Step-by-step explanation:
Given







Required
The weighted average
To do this, we simply multiply each score by the corresponding worth.
i.e.

So, we have:

Using a calculator, we have:

--- approximated
$5125.78. For simple questions like this you can search them on google and find answers very quickly so you dont waste points btw.
Answer:
B) 6(x+2y) + 4 = 6x + 12 y + 4
200/5 = 40 miles per inch. 40x7=280 actual miles.
Answer: B) 3+y+3
This can be simplified to y+6, but the current un-simplified expression has 3 terms.
======================================
Explanation:
Terms are separated by a plus sign. If you had something like 10x-5y, then you would write that as 10x+(-5y) showing that 10x and -5y are the two terms.
Choices A and C, xy and 6y respectively, have one term each. They are considered monomials. Mono = one, nomial = name.
Choice D is the product of the constant 3 and the binomial y+3. Binomials have two terms.
Only choice B has three terms, though we can simplify it down to two terms. I have a feeling your teacher doesn't want you to simplify it.
