2+1=3
15/3=5
split the 3 5's in ratio 2:1 and you get 10:5

Answer:
Step-by-step explanation:
A regular nonagon has vertices that are 360°/9 = 40° apart. Any rotation by a multiple of 40° will make the figure indistinguishable from the original.
Rotational symmetry of 40° applies.
Rotational symmetry of 200° applies.
Answer:
<em>9-3=6</em>
Step-by-step explanation:
An addition/subtraction fact family has 2 addition equations and 2 subtraction ones.
The question already states both addition ones, but only one subtraction
The subtraction one stated is 9-6=3
The opposite is<em> 9-3=6</em>
