Suppose the three odd integers are #n#, #n+2# and #n+4#
Their sum is:
#n + (n+2) + (n+4) = 3n+6#
#13# more than twice the largest of the three is:
#2(n+4)+13 = 2n+21#
From what we are told these two are equal:
#3n+6 = 2n+21#
Subtract #2n+6# from both sides to get:
#n = 15#
So the three integers are:
#15, 17, 19#
The answer is 56, multiply 84 by .7 you get 56.
Hope that helped!
Well 15x2=30 and 45 cookies will serve 15 student and you nee to serve 30 students. So you need to multiply 45x2 because 15x2=30.

2
90
so 90 cokkies are needed to serve 30 students.
Answer:
Aries originally had 48 cookies
Step-by-step explanation:
2 is half of 4
4 is 1/4th of 16
16 is 1/3rd of 48
check work by reversing steps:
Aries had 48 cookies, she gave 1/3 (16) to Ana. Ana gave 1/4th (4) to Edna, and Edna gives 1/2 (2) to Ruth.
Ruth has 2, so the work is correct.
