Answer:
Step-by-step explanation:
Yes. because In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers
Answer: It is 2.
Step-by-step explanation:
Make both equation equal to each other and solve for x, as following:
- Add like terms.
- Factor the equation.
Substitute the value of x obtained into any of the original equations to obtain the y-coordinate.
Then, this is:
change the mixed numbers into improper fractions
4 1/2 = (2*4 +1)/2= 9/2
1 1/2 = (2*1+1)/2 = 3/2
9/2 divided by 3/2
9/2 * 2/3 = 18/6 =3
She can schedule 3 lessons per night
Calder would have to work 10 hours to equal the same amount Mika has from 9 hours of work
Here's how:
Since Mika works 9 hours and she gets 25 per 3 hours, to get her amount for 9 hours, you times 25 by 3 which is 75
Now you need to set up a equation
To make it easier. you can divide 15 by 2, which is 7.5, to get a unit rate
After that you can set up your equation
7.5x=75
x=10
Hope this helps:)
