Answer:
C=60/h
Step-by-step explanation:
Cost is inversely Proportional to the number of friends who decides to host.
If five (5) friends host the party,
And each friend pays $12 for food and supplies
The equation that describes the relationship is
C=k ×1/h
Where,
C= cost that each host pays
K=constant
h=number of host
Therefore,
$12=k×1/5
$12=k/5
Make k the subject of the formula
$12=k*1/5
Multiply both sides by 5
12×5=k*1/5×5
60=k*5/5
60=k*1
60=k
Sub the value of k into
C=k ×1/h
C=60*1/h
C=60/h
Answer:
2.25 cups
Step-by-step explanation:
There are 5 eights in 40.
1.25 × 5 = 6.25
1.5 × 5 = 7.5
1 × 5 = 5
1 quart = 4 cups
6.25 cups - 4 cups = 2.25 cups
Answer:
The inverse function is 1/5x
Step-by-step explanation:
f(x) = 5x
We want to find the inverse
y = 5x
Exchange x and y
x = 5y
Solve for y
Divide by 5
1/5x = y
The inverse function is 1/5x
Answer:
$2.60
Step-by-step explanation:
Simply divide the amount of money paid for the gas by the number of gallons of gas in the tank. So 38.48 
14.8, which equals $2.60.
