Answer:
B
Step-by-step explanation:
A is not a function because the same x value is repeated twice with different y values. The same goes for C and D so the answer is C.
Here are two ways of solving this problem.
Method A. Using fractions.
You will need 3 times as much milk, so you need to multiply 3 by 2 3/4.
First, convert 2 3/4 into an improper fraction.
2 3/4 = 2 + 3/4 = 2/1 + 3/4 = 8/4 + 3/4 = 11/4
Now multiply 11/4 by 3.
3 * 11/4 = 3/1 * 11/4 = 33/4
Now convert 33/4 into a mixed numeral.
33/4 = 8 1/4
Answer: 8 1/4
Method B. Using decimals.
You will need 3 times as much milk, so you need to multiply 3 by 2 3/4.
First, convert 2 3/4 into a decimal number.
2 3/4 = 2.75
Now multiply 2.75 by 3.
3 * 2.75 = 8.25
Now convert 8.25 into a mixed numeral.
8.25 = 8 + 0.25 = 8 + 1/4 = 8 1/4
Answer: 8 1/4
Answer:
D D D
Step-by-step explanation:
The second one or y = 7.50x
That is because the four pounds of almonds divided by thirty dollars is 7.50. So if you were to add one more pound of almonds, you would have to pay $7.50 more.
Because is the ratio of two natural numbers
8.8=88/10=44/5
