Problem 13
10p+10q factors to 10(p+q). If we apply the distributive property, we can distribute the 10 to each term inside (p and q) to get
10(p+q) = (10 times p)+(10 times q) = 10*p + 10*q = 10p+10q
so we get the original expression again. Here 10 is the GCF of the two terms.
--------------------------------------------------------------
Plug p = 1 and q = 2 into the factored form
10*(p+q) = 10*(1+2) = 10*(3) = 30
As a check, let's plug those p,q values into the original expression
10*p+10*q = 10*1+10*2 = 10+20 = 30
We get the same output of 30

Answer:
Sample spaces are for example, if I flip a coin and spin a wheel that has 1, 2, and 3 on it, the sample space would be {H1,H2,H3,T1,T2,T3}. So, sample spaces list the possibilities of a given set.
A) x=4
B) x= -3
C) x= -1/6
D) x=24
To determine what percentage of 642 the number 321 is, we can follow the equation below.
(Smaller Number / Bigger Number)*100
We can plug the numbers into the equation to get our answer.
(321/642)*100 = 0.5 *(100) = 50%
So 321 is 50% of 642
