Answer:
6 4/7
Step-by-step explanation:
I personally break it down like this:
Is 2 greater than 7? No so that means the whole number would stay 5.
Same for the other number. Then add the whole numbers attached to the fraction. Which is 6. Then go to the fraction. 2/7 + 2/7 is 4/7. This cannot be simplified anyfurther.
B) x=2 and y=14 i’m pretty sure lol
A rotation around the origin of 180° and an enlargement by a scale factor of 3
So,
If the number in the ten-thousandth's place is greater than or equal to 5, then round up. If not, round down.
0.1325: Note the 5. We round up.
0.1325 --> 0.133
