Answer:
4.3
Step-by-step explanation:
mean=sum of the terms/number of term
room A=3+20+25+0+0+0=25
Room B= 2+18+4+0+0+0=24
room C= 28
room D= 21
room E= 32
step(2)

The area of a regular polygon is equal to
where
P is the perimeter of the regular polygon
a is the apothem
Find the perimeter P
----> the regular pentagon has five equal sides

Answer:
25/28 (Decimal: 0.892857 )
Branliest?
X + 3y = 7
x = -3y + 7
2x + 4y = 8
2(-3y + 7) + 4y = 8
-6y + 14 + 4y = 8
-2y = 8 - 14
-2y = - 6
y = -6/-2
y = 3
x + 3y = 7
x + 3(3) = 7
x + 9 = 7
x = 7 - 9
x = -2
solution is (-2,3)
