Answer:
Hey there!
1 4/9x+y=2
13x+9y=18
Let me know if this helps :)
Its D
Because the rate of change is 1.5 and 1.5x10 is 15
To see what are the factors use, we write each of the numbers, as product of prime factors:

As we can see, the 4 factors used to produce the numbers in the list are {2, 3, 5, 7}
Answer: {2, 3, 5, 7}
Let call it x
x/4=4/2
->x=8
Answer:x = 1
Step-by-step explanation:
3x + x/4 = x + 3/4
Subtract x from each side
2x + x/4 = 3/4
Times each side by 4
The 4 beneath the x cancels out
3/4 x 4 = 3
2x + x = 3
3x = 3
Divide each side by 3
x = 1
