The difference of two numbers is 42. the larger number is three less than six times the smaller number. find the numbers.

IgorLugansk [536]

X and y are the numbers
x>y

diffference is 42
x-y=42

larger is 3 less than 6 times smaller
x=-3+6y

subsitute -3+6y for x

x-y=42
-3+6y-y=42
-3+5y=42
add3 to both sides
5y=45
divide both sides by 5
y=9

sub back

x=-3+6y
x=-3+6(9)
x=-3+54
x=51

the numbers are 51 and 9

Lisa plays soccer 3 out of the 7 days of the week. How many possible schedules are there to play

jonny [76]

Answer:

There are 25 possible schedules.

Step-by-step explanation:

The order in which they play soccer is not important(Monday and Tuesday is the same as Tuesday and Monday), and thus the combinations formula is used to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Monday but not Tuesday:

Monday(1) and 2 out of the remaining 7 - 2 = 5. So

$C_{5,2} = \frac{5!}{2!3!} = 10$

Tuesday but not Monday:

Tuesday(1) and 2 out of the remaining 7 - 2 = 5. So

$C_{5,2} = \frac{5!}{2!3!} = 10$

Monday and Tuesday:

Monday and Tuesday(1), plus one out of the remaing 5 days. So

$C_{5,1} = \frac{5!}{1!4!} = 5$

Total:

10 + 10 + 5 = 25

There are 25 possible schedules.

Reposting this because I’d prefer more than one answer, please respond with the “Sample Response” if possible!!

Anon25 [30]

Answer:

Sample Response

Step-by-step explanation:

He is incorrect because if you substitute x for 37 you will get the equation 8×37+200. 8×37=296 +200= 496. Since it is not greater or equal to 500 the inequality is not true.
