Answer:
Hotdog: $1.50
Hamburger: $3.25
Step-by-step explanation:
<em>You write down the 2 equations based off of the information as I did:</em>
Let x = cost of a hotdog
Let y = cost of a hamburger
<em>and so:</em>
<em />
3x + 2y = 11
2x + 4y = 16
<em />
<em>Now, we need to find x and y:</em>
<em>We will make both equations equal to y to compare them to each other.</em>
2y = 11 - 3x
y = 5.5 - 1.5x
4y = 16 - 2x
y = 4 - 0.5x
4 - 0.5x = 5.5 - 1.5x
x = $1.5
<em>Now plugging in x into the equation:</em>
2(1.5) + 4y = 16
3 + 4y = 16
4y = 13
y = $3.25
And so hotdog = $1.5 and hamburger = $3.25

Rolling an 11:
n(A): 6&5, 5&6
n(A) = 2
Rolling a 5:
n(B): 1&4, 4&1, 3&2, 2&3
n(B) = 4
n(A) + n(B) = 4 + 2 = 6
400 miles -----------4 hours
X miles ------------2 hours
4x=400.2
4x=800
X=200
Or
400miles --------------- 4hours
X miles --------------- 6 hours
4x=400.6
4x=2.400
X= 600
Answer: 55 Square inches
Step-by-step explanation:
You should find the area of the square and rectangle separately
To find the area you multiply length times width, so the area of the square is 4×4 which equals 16
Then you do the same to the rectangle, 13×3=39
To find the area of the whole figure you add the area of the two shapes together 16+39 which should give you 55
