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.
Well the answer is 13 and cannot be written in simplest form because 1/2 and 1/2 have the same denominator so you add them together and you get 2/2 which is a whole number then you add the other whole numbers but don’t forget the new whole number then add the 5 and you get 13 cm
10° is your answer for the angle
Answer:
The length between the two points is RT = 1.3 units
Step-by-step explanation:
The coordinates of the point R and T are R(2,1.2) and T(2,2.5).
Now, by DISTANCE FORMULA:
The distance between two coordinates P and Q with coordinate P(a,b) and Q(c,d) is given as:
So, here the distance RT = 
or, RT = 1.3 units
Hence, the length between the two points is RT = 1.3 units
