Answer:
x-20%
Step-by-step explanation:
I dont know the options, but hopefully this helps
We know that Step 1 is correct, because it is just a restatement of the equation. Therefore, we can eliminate Step 1:
2(5y – 2) = 12 + 6y
In Step 2, the student tried using the Distributive Property. The Distributive Property can be written as one of the two following formulas:
a(b + c) = ab + ac
a(b – c) = ab – ac
In this case, we'll use the second formula. Substitute any known values into the equation above and simplify:
2(5y – 2) = 2(5y) – 2(2)
2(5y – 2) = 10y – 4
In Step 2, the student calculated 2(5y – 2) to equal 7y – 4. However, we have just proven that 2(5y – 2) is equal to 10y – 4.
The student first made an error in Step 2, and the correct step is:
Step 2: 10y – 4 = 12 + 6y
I hope this helps!
It is saying that 80/100 which is .80, so 50*80%= 40
There is two answers D and B
Answer:
Your friend sees you moving at 0.25 m/s upstream.
Step-by-step explanation:
Remember that relative velocity is the velocity of an object in relation to another object. In this example, your friend sees you moving with respect to the river with a relative velocity (Vr) of:
Vr = Yor Velocity (Vy) - The river Velocity (Vriver) =
Vr = 1.25 m/s - 1 m/s = 0.25 m/s
I hope my answer helped you.
