Answer:
Cards C and E
Step-by-step explanation:
Remember that irrational numbers cannot be written as a fraction of two integers:
Is 10 irrational? No, because 10 can be written as a fraction (ex. 10/1, 20/2, etc.)
Is 6/5 irrational? No, because it is a fraction.
Is π irrational? Yes, because it can't be written as a fraction as its digits continue infinitely without repetition.
Is 11/4 irrational? No, because it is a fraction.
Is 8.25635... irrational? Yes, because the ellipsis shows the digits continue infinitely without repetition, otherwise there would be a bar over the digits to show repetition
Is -7 irrational? No, because it can be written as a fraction (ex. -7/1, -14/2, etc.)
Is 6.31(bar) irrational? No, because the bar shows that the digits 3 and 1 repeat.
Therefore, only cards C and E are irrational.
Answer:
I don't now
Step-by-step explanation:
I am not sure
w - 7 > - 4 To solve the inequality, you need to get the variable (w) by itself, to do so, you add 7 on both sides of the inequality
w - 7 + 7 > -4 + 7
w > 3 [w is a number greater than 3]
(If you are using an open circle and closed circle, otherwise you can skip)
When the sign is < or >, you have an open circle "o"
When the sign is ≤ or ≥ (less/greater than or equal to), you have a closed circle
Make an open circle on the number 3, then make an arrow pointing to the right because w is greater than 3.
If you don't have to do the open/closed circle, just make a dot on the number 3 and make an arrow pointing/going to the right
Answer:
4
Step-by-step explanation:
Another way to write this is 8/1 x 1/2. Then the answer would be 8/2. Simplify to get 4.
