Hello there,
Their combined weight is = 65 kg + 22x kg + 13x kg
                                         = 65 kg + 35x kg
y= (65+35x)kg

Hope this helps:))

What two numbers add to be 6 and multiply to be 15
yarga [219]
   
\displaystyle \bf \\
x_1+x_2=6\\\\
x_1\cdot x_2=15\\\\
\Longrightarrow~~x^2-6x+15=0\\\\
x_{12}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}=\frac{6\pm\sqrt{36-60}}{2}=\\\\
=\frac{6\pm\sqrt{-24}}{2}=\frac{6\pm2\sqrt{-6} }{2}=3\pm i\sqrt{6}\\\\
x_1=\boxed{3-i\sqrt{6}}\\\\
x_2=\boxed{3+i\sqrt{6}}\\\\
\texttt{Verify:}\\\\
x_1+x_2=3-\underline{i\sqrt{6}}+3+\underline{i\sqrt{6}}=3+3=6~~correct\\\\
x_1\cdot x_2=(3-i\sqrt{6})(3+i\sqrt{6})=3^2-(i\sqrt{6})^2=9+6=15~~correct

-x + 4y = -4<br> y = 1/2x -2
anygoal [31]
<h2>(x, y) = (6, 1)</h2>

Step-by-step explanation:

-x + 4y = -4

y = 1/2x -2

-x + 4(1/2x - 2) = -4

-x + 2x - 2 = 4

x = 4 + 2

x = 6

y = 1/2x - 2

y = 1/2 x 6 - 2

y = 3 - 2

y = 1

(x, y) = (6, 1)
