Hey there, 3/4*n=1 is bascially the same as 3/4n=1, multiply both sides by 4/3, 4*3*3/4n=4/3*1, n=4/3. Therefore, n=4/3

Un muchacho compra el mismo numero de lapices que de lapiceros por 90 soles.Cada laliz le cuesta 3 soles y cada lapicero 7 soles. ¿Cuantos lapices y lapiceros ha comprado?

Answers

Answer:

pencils amount = 9   pens amount= 9

Step-by-step explanation:

We start this problem forming two linear equations system.

3*X+7*Y=90

Where X is the amount of pencils and Y is the amount of pens

The second equation is given by the statement, the amount of pencils is equal to the amount of pens, so the second equation is:

X=Y

Merging both equations we have:

3*X+7*X=90

Solving for X we have:

10*X=90

X=9

X=Y=9

What is 1 5/12 + 4 1/6 in its simplest form?

Answers

The answer is 5 7/12, here's why:

First convert the mixed numbers into improper fractions to make it simpler to deal with.

1 5/12 = 17/12
 4 1/6  = 25/6

Now make them equivalent.

17/12 can stay the same,
25/6 can become 50/12

Now it's just 17/12 + 50/12
Just add the numerators!
17/12 + 50/12 = 67/12

All we have to do from here is simplify 67/12.
12 goes into 67 5 times, with a remainder of 7.
5 becomes the whole number, and our fraction is the remainder (7) over 12.

So 67/12 = 5 7/12.
This is as simplified as the answer can get.

Hope this helps!

What is the perimeter of a square that has an area of 3 inches squared

Answers

Answer: p=4a


Step-by-step explanation: EXAMPLE The area of a rectangle is length times width. Since a square's length is equal to its width, a square's area is equal to the length of one side times itself. So, reversed, the square root of the square's area gives the length of one side. In this case, the square root of 36 square centimeters is 6 centimeters. Again, since all four sides of a square are the same, its perimeter is equal to the length of one side times four. For a square with one side equal to 6 centimeters, the perimeter equals 24 centimeters.   hope this helps

Which ratio can be used to form a proportion with the given ratio? 3 to 4 I NEED THE ANSWER ASAP

Answers


As soon as I see the word "Which ...", I know that there's a list of choices that
goes along with this question, but you decided not to share them.  So there's
no way for me to help you choose the correct one.

In order to form a proportion with 3/4, you need another fraction (or ratio) that's
equal to 3/4 .  Look for a fraction whose numerator is 3/4 of its denominator. 

Here are a few examples:

-- 6 / 8
-- 24 / 32
-- 300 / 400
-- 12 million / 16 million
-- 3x / 4x
-- 15abc / 20abc
-- 3(x+y+z) / 4(x+y+z)
