Answer:
7839716
Step-by-step explanation:
People in building ---- x (men, women and children)
children --- y
men + women + children = x
(3/7)x + (5/8)(4/7)x + y = x
3x/7 + 5x/14 + y = x
times 14
6x + 5x + 14y = 14x
14y = 3x
y + 220 =x
sub into the other one
14y = 3(y+220)
11y = 660
y = 60
then 14(60) = 3x ---> x = 280
So we have 280 people in the building.
check: 3/7 of 280 are men = 120
leaving 160 women and children
5/8 of these ot 100 are women
so we have 120 men, 100 women and 60 children!
hope this is right! have a great. day
Step-by-step explanation:
∛9 × ∛-24
∛-216
∛(-6)³
-6
√(8y⁵) √(40y²)
√(320y⁷)
√(64y⁶ × 5y)
8y³√(5y)
So you know 50% means half right? So then do 32*2 and you get 64.
