Answer:
<u>-3+6x</u>
x+3
Step-by-step explanation:
22 ( total) - 10 ( what she has already) = 12 ( the amount she needs to buy)

Than 12 multiplied by $1 = $12
So she needs to spend $12 in order to have 22 hair bands
Answer:
or 80.25%
Step-by-step explanation:
Number of blue Marbles = 4
Number of Red Marbles = 5
Total Number of marbles =4+5=9
In the experiment, two marbles are chosen one after the other with replacement.
The possible outcomes are: BB, BR, RB and RR
The probability of getting at least 1 red
=P(BR or RB or RR)
=P(BR)+P(RB)+P(RR)
Expressed as a percentage, we have:
The probability of getting at least 1 red is 80.25%.
Answer:
2744 pennies.
Step-by-step explanation:
Let x represent the number of pennies Al have initially.
We have been given that Al agreed to give 3/7 of his pennies to Bev, so number of pennies Bev will get would be .
We are also told that Bev gave 3/7 of what she got from Al to Carl, so number of pennies that Carl will get would be .
Further, Carl gave 3/7 of what he got from Bev to Dani, so number of pennies that Dani will get would be .
We are also told that Dani received 216 pennies. Now, we will equate 216 to and solve for x as shown below:
Therefore, Al have 2744 pennies initially.
