Answer:
x = 7
Step-by-step explanation:
8x = 56
To solve this, we must simplify. To do this, we must divide each side by 8. This, in term, will give us the value of x.
8x = 56
---- ----
8 8
56/8 = 7
x = 7
Our answer is x = 7
You will have to find what x is to get your answer solve each to find the answer
To find probability, you'd have to find the total number of marbles (5+3+6+6=20), and since there are 3 blue marbles, the probability of picking one is 3 out of 20, or 3/20
If that blue marble isn't replaced, there will then be 19 marbles, and 2 blue ones. So the probability of him picking another blue marble is 2/19
N=0 is the answer for this problem
Answer:
x=3/5
Step-by-step explanation:
x^2+4x=5
x+4x=5x
5x+2=5
-2 -2
5x=3
divide 5 from each side
5/5x=3/5
<u>x=3/5</u>
