Answer:
a= 18 girls in the class, b= 20 boys and 15 girls, 12 oranges better price.
Step-by-step explanation:
for question a, there are 18 girls in the class, this is how i worked it out:
the ratio of boys to girls is 4:3.
there are 24 boys.
24 is 6 times more than 4.
if boys are 6 times more than the original ratio, we also have to times the amount of girls by 6.
6x3= 18.
for question b i got 20 boys and 15 girls, this is how i did it.
there are 35 students in total.
4:3= boys to girls.
4+3=7
7 goes into 35 five times.
ratio of boys to girls is 4:3 so 5x4 for boys = 20 and 3x5 for girls = 15.
answer= 20 boys and 15 girls.
12 oranges is a better deal, this is how i worked it out.
it is 60 for 12 oranges.
it is 48 for 8 oranges.
12x5= 60 , 8x6=48.
you only have to times 12 by 5 to get it to the price but you have to times 8 by 6 to get it to the price, proving that 12 oranges for 60 is a better deal.

Answer:
The relation is 1 digit is being added after every number in the pattern.
So, the 7th term can be found like this.
9+4=13 -4th
13+5=18 -5th
18+6=24 -6th
24+7=31 -7th
Answer:
Step-by-step explanation:
3x^3(1/9x^2-6+2x)
This question is not clear, we can not different between the numerator or denominator of some variable.
3x^3×1/9x^2-3x^3×-6+3x^3×2x
1/3x^(3+2)-18x^3+6x^(3+1)
1/3x^5-18x^3+6x^4
I first begin by dividing 13 by 6 to get 2.16666666667. I then multiple that number by 432 in^2 to get the answer : 936 in^2 for the larger solid.
