ANSWER IS 5
so
how many years ago=x
so
'in how many years ago (-x) was ethan 5 times older than son
40-x means ethan's age x years ago
12-x means son's age x years ago
so
ethan's age x years ago is 5 times as much as son's age 5 years ago
40-x=5(12-x)
distribute using a(b+c)=ab+ac
40-x=60-5x
add 5x
40+4x=60
subtract 40
4x=20
divide 4
x=5
ANSWER IS 5 years

Use the pythagoras theorem to find the number of blocks between Shakillah's and Reyna's house
= sqrt (12^2+ 5^2) = aqrt 169 = 13 blocks
distanc,e from school to Shaquilla's house = 12 - 0 = 12 blocks
.. .. .. .. .. ... .. Reyna's house = 5 -0 = 5 blocks
So total number of blocks in entire trip = 5 + 12 + 13 = 30
