Answer: 20%
Step-by-step explanation:
The probability that a randomly selected marble will be pink can be found by the formula:
= Number of pink marbles / Number of total marbles
= 4 / 20
= 20%
<em>There is a 20% chance that if you pick a marble, it will be pink. </em>
Answer:
y=1x
Step-by-step explanation:
Answer:7
Step-by-step explanation:
8+4=12
2(x-1)= 2x-2
12=2x-2
now add 2 to both sides
14=2x
And divide both sides by 2
7=x
Hmmm......
Then, you must be thinking of 19.
Explanation:
Let you numher be x
now
according to question
multiply it by 8 and it becomes 8×x = 8x
Now add 22
so it becomes
8x + 22
now as told in the question take the same number again i.e x for one more time.
multiply it by 6
and you'll get 6x
and after adding 60 you'll get 6x + 60
Now again according to question
8x+ 22 and 6x+60 are same number therefore they must be equal,
8x+22 = 6x+60
Do a little azebra
8x -6x = 60 -22
2x = 38
x = 19.
and Tada, your number is here.
