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: 30/100 = .3
Step-by-step explanation: Division by 100 decimal moves left two spaces
Rates are usually unit rates since unit rates are only for one amount for example: $35/1 video game. Rates are also written like 35 dollars per video game. a problem would ask how much would it be for 6 video games
1. Reverse the numerator and denominator of the second fraction and change the division sign to a multiplication sign
2. Multiply the 2 fractions (By multiplying the numerators and the denominators).
3. Simplify is necessary.
Hope this helped!
Answer:
-4y -12
Step-by-step explanation:
We cannot solve, but we can simplify
3(y-4)-7y
Distribute the 3
3y -12 -7y
Combine like terms
3y-7y -12
-4y -12
