Answer:

The 35 pound bag

Step-by-step explanation:

If you divide the price of the 25 pound bag by the number of pounds it has you get 0.81 dollars per pound

20.25 / 25 = 0.81

However if you divide the price of the 35 pound bag by the number of pounds it has you get 0.79 dollars per pound

27.65 / 35 = 0.79

This means you get more dog food for less in the larger 35 pound bag

Would anyone help With these questions it's the last one I don't know how to do them 1,2,3,4,5 and 6​
Shtirlitz [24]

Answer:

See below

Step-by-step explanation:

1.  Use x to designate the number of hours worked.

Plumber 1 = 35(x) + 25

Plumber 2 = 40(x)

Now you need to find when these two equations are equal to each other.

35(x) + 25 = 40(x)

Solve for x.

25 = 40x - 35x

25 = 5x

5 = x

So when the service call equals 5 hours, both plumbers will charge the same amount of money.

2.  Use x to designate the number of months.

Center 1 = 30x

Center 2 = 22x + 80 initiation fee

Now you need to make the two equations equal to each other and solve for x.

30x = 22x + 80

30x - 22x = 80    or 8x = 80

x = 10 months

3.  Use x to designate the pounds of the package

Shipper 1 = 14 + 2x

Shipper 2 = 20 + 1.5x

Make the two equations equal to each other.

14 + 2x = 20 + 1.5x

2x - 1.5x = 20 - 14

0.5x = 6

x = 12 pounds

4. Deanna $15 using $0.75 per game.  This means she can play a total of 20 games before having $0.

Lise $13 using $0.50 per game.  This means she can play a total of 26 games before having $0.

So since both end up with $0, you can see that Deanna would play 20 games and Lise would play 26 games.

5.  Use x to designate the call time length.

Hotel 1 = 1 + 0.80x

Hotel 2 = 2 + 0.75x

Make both equations equal to each other.

1 + 0.8x = 2 + 0.75x

0.8x - 0.75x = 2 - 1

0.05x = 1

x = 20

6.  Use x to designate semesters.

Duke = 22 + 6x

Kila = 4 + 12x

22 + 6x = 4 + 12x

22 - 4 = 12x - 6x

18 = 6x

3 = x semesters

How to solve: <img src="https://tex.z-dn.net/?f=log_%7B3%7D%20%28x%2B6%29%20%2B%20log_%7B3%7D%28x-6%29%20%3D%204" id="TexFormula
Shalnov [3]

Collapse the logarithms into one:

\log_3(x+6)+\log_3(x-6)=\log_3((x+6)(x-6))=4

Then write both sides as powers of 3:

3^{\log_3((x+6)(x-6))}=3^4

(x+6)(x-6)=81

Simplify the left side and solve for x:

x^2-36=81

x^2=117

x=\pm\sqrt{117}=\pm3\sqrt{13}

But we're not done yet. Notice that both x+6 and x-6 are negative when x=-3\sqrt{13}. We can't take the logarithm of a negative number (the result isn't real-valued, anyway), so we throw this solution out, and we're left with just

x=3\sqrt{13}
