Answer:
5 m
Step-by-step explanation:
48 ÷ 8 = 6
This means the scale factor to get from triangle TSR to triangle PSQ is 6, so...
30 ÷ TR = 6
TR = 5
well, 1/7th of the cupcakes is 3. so 2/7ths makes 6. and 21 minus 6 is 15. So, your answer is 15.
Since there are two minus signs, this equation becomes "5+6" which equals 11.
I believe it would be 3 but dont take my word
