Answer:
54 mph
Step-by-step explanation:
If the number of ice cream sandwiches is x
And the number of cookies is y
Then
1.75x + 0.75y = 12.25
and
x + y = 11
y = 11 - x
1.75x + 0.75 (11 - x) = 12.25
1.75x + 8.25 - 0.75x = 12.25
x + 8.25 = 12.25
x = 12.25 - 8.25
x = 4
if x = 4
4 + y = 11
y = 11 - 4
y = 7
x = 4, y = 7
Answer:
y = 8x
Step-by-step explanation:
A proportional relationship has the form
y = kx ← k is the constant of proportion
The only equation in this form is
y = 8x
