Each truck weighs five tons.
1st truck: n
2nd truck: n + 2
3rd truck: n + 4
4th truck: n + 6
n + n + 2 + n + 4 + n + 6 = 32
4n + 12 = 32
- 12 - 12
--------------------
4n = 20
---- ------
4 4
n = 5
X = 69o
2x + 42 = 180
=> x = 69
Answer:
108 rooms
Step-by-step explanation:
Robin can clean 72 rooms in 666 days
means in 666 days rooms that can be clean is 72 rooms
in 1 days rooms that can be clean is 72/666 rooms
in 999 days rooms can be clean is 999\times 72\div 666
after solving we get 108 answer
7)X=20
8)X=14
9)X=45.83 repeating
10)X=-19
11)X=100
12)X=-25
