Anumber is divided by 3 and then 5 is subtracted from the quotient the result is 1. whats the number?

ANSWER

The number is 18.

EXPLANATION

Let the number be x.

When this number is divided by 3, we obtain the quotient,

When 5 is subtracted from this quotient, we get,

If the result is 1, then we have;

We group similar terms to get,

This gives us,

Multiply both sides by 3.

Therefore the number is 18.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
