Answer:
7/15
Step-by-step explanation:
P(appetizers with cheese) = number with cheese / total = 1/5
P(entrees with cheese) = number with cheese / total = 1/3
It is the P(a) + P(b) - P(a and b)
We cannot double count the cheese and cheese event)
P( cheese and cheese) = 1/3 * 1/5 = 1/15
1/5 + 1/3 - 1/15
3/15 + 5/15 -1/15
8/15 - 1/15
7/15
Answer:
1=x
Step-by-step explanation:
because in a term f(X) is the original thing but when a number replaces it that means x = that number
Answer:
50000
Step-by-step explanation:
$25000 car pays 1750 in sales taxes
P x CP = ST
P is the percentage, CP is the price of the car, and ST is the Sales Tax
P x 25000 = 1750
P = 1750/25000
P = 0.07 x 100
P = 7%
what’s the purchase price of a new car with 3500$ in sales tax ?
P x CP = ST
7 x CP = 3500
CP = 50000
2/5x-1/3x=5
Use LCM to solve.
2/5x(*15)-1/3x(*15)=5(*15)
6x-5x=75
x=75
Hope this helps :)
