First you have all ten books, but then every time after, you loose one because you can't put the same book in the group twice.
10 * 9 * 8 * 7 = 5040 groups
Yes! This is because -150/10 can be simplified to be -15, which is a rational number.
The word “rational” sounds like another math word you’ve heard of before. Do you know what it is?
Well, it’s “ratio”!! Ratios can be seen in the forms x:y and x/y.
ANY RATIONAL NUMBER HAS THE ABILITY TO BE WRITTEN AS A RATIO!! This will completely exclude numbers with super long decimal points (ex: 1.2345678809928374737272828...)
This number also meets the requirements of being an integer. An integer is any whole number (this excludes decimals and fractions)
I know it’s written as a fraction. However, the fraction could be simplified, making it -15, which means this is both a rational number and an integer!!
Answer:
No
Step-by-step explanation:
To see if (2,2) is a solution, substitute them into the inequality and see if it is true.
2 is our x value, and 2 is also our y value
y < 4x – 6
2< 4(2)– 6
2 < 8 – 6
2 < 2
This statement is false. 2 is not less than 2, so (2,2) is not a solution to this equation.
Answer:
8/9
Step-by-step explanation:
1 blue, 2 yellow, 7 red, 6 green, and 2 purple marbles = 18 marbles
The number that are not yellow = total - yellow
P( not yellow) = number that are not yellow / total
= (18-2) / 18
= 16/18
=8/9
The price difference/ the original price and times the whole equation by 100 (to get the percentage).
> ($50/$150) x 100 = 33% (rounded)
