Answer:

8 one-dollar bills

3 five-dollar bills

2 ten-dollar bills

Step-by-step explanation:

Let x = # of one-dollar bills, y = # of five-dollar bills, and z = # of ten-dollar bills. Total amount in the wallet is $43, so the first equation would be 1x + 5y + 10z = 43. Next, there are 4 times as many one-dollar bills as ten-dollar bills, so x = 4z. There are 13 bills in total, so x + y + z = 13

x + 5y + 10z = 43

x = 4z

x + y + z = 13

x + 5y + 10z = 43

x + 0y - 4z = 0

x + y + z = 13

5y + 14z = 43

-y - 5z = -13

5y + 14z = 43

-5y - 25z = -65

-11z = -22

z = 2

x = 4z

x = 4*2 = 8

x + y + z = 13

8 + y + 2 = 13

10 + y = 13

y = 3

A flower bed contains 52 roses and 48 tulips. Two flowers have wilted, what is the probability that the flower is a tulip.
Sergio [31]
First, I add 52 to 48 to get the total amount of flowers.  52 + 48 = 100.  Out of those 100, there are 48 tulips.  If one flower wilted, the probability of it being a tulip would be 48/100, or 0.48.  If a second flower wilted (with only 99 flowers left, and only 47 tulips left), the probability of it being a tulip is 47/99 or 0.474747...  To get the probability of both of those being tulips, multiply the two together.  48/100 * 47/99 = 2256/9900 (then, simplify to 376/1650)

I hope this helps! Can I have Brainliest? :)

How to solve 7 2/6 + 8 5/6
natima [27]
Separate them first.
7+8=15
5/6+2/6=7/6
There can't be 7/6, so it becomes 1 and 1/6,
15+1+1/6=16 1/6
The answer is 16 1/6.
