15x is greater than or equal to 525
the answer is X is greater than or equal to 35
If there are 40 children aged twelve and under and x of them are under three years old, 40 - x aged three twelve years old. From the 92 people that where taken by the company on whale watching trips, 52 are over twelve years old. The equation that best show the total cost, C is
(40 - x)(36) + (52)(48) = C
Rearranging the equation gives,
x = 40 - ((C - 2496)/ 36)
P(5,2) = 5!/3! = 20
in 20 ways you can give medals
A=6 because 54/9=6
For b, the picture is not very clear and so I can’t see properly but if it says b/3 then b=45 because 15•3=45
c=11 because 23-12=11
I don’t think there is a number that does both of those, the factors of 49 are 1, 7, and 49
