Answer:
The price of hot dog is $2.5 and that of a pretzel is $1.25.
Step-by-step explanation:
Let the cost of hotdogs be x and that of pretzels be x.
So,
4x+3y = 13.75 ...(1)
and
2x+5y = 11.25 ...(2)
Multiply equation (2) by 2.
4x+10y = 22.5 ...(3)
Subtract equation (1) from (3).
4x+10y-(4x+3y) = 22.5-13.75
4x+10y-4x-3y = 8.75
7y = 8.75
y = 1.25
Put the value of y in equation (1).
4x+3(1.25) = 13.75
4x+3.75 = 13.75
4x = 13.75-3.75
4x = 10
x = 2.5
So, the price of hot dog is $2.5 and that of a pretzel is $1.25.
It should be a positive 5 not a negative so the error was made at the end because u divide

Reflection
Step-by-step explanation:
A reflection is a mirrored image of a shape. Notice how DEC seems to be a "flipped" version of ABC, hence a mirrored image.

Answer:
sqrt(11)
Step-by-step explanation:
3^3+sqrt2^2=11
In a regular polygon, all of the sides have the same length.
Pentagons have five sides. If one of the sides in a regular pentagon is 4 feet, then the rest will also be four feet. 5 sides that are all 4 feet long totals up to a 20-foot perimeter.
