Answer: 21/100
Step-by-step explanation:
Number of green marbles = 21
Number of blue marbles = 35
Number of red marbles = 18
Number of yellow marbles = 26
Total number of marbles = 100
The probability of choosing a free marble will be:
= Number of green marbles / Tot number of marbles
= 21 / 100
Answer:
I don't know what you are saying for solve for x though if your saying simplify
simplify answer: -9
If 2(3x-6) = 3 (2x-1) answer: No solution
If 2(3x-6) = -3 (2x-1) answer: x = 1.25
Step-by-step explanation:
Answer:
a(n) = 20*2.5^(n - 1)
Step-by-step explanation:
Note that 50 is 2.5 times 20, and that 125 is 2.5 times 50. Thus the common factor is 2.5. The formula for the nth term is
a(n) = a(1)*r^(n - 1) => a(n) = 20*2.5^(n - 1)
Answer:
add them all otherwise I don't know im on that question sorry
Step-by-step explanation:
60 = 40% * x ;
60 = ( 40 / 100 ) * x ;
60 = 2x / 5 ;
2x = 300 ;
x = 300 / 2 ;
x = 150 is full marks.
