Zinaida [17]3 years ago

5 0

Answer:

His error occurred in the last step

Explanation:

He was supposed to calculate -

$\frac{5}{6} - \frac{1}{9} \\or\\\frac{15}{18} - \frac{2}{18} \\$

which would equal -

$\frac{13}{18} \\not\\\frac{17}{18}$

Because he added instead of subtracted.

Hope this helps!

Which ordered pair tells the location of the smiley face on the coordinate system?

Jet001 [13]

Answer:

(5,2)

Step-by-step explanation:

You have to look to the X axis and you'll see the smiley face 5 bars/lines across from the vertex or 0.

Next, you'll need to look at the Y axis and see that the smiley face is 2 bars/lines vertically from 0.

So all you need to do is put the numbers into (x,y) and you'll get (5,2)

Hope this helps!
