If you add 5 to me and then divide by 9, you get3. What number am I

Answers

Answer 1

Answer: First we need to reverse all of these operations. So, you need to start with three. It says to divide by nine, so then you multiply three by nine. Three times nine is equivalent to 27.

Now you have the number 26. Reverse the addition to subtracting and you get the final answer 22.

Let's check it. 22 plus five is 27. 27 divided by nine equals three.

So you final answer is three.

What is 4/5 - 3/4?????

Answers

Well first you have to find a common denominator. 5 and four, their least common denominator is 20 so make the denominator 20.

4/5 = 16/20

3/4 = 15/20

16/20 - 15/20 = 1/20

$(4)/(5) - (3)/(4)$

$= (4)/(5) + (-3)/(4)$

$= (16)/(20) + (-15)/(20)$

$= (16+-15)/(20)$

$= (1)/(20)$ is your final answer.

What is a number system?

A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.

The given number is 7.89. The ( 1 / 10 ) of the number will be calculated by forming the equation.

Let the unknown number be x. Form the equation for the number and solve.

x ( 1 / 10 ) = 7.98

x = 7.98 X 10

x = 79.8

Therefore, the number 7.98 is ( 1 / 10 ) of 79.8 number.

3x+y=15 5x-4y=8

resolucion de sistema por el metodo de sustitucion

Answers

Answer:

x=4

y=3

Step-by-step explanation:

we have the following equations

3x+y=15 equation 1

5x-4y=8 equation 2

using equation 1 we have:

y=15-3x equation 3

using equation 3 in equation 2 we have:

5x-4(15-3x)=8

5x-4*15+4*3x =8

5x-60+12x = 8

17x=68

x=68/17

so we have x=4

finally in equation 3:

y = 15-3(4)

y = 15-12

y = 3
