The answer is 5/72 you would just divide 5/6 by 12 hope this helped
2 rooms would be 62+42 which is 104
3 rooms would be 104+42 which is 146
4 rooms would be 146+42 which is 188
5 rooms would be 188+42 which is 230
6 rooms would be 230+42 which is 272
but these are the prices including the 20$
without the 20$ the prices would be
2 rooms is 84
3 rooms is 126
4 rooms is 168
5 rooms is 210
6 rooms is 252
Answer:
16
Step-by-step explanation:
as an expression: (15 - 6) + (-2 + 9)
simplify quantities: (9) + (7)
sum: 16

<span>let x be number of bicycles
and y the number of</span> tricycles<span>
So
x + y = 25 equation 1
The number of wheels is
2x + 3y = 63 equation 2
</span>We can multiply the equation 1 by two and subtract from the second one...
2x + 3y = 63
-(2x + 2y = 50)
then
y = 13 trikes and
x = 12 bikes
1.2(w+5)=3
1.2w+6=3
-6 -6
----
1.2w = -3/1.2
w= -2.5
