Lee is thinking of two Numbers,the product is 18. the quotient is 2

defon

X, y - the numbers

The product is 18.
$xy=18$

The quotient is 2.
$\frac{x}{y}=2 \ \ \ |\times y \\
x=2y$

Substitute 2y for x in the 1st equation:
$2y \times y=18 \\
2y^2=18 \ \ \ |\div 2 \\
y^2=9 \\
y=\pm \sqrt{9} \\
y=3 \ \lor \ y=-3 \\ \\
x=2y \\
x=2 \times 3 \ \lor \ x=2 \times (-3) \\
x=6 \ \lor \ x=-6 \\ \\
(x,y)=(6,3) \hbox{ or } (x,y)=(-6,-3)$

The numbers are 6 and 3 or -6 and -3.

Solve for m<c. (Enter your answer as a whole mumber)

kupik [55]

2y + 4 + x = 90

2y + 4 + 3y + x = 180

5y + x + 4 = 180

x = 176 - 5y

2y + 4 + (176 - 5y) = 90

-3y + 180 = 90

-3y = -90

y = 30

x = 176 - 5(30)

x = 26 degrees

Hope this helps! :)
