Answer:

I think 10.5 would be the unit price and 10lbs of potatoes and 2lbs of tomatoes would cost less

Step-by-step explanation:

since tomatoes cost 2 times more I decided to act as he only bought potatoes and in that case he would have bought 22lbs of potatoes so I divided 16.50 by 22 and got .75 then I multiplied it by 10 and got 7.5 as well as multiplied .75 by two to get the price of the tomatoes then I added 7.5+3 to get 10.5

Answer:

It can not be proved, so the last option

Step-by-step explanation:

Because there are no two angles in one triangle so it's not AAS or ASA. And there are no two sides so it's not SAS either.

Hi, umm pls help<br><br> 1/6(x-5)=1/2(x+6), solve for x <br><br> And can you please explain

Mumz [18]

Answer:

By solving the equation $\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ we found that $x=\frac{23}{2} \text { or }=11 \frac{1}{2}$

<u>Explanation: </u>

Given equation,

$\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ to find x

Step: 1 Cross multiply the denominators 2(x-5)=6(x+6)

Step: 2 Open brackets and simplify the term 2x-10=6x+36

Step: 3 Bring x terms on one side and simplify the equation the equation obtained is following,

2x-6x=36+10

-4x=46

$-x=\frac{46}{4}=\frac{23}{2}=11 \frac{1}{2}$

Therefore, we solved x value from the given equation $\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ as $x=\frac{23}{2} \text { or }=11 \frac{1}{2}$ .

Joan wants to make a dinner plan for next week.. How many different arrangements are there for the 7 d a y s ?

4vir4ik [10]

The number of arrangements is an illustration of permutations.

The number of arrangement is 5040

The given parameter is:

<em /> $n = 7$ <em> --- number of days</em>

<em /> $r = 7$ <em> --dinners for 7 days</em>

<em />

So, the number of different arrangement is

$^nP_r = \frac{n!}{(n - r)!}$

Substitute known values

$^7P_7 = \frac{7!}{(7 - 7)!}$

$^7P_7 = \frac{7!}{0!}$

$^7P_7 = \frac{5040}{1}$

$^7P_7 = 5040$

Hence, the number of arrangement is 5040
