<u><em>4821216 is rational</em></u>. the definition of rational is a number that ends. this number ends in the ones place which means it is rational
Let the three numbers be x, y and z respectively, then
x + y + z = 62 . . . (1)
y = x - 4 . . . (2)
z = 4x . . . (3)
The above three expressions could be used to represent the numbers.
Solving the three equations, putting (2) and (3) into (1) gives
x + x - 4 + 4x = 62
6x - 4 = 62
6x = 62 + 4 = 66
x = 66/6 = 11
x = 11.
y = 11 - 4 = 7
z = 4(11) = 44
x = 11, y = 7, z = 44.
Answer:
y=4-1/3x
Step-by-step explanation:
1/3x+y=4
y=4-1/3x
Step-by-step explanation:
Center: (−7,4)(-7,4)
Radius: 7
$132.55-($15*12)=$132.55-$180=$-47.45
So then he would have owed 47.45 dollars!
