Artemon [7]3 years ago
5 0

Answer:

6, 24, 54 and 600

Step-by-step explanation:

To find the first 3 terms, substitute n = 1, 2, 3 into the formula, that is

6(1)² = 6 × 1 = 6

6(2)² = 6 × 4 = 24

6(3)² = 6 × 9 = 54

The first 3 terms are 6, 24, 54

Substitute n = 10 into the formula for 10th term

6(10)² = 6 × 100 = 600

Paul and Tom both commute to work. Paul's commute on the train takes 15 minutes more than one third as many minutes as Tom's com
Ronch [10]

Answer:

  45 = (one third)x + 15

Step-by-step explanation:

If x represents the number of minutes Tom commutes, then (1/3)x is "one-third as many minutes as Tom's commute." 15 minutes more than that is ...

  (1/3)x + 15

We are told this is the length of Paul's commute, and that it is 45 minutes. So, the appropriate equation is ...

  45 = (1/3)x +15

6v+13b=377<br> 4v+9b=259
aleksandr82 [10.1K]

Answer:

v = 13

b = 23

Step-by-step explanation:

To solve this system of equations, we can negate one equation and add it to other to cancel out one variable.

Looking at v and b, the coefficients are 6, 4 and 13, 9, respectively.

It would be easier to use the LCM of 6 and 4

E_1 : 6v + 13b = 377\\E_2:  4v + 9b = 259\\\\4E_1 + (- 6)E_2:\\24v + 52b = 1508\\-24v - 54b=-1554\\\\0v -2b = -46\\-2b = -46\\b = 23\\\\4v + 9(23) = 259\\4v + 207 = 259\\4v = 52\\v = 13\\\\6(13) + 13(23)\\78 + 299\\377

a machine can reduce 21 inches of ribbon every 3 minutes. How many feet of ribbon can the machine make in one hour?
Zarrin [17]
Okay. Let's make a proportion for this. So we can do 21/3=x/60. Let's multiply cross way. So 21 x 60 is 1260. We multiply 3 by x to get 3x. So our equation will be 3x=1260. We can isolate the equation by 3, and 1260 divided by 3 is 420. So x=420. We then have to convert into feet. So 420 divided by 12 is 35. So it would be 35 feet. Therefore, the machine can make 35feet of ribbon in a hour.
