$y=kx \\ \\
y=144 \hbox{ when } x=12 \\
\Downarrow \\
144=k \times 12 \\
k=12 \\ \\
y=12x \hbox{ and }
x=17 \\
\Downarrow \\
y=12 \times 17 \\
y=204 \\ \\
\boxed{y=204} \hbox{ when } x=17$

Finger [1]

Answer:

347,168 rounded to the nearest ten thousands would be 350,000.

Step-by-step explanation:

When rounding to the nearest ten thousands, you rely on the thousands place value to indicate whether to round up or down. 5 or higher give it a shove, 4 or less let it rest. 7 is in the thousands place meaning we round up. 4 is in the ten thousands place meaning it becomes 5. 347,168 rounded to the nearest ten thousands would be 350,000.
