Answer:
Given m∠RST = (15x - 10)o
Using angle addition postulate:
m∠RST = m∠RSP + m∠PST (15x - 10)= (x + 25)+ (5x + 10)(15x - 10)=
so your answer would be (6x+35)
Step-by-step explanation:
You have to multiply the number of people times the number of cookies they are each supposed to get
So, 28 x 3 = 84 cookies
you divied the 10.30 by 10 and get 1.03
