A because you subtract 15from 20 and it =5 or 1/4
Answer:
Step-by-step explanation:
B) S = {1,2,3,4,5,6}
n(S) = 6
B = factors of 2 when rolling a single die = {1 , 2}
n(B) = 2
P(B} = 
A) n(S) = 50
A = Picking numbers with 3 in tens place = {30, 31,32,33,34,35,36,37,38,39}
n(A) = 10
P(A) = 
Ok well since it says the product of a number and 6 is 44 more than twice the number. and from this they got 6x=44+2x because it SAYS THE PRODUCT OF A NUMBER U DON'T KKNOW WHAT THE NUMBER IS SO U USE A VARIABLE WHICH IS 6X THEY GOT = 44 FROM THE PRODUCT AND 2X FROM MORE THAN TWICE THE NUMBER AND TWICE IS 2 AND U DON'T KNOW WHAT THE NUMBER IS SO ONCE AGAIN USE A VARIABLE
HOPE THIS HELPED
