Step-by-step explanation:
know that
h = 3
h × h × h
3 × 3 × 3

Step-by-step explanation:
3x + 5y = 50
x + 5y = 31
use substitution
x = 31-5y
3(31-5y) +5y = 50
93 -15y + 5y = 50
93 - 10y = 50
--10y = -43
y = 43/10 = $4.30 for kids
now solve for x
x + 5(4.30) = 31
x + 21.5 = 31
x = $9.5 for adults
5.07, the 4 is the thousands
39° because a right angle adds up to 90°
