Answer:
D
Step-by-step explanation:
D is not a function because x's repeat. Each x value should have its own unique y value. The graph also fails the vertical line test, meaning that if you were to draw a vertical line anywhere on the graph it would intersect with more than one point.
The answer is 52.5 because you are suppose to multiply each number in pairs. First multiply 21/61 times 5/8.Then you will get 105/488. Multiply 105/488 times 244/1 which equals 25,620/488. Simplify to the lowest form which equals 6,405/122. Divide 6,405 divided by 122. The answer will be 52.5. That is how you will get the answer.
1/6 +3/6 = 4/6 but if you simply its 2/3
This is quite simple, take 24 and divide it by four to get 6 now all you do is multiply 6 by 7 to get 42 so there are 42 blue marbles.
Answer:
C
Step-by-step explanation:
2x+3x Have the same variable. Therefore they both have like terms
