<u>Answer:</u>
$142500
<u>Step-by-step explanation:</u>
We are given that the resident of a certain University receives a salary that is three times the salary of one of the department heads.
Assuming 
to be the salary of the department head, if the total of the two salaries is $190000, we are to find the salary of the president of the University.
We can write an equation in terms of :
Salary of the president of the University = 
= $142500
Answer:
Step-by-step explanation:
Look at both terms separately, and isolate each "part."
i.e. 12x^4y^2 becomes 12, x^4, y^2
So the problem becomes:
12, x^4, y^2 and
30, x^3, y^1
Then, find the GCF of each term,
30 and 12 - 6
x^4 and x^3 - x^3
y^2 and y^1 - y^1
Hope it helps :) and let me know if you want me to elaborate.
Answer:
$4.53
Step-by-step explanation:
Let us represent
The cost of a
Packet of tea = x
Packet of coffee = y
Five packets of tea and seven of coffee cost $39.40
5x + 7y = 39.40.....Equation 1
Three packets of tea and five of coffee cost $26.20.
3x + 5y = 26.20.......Equation 2
Combining both Equations
5x + 7y = 39.40.....Equation 1
3x + 5y = 26.20.......Equation 2
Multiply Equation 1 by 5 and Equation 2 by 7 to eliminate y
25x + 35y = 197.... Equation 3
21x + 35y = 183.4......Equation 4
Subtract Equation 4 from 3
3x = 13.6
x = 13.6/3
x = $4.53
Therefore, the cost of a packet of tea is $4.53
