Mathematics

I would start by dividing by all the multipliers of the parentheses.
\frac{PV}{nt} = r_{1} +r_{2}
Then, I would subtract the unwanted variable from the sum.
\frac{PV}{nt} -r_{2} = r_{1}

PLEASE HELLLLLLLPPPPPP!!!!!
MariettaO [177]

Answer:

A.

Step-by-step explanation:

First, let's define the types of numbers.

Real numbers: a value that represents a quantity along a continuous line

ex: 1, 5, -6, 0.125, 45.5258,

Integer: Zero, any positive or negative number

ex: -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5....

Whole numbers: a number without fractions [not negative]

ex: 0, 1, 2, 3, 4, 5.....

Rational numbers: any number that can be expressed as the quotient or fraction

ex: 1, 2, 3, 4, 5

Irrational numbers: any number that can't be expressed at the quotient or fraction

ex: pi, [3.14.... (never ending decimal)]  square root of 2....

Based on this information, the false statment would be A. I believe, because

pi is a real number and it is an irrational number.

I hope this helps!!! :)

REAAAALLLLY NEED HELP

If you think about it, the question is asking us to find the greatest common factor, or GCF, of the two numbers, 24 and 18. 
First, find all of the factors of 24. 
The factors are: 1, 2, 3, 4, 6, 8, 12, 24 
Next, find the factors of 18.
The factors are: 1, 2, 3, 6, 9, 18 
List out all of the factors that both of the numbers have. 
The factors are: 1, 2, 3, 6
Whichever is the greatest of these numbers is the GCF. 
The GCF is 6, so the greatest number of groups he can make and still be able to win is 6. 
Hope this helps!
