It's a factor. This concept is widely used throughout algebra, and you'll probably bump into it through the end of high school and beyond.
A common use is expressing a term in <em>prime factorization</em>, or reducing a number to its most base parts- primes. For example:
Of course, a number like 13 which is already prime is made up of itself and 1. <em>Factors do not have to be primes.</em> 20 is also reducible through combinations of 1, 2, 4, 5, 10, and 20. Prime factorization is just a handy example.
Basically, factors multiply with each other to create other numbers, and numbers can be reduced down to their factors.
Answer: x=10 and y=5
Step-by-step explanation: Let be the number of hours worked by the first mechanic.
Let be the number of hours worked by the second mechanic.
They worked for a combined total of hours. So we have the following equation.
The first mechanic charged per hour and worked for hours.
So, the first mechanic charged dollars.
The second mechanic charged per hour and worked for hours.
So, the second mechanic charged dollars.
Together they charged a total of . So we have the following equation.
The two equations above give us a system of linear equations.
We can solve the first equation for .
We then substitute for in the second equation to find .
Answer:
6:9
or 6 to 9
Step-by-step explanation:
Answer and explanation:
A function is given f(x)= y where x is independent variable and y is dependent variable. Y is a function of x therefore y takes up a value because x has a certain value, y is dependent on x values.
Therefore if government office y is a function of minister's name x then a government office would hold a particular value, example be named after the minister's name because it is dependent on the minister's name x
