I think it's 2.7, yes that's the answer
Answer:
A: -5, -1, 5, 6, 7
B: -12.4, -12.1, -2, 1/2, 12, 12 1/4, 12 1/2
Answer:
112 adults
Step-by-step explanation:
2x+504=11x
11x-2x=504
9x=504
x=56
The ratio is 2:11 so we multiply 56 by 2 and 11. The 2 represents the Adults and the 11 represents the students.
56*2=112 adults
56*11 = 616 students
Just to double check if you do 616-112 it is exactly 504, Therefore the amount of adults is 112.
Have a great day!
Bring like terms together
(REMEMBER CHANGE THE SIGN WHEN MOVING ACROSS THE EQUAL SIGN i.e. - becomes + and + becomes -)
4x - 2x = 7 - 3
2x = 4
divide both sides by 2
x = 2
