Answer:
x = 1/5, y = 6
Step-by-step explanation:
5x + y = 7
y = 7 - 5x
Set equations equal to each other to eliminate y
7 - 5x = 20x + 2
7 = 25x + 2
5 = 25x
x = 1/5
y = 7 - 5(1/5)
y = 7 - 1
y = 6
Answer:
Mr Ronaldo paid $4,932 in income tax
Step-by-step explanation:

Income tax = $4,932
The answer should be false
Answer:
<h2>12</h2>
Step-by-step explanation:
To evaluate 4P2, we will use the permutation formula as shown;
nPr = 
4P2 = 
4P2 = 12
If you would like to solve the equation 7 * x = 42, you can calculate this using the following step:
7 * x = 42 /7
x = 42 / 7
x = 6
The correct result would be A. x = 6.
