient is increased by 12 and the result is 3.

Let the number be x;

x ÷ -7

By hit and trial method, if we consider a number which is a multiplier of 7 and 3.

then it would be 63, now apply this number to the given condition.

63÷ -7 =  -9

Also, the quotient is increased by 12, the result is 3.

-9 + 12 = 3

Hence, the number is 63.

Multiply normally, ignoring the decimal points.

Then put the decimal point in the answer - it will have as many decimal places as the two original numbers combined.

So, 16.04 (5.25)=84.21

Answer:

Step one- You first get the decimals -example-( 3.2 x 2.4 )

Step two- You then put the biggest decimal at the top and smallest at the bottom -example-( 3.2

                            x 2.4 )

You can take away the decimal points for now if it helps.

Step three- You multiply the first number, in this case, the first number is 4. Then multiply the 4 by the top numbers ( Only multiply the 4 an the 2 then multiply the 4 and the 3.)

Then you do the same to the 2 at the bottom.

After you finish multiplying that, then you add the numbers leftover.

Finally you count how many numbers are behind the decimal. In this case, there are 2 numbers behind the decimal, so you would put the decimal 2 numbers behind.

You will begin to see how it works.

We have to complete the table.

What is Function?

A relation between a set of inputs having one output each, is called Function.

Now,

Function is given as;

f (x) = x - 5

Hence, after putting all the given values of x, we get;

Put x = -1,

Then, f (x) = -1 - 5 = - 6

Put x = 0

Then, f (x) = 0 - 5 = -5

Put x = 1

Then, f (x) = 1 - 5 = -4

Put x = 2

Then, f (x) = 2 - 5 = -3

Put x = 4

Then, f (x) = 4 - 5 = -1

Therefore, All values of f (x) are;

⇒ -6, -5, -4, -3, -1

Answer: a.) 22.5 lb and b.) 67.5 lb

Step-by-step explanation:

a.Weight of 1/5 square foot sample of wood = 1/2 lb

Multiplying 5 on both sides we get ,

weight of 1 square foot sample of wood=1/2×5=5/2 lb

Now, 1 square yard = 9 square feet

Thus weight of sample of wood in 1 square yard = 9 ×weight of 1 square foot sample of wood=9×5/2=45/2=22.5 lb

b. Weight of three square yards of wood=3 times weight of wood in 1 square yard

=3×22.5=67.5 lb

Each square foot of wood weighs 2.5 lbs, so one square yard (or 9 square feet) weighs 22.5 lbs. Josh would therefore need 67.5 lbs of wood to construct his birdhouses.

This question requires a basic understanding of ratio and proportion. The information given is that Josh's sample of wood, which covers an area of 1/5 square foot, weighs 1/2 lb. However, wood is sold by the hardware store in square yards, and we know that 1 square yard equals 9 square feet.

In other words, each single square foot of wood weighs 2.5 lbs (1/2 lb divided by 1/5). So, the weight of 1 square yard of wood (9 square feet), would be 2.5 lbs per square foot times 9, or 22.5 lbs.

If Josh needs three square yards of wood for his birdhouses, he would therefore need 3 times 22.5 lbs, or 67.5 lbs.

it instantly becomes positive because the negatives are close to each other as shown.

hope that helps :)

Since an integer is any whole (not fractional) number on the number line, all you have to do is move to the left however many units you're subtracting by from the point given. Say the problem is 3 - 7. This means we start at 3, and move to the left 7 units, which lands us at -4. However, if we had a problem like 12 - (- 2), the two negatives would cancel out, meaning we will move to the right 2 units on the number line, or 12 + 2, which is 14. Some other examples are:

-12 - 4, (you should get -16)

3 - 8, ( you should get -5)

16 - (- 3), ( you should get 19)

I hope these tips helped you out! I know that when I first had to subtract integers, using a number line really helped me out. Eventually, it'll just be a natural thing. :D
