Do 9 and 10. Thank you!

9. 254.83

10. 1/12

Step-by-step explanation:

9. You can add all three values together to get how much he started with:

14.35 + 148.43 + 92.05 = 254.83

10. You can make this easier by making sure these fractions have the same denominator (bottom number):

7/12 - (2/4 (x3))

7/12 - 6/12 = 1/12

These are your answers

Hope this helps!

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
