(1 2/3 − 3/5 )÷3 1/2 + 1/3

help me i beg of you

67/105

Step-by-step explanation:

you find the common denominator

first you do 1 10/15 - 9/15 equals 1 1/15

then you divide it by 3 1/2

then add it to 1/3

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
