what is the value of y in the following system of equations? explain how you found your answer

Answers

Answer 1

Step-by-step explanation:

I've used elimination method over here but it can also be done by using substitution.

Answer 2

2x + 3y = 6
2x + y = -2

Solve the second equation for y and substitute into the first equation

2x + y = -2
y = -2x - 2

2x + 3y = 6
2x + 3(-2x - 2) = 6
2x - 6x - 6 = 6
-4x - 6 = 6
-4x = 12
x = -3

Plug back in to solve for y
2x + y = -2
2(-3) + y = -2
-6 + y = -2
y = 4

Plug into other equation to check
2x + 3y = 6
2(-3) + 3(4) = 6
-6 + 12 = 6
6 = 6 :)

Answers

Answer: 160.82

Step-by-step explanation:

First, let’s get the area of the base. To do that, we multiply 9 times 5, which gets us 45. Next, for the two sides of the triangular prism, take 7 times 5, which is 35, and multiply that by two, getting 70. Next, for the two triangles, we have to use the triangle surface area formula, which is 1/2•base•height. So, take the base and the heigh, 9, and 6, and you get 54. Since there are two triangles, we don’t have to divide it by 2. So, we add all of our sides, 54, 70, and 45, and we get 169 sq cm.

You deposit $500 in a savings account that earns 2.5% interest compounded yearly what is the balance in the account after 20 years

Answers

Answer:

the balance in the account after 20 years is $819

Step-by-step explanation:

The computation of the balance in the account after 20 years is shown below:

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= $500 × (1 + 2.5%)^20

= $500 × 1.025^20

= $819

Hence, the balance in the account after 20 years is $819

Jeremy is 12 4 5 years old. Carl is 1 1 6 years younger than Jeremy and Jane is 1 1 3 years younger than Carl. How old is Jane?

Answers

Answer: Jane is 10 9/30 years old

Step-by-step explanation:

Given that Jeremy is 12 4 /5 years old

Carl is 1 1/6 years younger than Jeremy which is why we would subtract giving us

=12 4/5 - 1 1/6

= 11 (24- 5)/30

= 11 19/30 years

and Jane is 1 1 3 years younger than Carl which is why we would subtract giving us

=11 19/30 - 1 1/3

= 10 ( 19 - 10)/ 30

=10 9/30 years

Subtract (-3f - 4g + 9) - (2 - 6f + 5g).

Answers

Answer:

Step-by-step explanation:

Remove the brackets. Watch out for that minus sign. It affects all three terms in the right bracket.

(-3f - 4g + 9) - (2 - 6f + 5g)

-3f - 4g + 9 - 2 + 6f - 5g

+3f - 9g + 7 is your answer.

Answer:

3f−9g+7

Step-by-step explanation:

(−3f−4g+9)−(2−6f+5g)

To find the opposite of 2−6f+5g, find the opposite of each term.

−3f−4g+9−2−(−6f)−5g

The opposite of −6f is 6f.

−3f−4g+9−2+6f−5g

Subtract 2 from 9 to get 7.

−3f−4g+7+6f−5g

Combine −3f and 6f to get 3f.

3f−4g+7−5g

Combine −4g and −5g to get −9g.

- The local museum requires 2 adult
chaperones for every 15 students. How
many adults would be needed with
90 students?

Answers

12. 90/15 is 6. 6x2 is 12.

Answer:

For 90 students, 12 adult chaperones are required.

Step-by-step explanation:

90 (students) divided by 15 gives us a proportion to multiple the amount of adults by.

90/15 = 6

Since there are 6 times as many students as the question provided, we will multiply the amount of adults in the question by 6.

2 x 6 = 12

Other Questions

Suppose you win a small lottery and have the choice of two ways to be paid: You can accept the money in a lump sum or in a series of payments over time. If you pick the lump sum payout, you get $2,950 today. If you pick the payments over time payout, you get three payments: $1,000 today, $1,000 one year from today, and $1,000 two years from today. At an interest rate of 8% per year, you would be better off accepting the payout since it has the greater present value. At an interest rate of 10% per year, you would be better off accepting the payout since it has the greater present value. Years after you win the lottery, a friend in another country calls to ask your advice. By wild coincidence, she has just won another lottery with the same payout schemes.
