Find the solution to the system. Write your solution as an ordered pair (x,y) with no spaces, no solution, or infinitely many. x=2y-7 and 4x+y=71 *

Answers

Answer:

The solution is (15, 11)  There is only one solution.

Step-by-step explanation:

Solve this system using substritution.  In the second equation replace x with 2y - 7, obtaining:

4(2y - 7) + y = 71, which simplifies as follows:

8y - 28 + y = 71, or

9y = 99.  then y must be 11.  If y is 11, then x = 2y - 7, or x = 2(11) - 7 = 15

The solution is (15, 11)  There is only one solution.

Find the 8th term of the geometric sequence 6, 18, 54, ...

Answers

Answer:

13122

Step-by-step explanation:

6 x 3 = 18; 18 x 3 = 54; continue to do this 8 times and you get 13122!

Answer:

a(8) = 6*3^7 = 13122

Step-by-step explanation:

Each new term is equal to the previous one times the common ratio, r, which in this case is 3.

The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1).

In this particular case, we have a(n) = 6*(3)^(n -1).

The 8th term of this sequence is a(8) = 6(3)^(8 - 1), which works out to:

a(8) = 6*3^7 = 13122

Gabe paid $ 120 for 3 shirts and 2 pairs of pants.

Each shirt cost $15.
Each pair of pants cost the same amount.
The equation 3s + 2p = 120 can be used to determine p, the cost of each pair of pants.

Gabe solved the equation using the following steps:

3s + 30=120

3s= 90

s= 30

Therefore, Gabe calculates the cost for each pair of pants as $30. Did Gabe find the cost for each pair of pants correctly?

If he did, justify each step of Gabe's solution using mathematical properties.
If he did not, describe any error Gabe made in his calculations and determine the price of each pair of pants.

Answers

Answer:

3s+2p= $120

each shirt is $15

3(15)+2p= $120

45+p=120

p= $75

each pair of pants is $75 and each shirt is $15

3s+2p= $120

3(15)+ 2(75)

okay, this is wrong, never mind, im confused-

welp ._.

Step-by-step explanation:

he doesnt add the pants to the equation and he finds the value of the shirts when we already know that value.

Answer:

Row 1

Step-by-step explanation:

If you divide the number of oranges in each row by their number of boxes, you always get 13 oranges per box.

(156/12 = 13)

(130/10 = 13)

(91/7 = 13)

(65/5 = 13)

But, in Row 1, he made a mistake: 13/2 = 6.5 The mistake here is that Row 1's "number of boxes" should be 1, not 2, to make this eqation true. If we did this, then we will get 13 as our "number of oranges" instead of 6.5, becuase the equation will now be 13/1 = 13 and his table will be correct.

Row 1 has the mistake.

Christopher spent a total of 52.50 at a bookstore he purchased a calendar for 9 and three books that cost the same

Answers

Answer:

Cost of each book = 14.5

Step-by-step explanation:

Given:

Total amount spend = 52.50

Cost of calendar = 9

Number of books = 3

Assume;

Cost of each book = a

Find:

Cost of each book

Computation:

Total amount spend  = Cost of calendar + Number of books(Cost of each book)

52.50 = 9 + 3(a)

Cost of each book = 14.5
