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.
Answer:
Reggies makes sence
Step-by-step explanation:
A. (1,4)
EXPALINATION :
IF WE WRITE THE VALUE x = -1 AND y = 4
THEN, y= -8x - 4
4= -8×-1-4
4= 8-4
AND SECOND EQUATION IS : y = x+5
y = -1 +5
y = 4
hence, solved and explained
