Answer:
Step-by-step explanation:
4 6 x y 10
As x is the median number of this sequence, we know that the mean would be equal to this.
The mean is defined as:
So we can say that:
Rearranging this, we get:
As we know that:
So we can substitute in values and see which fit the equality:
Subbing in x as 6 gives us,
However, y must be bigger than x and must be between 6 and 10, so this is incorrect.
Subbing in x as 7 gives us,
As 8 is bigger than 7, and is in between 6 and 10, this means all of our inequalities have been met and we have the correct answer.
Like terms are terms that have the same variable no matter the coefficient value such as a negative or positive coefficient (number right to left of the variable aka the letter representing an unknown amount of value).
A. 8n : - 4n becuase the have the same variable (N)
B. - 2d: D because they have the same variable and even if d has no coefficient, it still has value, variables with no coefficient always equal 1 no matter the circumstances
C. - b: 17b and -3b2 because they both have the same variable eliminating the coefficients being two different types of numbers (positive and negative). The expressions have to have the same variable.
D: 4y², -3y2,4y, and 4 to the second power. This is because they all have the same variable.
E. 6x2y: 3xy because the variable are specifially xy and they must be in order to be like terms.
abc: all because they have all the letters but are just in different orders of variables. (thats all)
Answer:
Multiply the decimal for the percent of tax by the purchase price, then add the amount of tax to the price to find the total price.
Step-by-step explanation:
Sales tax is an amount added to a price to get the total.
We multiply by the decimal for the percent; this means we divide the percent by 100 before we multiply.
Once we multiply, this gives us the amount of sales tax. We add this to the price of the item to get the total purchase price.

Answer:
A. 3p < 10.2
Step-by-step explanation:
The answer is the above mentioned because by solving 3p < 10.2, you divide both side by the number attached to the variable 'p'. ie 3p/3 < 10.2/3 and that gives you p < 10.2/3. 10.2/ 3 gives you 3.4. ie p<3.4. Therefore making the answer A. 3p<10.2
