Thuy planned for a square table to have a side length of 30 in. but found that it could be a little bigger at 39 in. She found the change of scale below.

StartFraction 39 inches divided by 3 over 30 inches divided by 3 EndFraction = StartFraction 13 over 10 EndFraction. The change of scale is 13 to 10.

What is Thuy’s error

the first one, all those points on the line just make a strait line.

where did you get them? if you picked from the grass, is is probably poisonous.

step-by-step explanation:

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.

8 < i think

hope this !
