Answer:
sorry im just answering this cuz need points
Step-by-step explanation:
To solve this, we would be finding the unit rate. To find a unit rate, you should divide the unit by itself, and in this case, the price by the unit. Therefore, our math problem is:
10/10=6.55/10.
1=0.655
We need to round this up as you can not have a fraction of a cent.
0.655=0.66
Using the math above, we can see that 1 pound of potatoes costs $0.66.
Answer:
Quadratic function (assuming 4x2 is 4x^2)
Step-by-step explanation:
Linear functions are ax+b=y
Quadratic is ax^2+b=y
Cubic is ax^3+b=y
Answer:
20 mph
Step-by-step explanation:
time = distance / speed
speed up stream = s - 4
speed down stream = s + 4
time up = time down
8 / (s - 4) = 12 / (s + 4)
cross multiply
8s + 32 = 12s - 48
subtract 8v from both sides
32 = 4s - 48
add 48 to both sides
80 = 4s
Divide both sides by 4
20 = s
20mph
