Answer:
16
Step-by-step explanation:
Lets assume x is Elgas' age
And y is Alvins age
we know that alvin is 11 years younger than Elga which means,
x=y+11
and the sum of their age is 43
x+y=43
solve it and you get 16
Answer: sorry its not big enough to see sorry
Step-by-step explanation:
An aritmetic sequence is like this

where a1=first term and d=common difference
geometric is

where a1=first term and r=common ratio
can it be both aritmetic and geometric
hmm, that means that the starting terms should be the same
therfor we need to solve

what values of d and r make all natural numbers of n true?
are there values that make all natural numbers for n true?
when n=1, then d(1-1)=0 and r^(1-1)=1, so already they are not equal
the answer is no, a sequence cannot be both aritmetic and geometric
Amount of chocolate milk Ana drinks =
liter
Total amount of chocolate milk in refrigerator =
liter
We have to determine the total number of glasses she will pour
liter of milk from
liter of milk.
Total number of glasses will be determined by dividing the total amount of milk by the amount of milk required for one glass
Total number of glasses = 
= 
= 
= 5.6 glasses
So, 5.6 glasses will be poured from the given amount of chocolate milk.
