Answer:
Step-by-step explanation:
Hello There!
The shown figure is a parallelogram
If you didn't know the opposite angles of parallelograms are congruent ∠A≅∠C and ∠B≅∠D
so we can set up an equation to solve for w
because ∠B≅∠D we use this equation
14w + 50 = 28w - 45
now we solve for w
step 1 add 45 to each side
-45+45 cancels out
50 + 45 = 95
now we have 14w + 95 = 28w
step 2 subtract each side by 14w
28w-14w=14w
now we have 14w = 95
step 3 divide each side by 14
14w/14=w
we're left with
Answer: choice C
Step-by-step explanation:
The union of events A and B, denoted ∪ , is the collection of all outcomes that are elements of one or the other of the sets A and B, or of both of them. It corresponds to combining descriptions of the two events using the word “or.”
**keep in mind that we don’t write numbers more than once in these sets(choiceB)
so the answer would be
{3,4,5,6,7,8,9}
Answer: price of total notebooks = p(a+b+c) or pa+pb+pc= price of total notebooks
Step-by-step explanation:
you have to add all the number of notebooks or a b and c and then multiply it by the price of each notebook. there are multiple ways to do this but those are the ways I could think of.
if a=2, b=3 and c=6 then you have to add 2+3+6 to equal 11 then multiply 11 by the price of each notebook, say p=$4.50 your equation would be 4.50*11 which is $49.50, and that would be the total of all the notebooks. these numbers metaphorical of course, but hope that puts it into perspective.
