Answer:
The sum is
Step-by-step explanation:
Assuming we are finding the sum of :
3e + 7 - e and 2e + 10 + 2e -3
Then we set up the addition as follows:
We group similar try to get:
We now combine the similar terms to obtain:
Therefore the sum is
It's not an irrational number because the decimal is repeating. If it went on forever and never repeated then it would be an irrational number.

Answer:
10 ways
Step-by-step explanation:
Here, we want to calculate the number of ways in which the selection can be made
We have this as follows;
Since we have style starting line up already, it means a choice of 5 has been made from the 13 already. What is left is to make a selection of 3 from 5
To do this, we simply apply the combination formula
that would be;
5 C 3 = 10 ways
5b + r = 30
the cost per item * the number of items sold = the profit
-6 - 3(5y + 4)
= - 6 - 15y -12
= -15y - 18
Hope it helped!
