Answer:

5

Step-by-step explanation:

You can first create an equation to represent the description.  

M = 8h + 10

M is the total money made, and h is the hours spent.  Going to a house costs $10.  This is why it's alone; no matter how many hours is spent at the house, there will always be a $10 charge  Every hour spent at that house costs $8.  This is why it has a variable with it.  This value depends on the time spent.

Plug in the given value ($50) into M and solve for h.

M = 8h + 10

50 = 8h + 10

40 = 8h

h = 5

Five hours were spent at the house.

Answer: You spent 5 hours babysitting.

Step-by-step explanation:

This situation can be represented by the  equation  y = 8x+ 10  where y is the money you earn and x is the  number of hours.

So if  y is equation to fifty dollars then what is x ?

50 = 8x +10    subtract 10 from both sides.

-10           -10

40 = 8x

x = 5

Ugo [173]

Answer:

According to the passage, whales weight 300,000 pounds on average. Narwhales weigh 2,000 pounds on average.

Step-by-step explanation:

Since the question is extremely vague, I'll just answer what's the weight of whales and the weight of narwhals.

According to the paragraph, blue whales weigh 3×10^{5} pounds.

This is what we call scientific notation. You could solve it normally, or you could use a faster method.

Scientific notation states that the first number that you see, the three, is the first part of the answer. The exponent on the number of zero's that there is.

That means that the answer to 3×10^{5} you get 300,000.

Let's do the same thing to Narwhales.

2×10^{3} is 2,000.

The correct answer would be 1.25 inspections an hour because you just need to divide 10 by 8 and you should get 1.25. Hope this helps.
