Why is the number 6 scared of the number 7?

Lady_Fox [76]

This is a well known joke:

Why six afraid of seven? Because seven ate nine!

It is supposed to be a "word game" where instead of writing eight, the authour wrote ate, which sound the same but means something different.

Hope it helped,

Happy homework/ study/ exam!

Find the solution of the system of equations.<br> 10x+10y=40 <br> 5x+3y=8

ddd [48]

Answer:

x = -2 & y = 6

Step-by-step explanation:

$10x+10y=40$

$10x+10y+ -10y=40+-10y$

$10x=-10y+40$

$\frac{10x}{10} =\frac{-10y+40}{10}$

$x=-y+4$

$5x+3y=8$

$5(-y+4)+3y=8$

$-2y+20=8$

$-2y+20+-20=8+-20$

$-2y=-12$

$\div2$

$y=6$

$x=-y+4$

$x=-6+4$

$x=-2$

Hope this helps.

Mr. Gonzazales has only 42.50 to spend he wants to buy 29 t shirts including tax and some bracelets that cost 4.50 each includin

erica [24]

Answer:

He can buy <u>3 bracelets</u>.

Step-by-step explanation:

Given:

Mr. Gonzales has only 42.50 to spend he wants to buy 29 t shirts including tax and some bracelets that cost 4.50 each including tax.

Now, to find the number of bracelets he can buy.

Let the number of bracelets he can buy be $x.$

Price of each bracelets = 4.50.

Total amount to spend = 42.50.

Number of t-shirts = 29.

Now, to get the number of bracelets we put an equation:

$29+4.50\times x=42.50\\\\29+4.50x=42.50$

<em>Subtracting both sides by 29 we get:</em>

<em /> $4.50x=42.50-29\\\\4.50x=13.5$ <em />

<em>Dividing both sides by 4.50 we get:</em>

$x=3.$

<u>The number of bracelets = 3.</u>

Therefore, he can buy 3 bracelets.
