Answer:
6
Step-by-step explanation:
The expression can be rearranged to ...
b = 3 -9/(a+5)
In order for b to be an integer, (a+5) must be an integer divisor of 9. There are exactly 6 of those: ±1, ±3, ±9.
The attached table shows the values (a, b) = (x₁, f(x₁)).
Answer:
36.
Step-by-step explanation:
Please correct me if i'm wrong! :)
60 tables total. 25% of those seat 22 people. 60 X 25% = 15. So 15 of the tables seat 22 people.
The remaining tables (60 tables - 15 tables = 45 tables) seat 44 people.
So you have:
(15 tables X 22 seats) + (45 tables X 44 seats) = total seats.
2310 TOTAL seats.
Answer:
Bill got more ($1.62) for each pound exchanged than did Gwyll ($1.56).
Step-by-step explanation:
Let's calculate the unit rate in each case, that is, the number of dollars obtained through exchanging one (1) pound for dollars:
Bill:
$729
--------- = $1.62 per pound
£450
Gwyll:
$780
---------- = $1.56 per pound
£500
Bill got more ($1.62) for each pound exchanged than did Gwyll ($1.56).
