Answer:

Step-by-step explanation:
[1] x = 10
[2] 3x + 5y = 20
0? + x = 10 5? + 3x = 20
Answer:
4
Step-by-step explanation:
360 deg = 20
1 deg = 20/360
72 deg = 20/360 * 72 = 4
You must equal zero, so that way 2x can equal 2x
Answer: The correct option is (B) f(q) = 2q + 3.
Step-by-step explanation: The given equation representing a function is

We are to write the equation in function notation with 'q' as independent variable.
From equation (i), we have

So, 's' can be represented as a function of 'q'. Hence, we can write

Therefore, we have

Thus, (B) is the correct option.
20\2=10
10\2=5
5\2=2.5
2.5\2=1.25
