HeyxJacq

I do kinda get what you're doing, just not how you get the low point. I'm not the greatest at math :/ Thanks for the answer! So:

h = 1/225 a^2

h = 1/225 * 15^2

1/225 * 15^2 = 1/225 * 225 = 1

h = 1

and

- 30/225 * a + 1

- 30/225 * 15 + 1

- 2 + 1 = -1

h = -1

Thanks for the help already! Take your time (:

It is used to refer to the four quarters that are made when you devide the coordinate plane by the x and y axis

4 (x+7)^2 = 1

4x^2 + 56x + 196 = 1       Simplifying the equatation

4x2 + 56x + 195 = 0        Subtracting 1

(2x + 13) (2x + 15) = 0    Factorizing the left side

2x + 13 = 0   and   2x + 15 = 0

x = -13/2   or   x = -15/2

1. No error, because I believe it's an adverbial phrase of time so it should need a comma because it's at the beginning of the sentence.

2. Are difficult

Thank you CPhill! :")

Step one is simplifying the equatation!

(x+5/9)+5 = (7x-10/6)

x + 5/9 + 5 = 7x − 10/6

x + 5/9 + 5 = 7x + −5/3

x + 50/9 = 7x + −5/3

Step two is subtracting 7x from both sides

−6x + 50/9 −7x = −5/3

Step three is subtracting 50/9 from both sides

−6x = −65/9

Step four is dividing both sides by −6

−6x/−6 =−65/9/−6

x = 65/54

Now the second one! First we simplify the equatation.

x + 1/2 + 5 = 7x + −5/3

x + 11/2 = 7x + −5/3

Step two is to subtract 7x from both sides

−6x + 11/2 = −5/3

Step three is subtracting 11/2 from both sides

(−6x + 11/2 − 11/2 = −5/3 − 11/2)

−6x = −43/6

Now we divide both sides by −6

−6x/−6 = −43/6/−6

x = 43/36

Haha thanks CPhill!

2 goats = 8 legs

3 donkeys = 12 legs

4 chickens = 8 legs

8+12+8 = 16+12 = 28 legs

This is a calculator site, so you could actually save time and use the calculator yourself! But the answer is 231,28571429

1.2x = 6 you divide both sides by 1.2 and then you'll see that x = 5

A brief check; 1.2 x 5 = 6
