Lawrence has a total of 15 five dollar bills and ten dollar bills in his pocket. the value of these bills is $100.00. how many five dollar bills are in lawrence's
pocket?

There are 10 five dollars bills in Lawrence's  pocket.

Step-by-step explanation:

Given,

Total bills = 15,

Let x be the number of five dollar bills,

⇒ The number of ten dollars bill = 15 - x

Thus, the total amount = 5x + 10(15-x)

According to the question,

5x + 10(15-x) = 100

⇒ 5x + 150 - 10x = 100

⇒ - 5x + 150 = 100

⇒ -5x = 100 - 150

⇒ -5x = -50

⇒ x = 10

Hence, there are 10 five dollars bills in Lawrence's  pocket.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
