Answer:
$2.75 = cost of a hot dog
$4.50 = cost of a cheeseburger
Step-by-step explanation:
Let x = cost of a hot dog
y = cost of a cheeseburger
(1) 2x + 4y = 23.5 (2) 5x + y = 18.25
y = 18.25 - 5x
2x +4(18.25 - 5x) = 23.5
2x + 73 - 20x = 23.5
-18x + 73 = 23.5
-18x = -49.5
x = 2.75 y = 18.25 - 5(2.75)
y = 18.25 - 13.75
y = 4.50
$2.75 = cost of a hot dog
$4.50 = cost of a cheeseburger
Answer:
BRO I DONT KNOW SORY I NEED POINTS
Step-by-step explanation:
Answer:
Step-by-step explanation:
Is there more to this?
7/6x=140
since variable x is multiplied by 7/6, find x by multiplying by the inverse of 7/6 which is 6/7.
7/6x × 6/7 = 140 × 6/7
x= 120
Using the Fundamental Counting Theorem, it is found that she can choose 180 different meals.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with 
ways to be done, each thing independent of the other, the number of ways they can be done is:
In this problem:
- For the meat, there are 3 outcomes, hence
.
- For the two vegetables, 2 are taken from a set of 6, hence, applying the combination formula,
.
- For the dessert, there are 4 outcomes, hence
.
Then:
She can choose 180 different meals.
