{y= -1-3x
{y + 3x = 3

Answer:

x=15

Step-by-step explanation:

Like solving all Algebra equations, it is very important to make sure that the variables (In this case x) are on one side and the numbers are on the other side.

85-3x=40

First, let's subtract 40 on both sides

45-3x=0

Add 3x to both sides

45=3x

Let's divide both side by 3

And we get...

x=15

Answer: Ok while i was working out this problem I started by multiplying so i started by 5

2.50 x 5 = 12.5

3.25 x 5 = 16.25 then I added then and got 28.75. So i was like i should go higher. I picked 7.

2.50 x 7 = 17.5

3.25 x 7 = 22. 75 then I added those two and got 40.25 when i got that I was like yes, Im getting closer. So i picked 9 then I got..

2.50 x 9 = 22.5

3.25 x 9 = 29.25 and that equaled 51.75

so then i was like oh! Taxes so I think the answer might be 8. 46 plus tax lol.

Answer:

she invested 6600 at 3% and 3400 at 2.5%

Step-by-step explanation:

Simple interest = amount deposited x time x interest rate

Let the amount deposited in in the account bearing 3% interest by represented with a

Let the amount deposited in in the account bearing 2.5% interest by represented with (10,000 - a)

a x 0.03 + (10,000 - a) x 0.025 = 283

0.03a + 250 - 0,025a = 283

collect like terms

0.03a - 0.025a = 283 - 250

0.005a = 33

a = 6600

the amount deposited in the 2.5% account = 1000 - 6600 = 3400

Answer: 238.8

Step-by-step explanation:

To get an average, you add the weights together, the sum. And then you divide by how many children there was.

To go backwards, you'd times the average by the amount of children there were, 3, to get the sum

79.6 times 3 is 238.8

Answer:

[tex]6\pi[/tex], 6pi

Step-by-step explanation:

The area of the full circle would be [tex]\pi *4^{2}[/tex], which is [tex]16\pi[/tex]

A full circle is 360 degrees. Since we are only taking a part of that, 135, we would put it in a fraction. [tex]\frac{135}{360}[/tex]

Last, multiply 16pi and 135/360 since we are taking a part of 16pi.

[tex]16\pi *\frac{135}{360}[/tex]

[tex]\frac{2160\pi}{360}[/tex]

[tex]6\pi[/tex]

Answer:

1/16

Step-by-step explanation:

Given the expression;

[tex]x^2+\dfrac{1}{2}x[/tex]

To find a constant that will make it a perfect square, we will use the square if the half of coefficient of x

Coefficient of x = 1/2

half of Coefficient of x = 1/2*(1/2)

Half of Coefficient of x = 1/4

square of the half of coefficient of x = (1/4)^2

square if the half of coefficient of x = 1/16

hence the constant that will make it a perfect square is 1/16

Answer:

The total number of pieces delivered in 6 days is the number delivered each second (28.52) times the number of seconds in 6 days (28 34.52). This gives:

(28.52) (28 3¹.52) 28 + 8.31.52+2 = 216.31.54

Answer: B. Break even point=(0.01)(# of points)(P) / monthly savings

Step-by-step explanation: took the quiz.

The formula for finding the break-even point is: Break-even point = Fixed costs ÷ (Unit price - Variable costs per unit).

The break-even point is the point at which a company's total revenue from sales equals its total costs, resulting in a profit of zero. There is no profit or loss at the break-even point.

The formula for finding the break-even point is:

Break-even point = Fixed costs ÷ (Unit price - Variable costs per unit)

Where:

Thus, the break-even point is the point at which the total revenue from sales equals the total costs, so there is neither a profit nor a loss.
