Answer:
6x - 15y = -63
15x -15y = -90
Step-by-step explanation:
We need to multiply the two equations by a constant that will eliminate the y terms.
The two equations are:
2x - 5y = -21
3x - 3y = -18
Let us multiply the first by 3 and the second by 6. The resulting equations will be:
6x - 15y = -63
15x -15y = -90
Note: To solve the system of equations we can simply subtract the first from the second.
Answer:
i think correct answer is a
Factors of 50: 1, 2, 5, 10, 25, 50
Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, ...
The numbers common are: 5, 10, 25, 50
The numbers that are not common are: 1, 2
42.66 / 22 = 1.939, So if you are estimating than anything that is 5 or over is estimated to the top, and anything 4 or less is estimated to the bottom. So in this case 1.939 is estimated to 1.94
