15 = 0.23x
x = 65.2
therefore 15 is 23% of 65.2
C
the shades part 14 x14 = 196
but the there a square that is in the middle one so 8x8 =64 i subtract them and get 132
W=2j, m=5w, (m+4)=6(j+4)
using w from first in second you get:
m=5(2j)=10j, m+4=6j+24
m=10j, m=6j+20, since m=m we can say
10j=6j+20
4j=20
j=5, and since m=10j
m=50
So the man is 50 years old
