You just add up all of the sides to find the x
Answer:
5/30
Step-by-step explanation:
put the smaller number first and then the second number
3 pencil 4 bubblegum 2 sports cards
You had to divide each by 3
follow order of operations:
3+16/4 = 3+4 = 7
We will use the segment addition postulate.
PQ + QR = PR
4x - 1 + 3x - 1 = 54
7x - 2 = 54
7x = 56
x = 8
So QR is 3(8) - 1 or 24 - 1 which is 23.
