Answers

Answer:

W = 8.2 cm

Step-by-step explanation:

The perimeter formula is P = 2W + 2L and here the perimeter is 65.6 cm.

Thus, 65.6 cm = 2W + 2L.  Substituting 3W for L, we get

          65.6 cm = 2W + 2(3W) = 8W.

Solving for W by dividing both sides by 8, we get W = 65.6 cm / 8, or

W = 8.2 cm

W=8.2 cm. Trust me I have my sources.

Answer:

so you would add $129 to $20 then you add p to the $20 because it doesnt say how many pairs he sold so we need to add an exponent. But then you need to put all that into and equation whihc leads you to get the answer of

Answers

Answer:

h + c = 3 and 4h + 4c =10

No solutions

Step-by-step explanation:

If hot dogs = h, and chips = c,

Then the first scenerio can be written as h + c = 3

The second scenerio is 4h + 4c = 10.

So, your system should be

h + c = 3 and 4h + 4c =10

Solve this system

First, solve c + h = 3 for c.

Subtract h on both sides.

c = -h + 3

Then, substitute c = -h + 3 into the second equation (4c + 4h = 10)

4(-h + 3) + 4h = 10

Simplify.

- 4h + 12 + 4h = 10

12 = 10

This is not right, so this system has no solutions. This means that there is no set cost for the chips or hot dogs (or for both).

Hope this helps! Feel free to ask any questions

Ruby says that 4/5 divided by 2/15 = 14/15. What error did Ruby make? A. Ruby added instead of divided. B. Ruby divided 2/15 by 4/5 instead of 4/5 by 2/15. C. Ruby divided by 2 instead of dividing by 2/15. D. Ruby multiplied by 2/15 instead of 15/2 multiplying by .

Answers

Answer:

A. Ruby added instead of divided

Step-by-step explanation:

You must find a common denominator (15), and then multiply by the reciprocal and simplify your final answer

12/15 times 15/2 equals 180/30 which, when simplified equals 6

Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.

What is simplification?

Using mathematical operations it is to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Ruby says that 4/5 divided by 2/15 = 14/15, which is incorrect.
4 / 5 divided by 2/15 is 6,
When we add both numbers,
= 2 / 15 + 4 / 5
= [2 + 12] / 15
= 14 / 15

Thus, Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.
