Rushmore mountain Roosevelt :
nose to head : x/60
2/9=x/60
120=9x
x=120/9= 13 1/3 or 13.33
x=13 foot rounded to the nearest foot
x=6
if you multiply 4 by whats inside the parenthesis you get 5x+16x+44=170
next combine like terms and get 21x+44=170
next subtract 44 from itself and 170 to get 21×=126
finally divide 21 from both sides and you get x=6
hope this helps!
