The r variable outside the parentheses can multiply both the numbers in the parentheses.
This called distributing the r. We are using the distributive property.
The distributive property states that a(b + c) = ab + ac.
r(18 - 3) = 18r - 3r
So, (r * 18) - (r * 3) is the answer.
Answer:
The answers are: 1 and 1.
Step-by-step explanation:
I believe they are how combinations are written. In other words:
(Ignore the fraction bar, I can't really format it properly).
Anyways, simply find the combination of each:


Note that 0! equals 1.
Answer:
x = 5
Step-by-step explanation:
Since the triangles have to be congruent (through SSS), we know that:
2x + 3 = 4x - 7
We simplify this to: 2x = 10
And then: x = 5
By looking at the table, we can see that the y values are equal to the x values multiplied by 3.
3x = 3*3 = 9
3x =3*9 = 27
3x=3*13=39
3x= 3*20= 60
So, it is a direct variation and the function is y=3x
It would equal 52 fluid ounces
