Answer:
Equation: y=.50x+5.00
Answer 1: You would have to pay 15.00 dollars total.
Answer 2: 40 miles
Step-by-step explanation:
Answer 1:
The flat fee is 5.00 dollars. plus it's 00.50 cents per mile. So, what's the half of 20? It's 10. So, 10.00 dollars plus 5.00 is $15.00 .
Answer 2:
Okay, so here, you have $25.00. So, you can go ahead and take the 5.00 away cause that's the flat fee. So, we know that you need $10.00 for 20 miles, so if we have $20.00, then that would take you 40 miles.
24 hours in a day* 14 days in two weeks= 336 hours total
Final answer: 336 hours
Answer:
x = 10
Step-by-step explanation:
2x/3 + 1 = 7x/15 + 3
<em><u>(times everything in the equation by 3 to get rid of the first fraction)</u></em>
2x + 3 = 21x/15 + 9
<em><u>(times everything in the equation by 15 to get rid of the second fraction)</u></em>
30x+ 45 = 21x + 135
<em><u>(subtract 21x from 30x; subtract 45 from 135)</u></em>
9x = 90
<em><u>(divide 90 by 9)</u></em>
x = 10
<h2>
Another solution:</h2>
2x/3 + 1 = 7x/15 + 3
<u><em>(find the LCM of 3 and 15 = 15)</em></u>
<u><em>(multiply everything in the equation by 15, then simplify)</em></u>
10x + 15 = 7x + 45
<u><em>(subtract 7x from 10x; subtract 15 from 45)</em></u>
3x = 30
<em><u>(divide 30 by 3)</u></em>
x = 10

Answer:
165
Step-by-step explanation:
formula is
nCr = n!/(r!(n−r)!)
r= 8 = number of choosing objects from the set
n = 11 = total number of objects in the set
C(n,r)=C(11,8)
=11!/(8!(11−8)!)
! means factorial
factorial means to multiply by decreasing positive numbers.
For example, 8! = 8 ∗ 7 ∗ 6 ∗ 5 ∗ 4 ∗ 3 ∗ 2 ∗ 1 = 40320
=11!/8!×3!
= 165
