Answer:
the second one seems right but i could be wrong
Step-by-step explanation:
Answer:
The equations whose solutions are -1/2 are:
1. 4x + 1 = 6x + 2
2. 3x + 7 = 5x + 8
Step-by-step explanation:
Using the digits 0 to 9 at most one time each, the equations whose solutions are -1/2 are:
1. 4x + 1 = 6x + 2
-2x = 1
x = -1/2
2. 3x + 7 = 5x + 8
-2x = 1
x = -1/2
The correct answer is letter D
Just believe me thats the correct answer
Hmmm... Maybe divide all the numbers by four and if u get an event number, then that will be your answer!!!
Answer:
Step-by-step explanation:
Hi Millie.
First we can realize that the number of cubes of each type does not matter, only the ratios between them. We see that if there are x yellow cubes, there are 3x blue cubes. And therefore, there are 5*3x green cubes, or 15x green cubes. This means that the cubes are in a 1:3:15 ratio, or that for every 1 yellow cube, there are 3 blue and 15 green cubes.
Now we can find the probability of picking a yellow cube. Since there are 18 non-yellow cubes for every yellow cube, this means that there is a 1/19 possibility of picking a yellow cube.
