Answer:
This will give 5 Students each in 12 different equally sized groups
This also shows that students can grouped in equal groups of 12 in 5 places
Step-by-step explanation:
From the question we are told that
60 children in equal sized groups
Generally interpreting 
can be mathematically represented as
a)
This will give 5 Students each in 12 different equally sized groups
b)
This also shows that students can grouped in equal groups of 12 in 5 places
18 per adult, 9 per child total equals 2,475,00 and the hold of guest is 150
Answer:
y = 51.32º
Step-by-step explanation:
z = 180 - 47 - 90
z = 43º
sin43 = opp/hyp
sin43 = 35/y
y = 35/sin43
y = 51.32º
Answer:
x = -3.5 or -1
Step-by-step explanation:
Add 7 and factor.
2x^2 +9x +7 = 0
(2x +7)(x +1) = 0
x = -3.5 or x = -1 . . . . . values that make the factors zero

<em>Comment on factoring</em>
Factoring ax^2 +bx +c = 0 requires you find factors of ac that have a sum of b. Here, you're looking for factors of 2·7 = 14 that have a sum of 9. If you're observant, you realize that 2+7=9, so 2 and 7 are the factors you want.
Now, you can write the factored form as ...
(ax +p)(ax +q)/a = 0 . . . . where p and q are the factors of ac we just found
The divisor "a" is used to simplify one or both of the factors. Here, we have ...
(2x +2)(2x +7)/2 = 0
(x +1)(2x +7) = 0 . . . . . . we removed a factor of 2 from the first binomial
