Mathematics

likoan [24]3 years ago

4 0

Answer:

(1, 2)

Step-by-step explanation:

Subtract the second equation from the first:

(y) -(y) = (6x -4) -(-x +3)

0 = 7x -7 . . . . . simplify

0 = x - 1 . . . . . . divide by 7

1 = x . . . . . . . . . add 1

y = -1 +3 = 2 . . . substitute into the second equation

The solution is (x, y) = (1, 2).

16, 4,1,...<br> Find the 6th term

Vlada [557]

Let's see what to do...

_________________________________

Step (1)

Look : 16 , 10 , 4 , ...

It is an arithmetic sequence.

So first we have to find the value of the ratio(( d )) .

To do this, we need to subtract each sentence minus the previous sentence.

So we have : 10 - 16 = - 6

_________________________________

Step (2)

To find the nth sentence in an arithmetic sequence, we must use the following equation :

$t(n) = t(1) + (n - 1)d$

_________________________________

Step (3)

To find the 6th term just need to put the following parameters in the above sequence.

t(1) = 16 ------ n = 6 ------ d = -6

$t(6) = 16 + (6 - 1)( - 6)$

$t(6) = 16 + (5)( - 6)$

$t(6) = 16 + ( - 30)$

$t(6) = 16 - 30$

$t(6) = - 14$

_________________________________

And we're done.

Thanks for watching buddy good luck.

Five times the number of test tubes in a school’s chemistry lab exceeds three times the number of beakers it has by 660. The sum

vladimir1956 [14]

5t=3b+660....and....2t+5B=450

from the first we can see that the t=(3b+650)/5 and using this value in the second.

(6+1320)/5+5b=450 making all have common denominator.

6b+1320+25b=2250

31b=930

b=30.. and 2t+5b=450

t=150

Which is the best example of a down payment?

Maru [420]

Answer:

Step-by-step explanation:

Proof by some contradictions:

D is not a good example because she does not pay anything upfront

B is not a good example because he pays <u>everything </u>upfront with some of the money from a third party

A is not right because the 500 is a security deposit, which is a different concept from a down payment

Therefore the answer should be C, where money is payed upfront and payed after he receives the product.
