Answer:
x is equal to 15.
Step-by-step explanation:
In order to solve this, we need to set it up as a proportion.
6/8 = x/20
Now that we have the proportion, we need to cross multiply to solve.
6*20 = 8*x
120 = 8x
15 = x
Answer:
B
Step-by-step explanation:
Given inequality is open at - 3 and closed at 4. Therefore the required inequality would be:

Thus, option B is the correct answer.
X - y = 8
x + 2 = 3y.....x = 3y - 2
3y - 2 - y = 8
2y = 10
y = 5
x - y = 8
x - 5 = 8
x = 8 + 5
x = 13
so x = 13 and y = 5
