Answer:
x = 53/6 , y = -55/6
Step-by-step explanation:
Let the 2 numbers be x and y.
x+y = -1/3 ........... (1)
x-y = 18...............(2)
This is a simultaneous equation we will use elimination method.
Add equation 1 and 2
2x = 18 - ⅓
2x = 17⅔
2x = 53/3
Multiply both sides by 3
6x = 53
Divide both sides by 6
x = 53/6
Put x = 53/6 into equation 1
x+y = -⅓
53/6 + y = - ⅓
y = -⅓ - 53/6
y = -55/6
Therefore x = 53/6 , y = -55/6

Answer:
Yes, the distance and time is a proportional relationship. The constant of proportionality is 65. X*65 = y.
Step-by-step explanation:
Full box=180 calories
C(x)=number of calories
x=number of mints
therefor
full box=180=(10/3)x
180=(10/3)x
solve for x aka number of mints per box
multiply both sides by 3/10 ( since 10/3 times 3/10=30/30=1 so 1x)
540/10=x
54=x
54 mints per box
Answer:
32
Step-by-step explanation:
