Answer: 55 Miles
Step-by-step explanation:
75x11=825
11x5=55
The equation you can use is x + 3x = 428 with x as the number of cheeseburgers and 3x the number of hamburgers
you solve for x and get 4x= 428 and x=107
so 321 hamburgers were sold that day.
X^2=3^2+7^2-*3*7cos52
x=6.083
7^2=3^2+6.08^2-2*3*6.08cosy
solving for y
y=94.71
