<u>Answer:</u>
$6.00
<u>Step-by-step explanation:</u>
To solve this problem, we have to construct two separate equations for each family, and then use any of the methods for solving simultaneous equations.
Let's consider <em>h </em>to represent the cost of 1 hot dog, and <em>w </em>to mean the cost of 1 water bottle.
• For the first family:

We can rearrange the equation to make <em>w</em> the subject:
⇒ 
⇒ 
• For the second family:

Since we have previously obtained an expression for <em>w</em> in terms of <em>h</em>, we can substitute that expression for <em>w</em> in the above equation, and then solve for <em>h</em>:
⇒ 
⇒ 
⇒
[Multiplying both sides of the equation by 3]
⇒ 
⇒ 
⇒ 
∴ The price of one hot dog is $6.00.
Answer:
6x = 48
i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
Select any two x and plug it into the equation to get the corresponding y:
I’ll do 1 and 2 for example.
x = 1
y = -2(1) + 4
y = -2 + 4
y = 2
So we have the point (1, 2)
x = 2
y = -2(2) + 4
y = -4 + 4
y = 0
We have the point (0, 2)
Plot (1, 2) and (0, 2) and draw the line that goes through both.
