Answer:
Equation: 125 x 2 = x
250 ribbons
Step-by-step explanation:
We have to find the total number of ribbons used. Since Nell sold 125 packages of cookies and each package has 2 ribbons, we can make the equation 125 x 2 = x. Let x = the number of ribbons used in total. We multiply them to get 250. Therefore, 250 ribbons were used.

Answer:x=13
BMC=75 degrees
Step-by-step explanation:
（x+2）+（5x+10）=90 degrees
so 6x+12=90
x=13
5x+10=5x13+10=75 degrees
The underlying arithmetic progression is
-15, 0, 15, 30, ...
starting with 
and with a common difference of 
between terms. Recursively, this sequence is given by
So we have
and so on, so that the explicit rule for the sequence is
for 
.
The series consists of 15 terms, since
So we have
and the answer would be B.
Um, I think you have to find three pools near you and measure them to answer your question.
