frutty [35]

Answer:

Step-by-step explanation:

Change the 2/3 to 4/6

Now the ratio becomes 3:4:6

So the number of each is

3x + 4x + 6x = 520

13x = 520

x = 40

Red = 3*40 =      120

Yellow = 4*40 = 160

Blue = 6 * 40  = 240

Total =               520

bagirrra123 [75]

Answer:

b. 360

Step-by-step explanation:

If they are getting 180 packages and each case has 12 packages then you would need to do 180/12 to get the amount of cases they are buying aka 15 cases. 2 packages cost $48 so 1 package would cost $28. Then you would do $28 times 15cases and get $360

In more # and less words

180/12=15  getting 15 cases

48/2=24 cost of 1 case

15(24)=320 The total amount

I hope this helped!

PLEASEE HELP ME, ITS JUST ONE PROBLEM, PLEASE HELPPPP <3<3 !!!
Simora [160]

We can see that the function passes through the point (2,-1). This implies that

\log_b(2)=-1

or, equivalently,

b^{-1}=2 \iff \dfrac{1}{b}=2 \iff b=\dfrac{1}{2}

The same conclusion could have been reached by observing that the function passes through \left(\frac{1}{2},1\right)
