Divide the amount he has to pay off with the 8 months. That is 200 divided by 8 which is 25. He has to pay 25 each month.
D (56.5)
Originally, the train traveled 340 miles in 8 hours
If we use the formula d/t, we'll have 340/8, which is 42.5
If we add 14, then we'll have 56.5, or d
Answer: Third option.
Step-by-step explanation:
According to the information given in the exercise, you can find an approximation of the the total cost in dollars of raising a child in the United States ( from birth to 17 years) given a household's annual income, with the following equation:
Where "x" represents the household's annual income in dollars.
Therefore, if the annual income is $62,500; you can identify that:
Then, in order to calculat the approximated cost to raise a child in a household with that annual income given in the exercise, you need to substitute that value of "x" into the equation and then you must evaluate in order to find the value of "y".
Through this procedure you get the following result:
First, replace the “?” with an x:
x - 2x - 5 = 5
Next, combine alike terms:
[ x - 2x ] - 5 = 5
^ alike terms
This will result in:
-x - 5 = 5
You do the inverse (opposite) of -5
-x -5 = 5
+5
Once you do the plus 5, the five moves to the end of the equation:
-x - 5 = 5 + 5
+5>>>>>^
The “-5” no longer exists because you canceled it with the “+5” that you moved to the other side.
The new equation:
-x = [5 + 5]
^ you add these two
After adding you get:
-x = 10
When putting “x” into a number it will ALWAYS be 1.
You then divide both sides by the “x” (which is -1 since it it always equal to one but is negative because it has a negative sign on it)
Your new equation:
-x / -1 = 10 / -1
If you divide to negatives, this will result in a positive.
You’re left with:
-x / -1 = x (since two negatives become a positive result)
10 / -1 = 10 (if there’s a negative and positive when dividing, it will automatically become negative) [ONLY FOR DIVISION]
At the end you’re left with:
x = -10
