Answer: x = 14

Step-by-step explanation: you can solve this two different ways. By using corresponding angles or vertical angles. Either way, the angles will sum to 180 either by linear pairs or by same side interior angles.

(5x-14) + (8x+12) = 180. Combine like terms.

13x-2 = 180. Add 2 to both sides. 13x = 182. Divide both sides by 13. X = 14.

What is 6.7086 rounded to the nearest tenth
padilas [110]
Hello!

Decimals used to confuse me a lot! :D 

When a question asks to round the decimal to the "nearest tenth", it simply means to round it to one decimal place.

6.7086 would be rounded to 6.7 if we round it to the nearest tenth. See, the 7 is in one place after the decimal point. 

The best way to understand decimal places, in my opinion, is to search up a tenths, hundredths, thousandths, etc. chart. Hope this gave you a better understanding of decimal places!

Find the distance between the given points: (2, -2) and (-4, 7)
sasho [114]

Answer:

3\sqrt{13}

Step-by-step explanation:

Hi there!

We want to find the distance between the points (2, -2) and (-4, 7).

To do that, we can use the distance formula.

The distance formula is given as \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}, where (x_1, y_1) and (x_2, y_2) are points

We have everything needed to find the distance, but let's label the values of the points to avoid any confusion

x_1=2\\y_1=-2\\x_2=-4\\y_2=7

Now substitute those values into the formula and solve

\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

\sqrt{(-4-2)^2+(7--2)^2}

Simplify

\sqrt{(-4-2)^2+(7+2)^2}

\sqrt{(-6)^2+(9)^2}

Square the numbers under the radical

\sqrt{36+81}

Add the numbers under the radical together

\sqrt{117}

Simplify the square root

3\sqrt{13}

Hope this helps!

Sauron [17]

Answer:

<h2>2 in each box of course</h2>

g= green chips       r= red chips

3 boxes of green chips meaning for each box there are <em>2</em> chips so there are 6 green chips. 5 boxes of red chips meaning for each box there are two chips so there are 10 red chips and 6 g + 10r = 16 chips in total
