Answer:
1/5
Step-by-step explanation:
Both Amir and Tamara ate 2/5 each.
2/5 + 2/5 = 4/5
If 4/5 of the candy bar was eaten, 1/5 of the candy bar remains because
5/5 - 4/5 = 1/5
(Remember that 5/5 just equals one whole, representing the whole candy bar)
Answer:
Infinite pairs of numbers
1 and -1
8 and -8
Step-by-step explanation:
Let x³ and y³ be any two real numbers. If the sum of their cube roots is zero, then the following must be true:
Therefore, any pair of numbers with same absolute value but different signs fit the description, which means that there are infinite pairs of possible numbers.
Examples: 1 and -1; 8 and -8; 27 and -27.
B, x=12 because 140-80=60, 60/5=12
It's 61/21. That's the answer.
