Number 2 is wrong because it says NO more than so it would be the opposite of a more than sign. So it should be a less than or equal to sign.
The same goes for number 4.
Number 5 is wrong as well because since it is the maximum then it cannot be higher than 8, so there so be a less than or equal to sign.

2(x+5)+6x = 8x+10 One Solution No Solution Many Solutions

Mama L [17]

Step-by-step explanation:

2(x + 5) + 6x = 8x + 10

2x + 10 + 6x = 8x + 10

8x + 10 = 8x + 10

Since this equality is true for any real values of x, there are infinitely many solutions for x.

The best answer here is "Many Solutions".

One photo shop charges $0.36 per print. Another photo shop charges $2.52 plus $0.08 per print. Juan finds that the cost of print

koban [17]

Juan have to print 9 photos.

<u><em>Explanation</em></u>

Suppose, Juan have to print $x$ number of photos.

First photo shop charges $0.36 per print. So, the total cost to print $x$ number of photos in this shop $=0.36x$ dollar.

Second photo shop charges $2.52 plus $0.08 per print. So, the total cost for printing $x$ number of photos $= (2.52+0.08x) dollar$

As, the cost of printing is the same at both shops, so.....

$0.36x=2.52+0.08x\\ \\ 0.36x-0.08x= 2.52\\ \\ 0.28x=2.52\\ \\ x=\frac{2.52}{0.28}=9$

So, Juan have to print 9 photos.

Helen's house is located on a rectangular lot that is1 1-8 miles by 9/10 mile.Estimate the distance around the lot

klemol [59]

Answer: The distance around the lot is given by

$4\frac{1}{20}\ miles$

Step-by-step explanation:

Since we have given that

Length of rectangular lot is given by

$1\frac{1}{8}\\\\=\frac{9}{8}\ miles$

Width of rectangular lot is given by

$\frac{9}{10}\ mile$

We need to find the distance around the lot.

As we know the formula for "Perimeter of rectangle":

$Perimeter=2(Length+Width)\\\\Perimeter=2(\frac{9}{8}+\frac{9}{10})\\\\Perimeter=2(\frac{45+36}{40})\\\\Perimeter=2\times \frac{81}{40}\\\\Perimeter=\frac{81}{20}\\\\Perimeter=4\frac{1}{20}\ miles$

Hence, the distance around the lot is given by

$4\frac{1}{20}\ miles$
