Answer: x = 49/12

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5x+7x+6−26=29

5x+7x+6+−26=29

(5x+7x)+(6+−26)=29(Combine Like Terms)

12x+−20=29

12x−20=29

Step 2: Add 20 to both sides.

12x−20+20=29+20

12x=49

Step 3: Divide both sides by 12.

12x/12 = 49/12

Answer:

The price of CD's = $15

The price of deluxe bundles = $85

The price of premium bundles. = $ 35 ....

Step-by-step explanation:

Let c represents the number of CD's

Let d represents the number of deluxe bundles

Let p represents the number of premium bundles.

Now according to the given statement:

c = $15

d = c+2p =

d = 15+2p --------equation 1

455c+87p+35d = $12,845 --------equation 2

Now substitute the value of d in equation 2 to find the value of p

455c+87p+35d = $12,845

455(15)+87p+35(15+2p) = $12,845

6825+87p+525+70p=$12,845

Now combine the like terms:

6825+157p+525 = $12,845

Now shift all the like terms to the R.H.S

157p= 12845-6825-525

157p = 5495

Divide both sides by 157

157p/157 = 5495/157

p = 35

Now substitute the value p =35 in equation 1.

d = 15+ 2p

d = 15+2(35)

d = 15+70

d = 85

Therefore we have found that,

The price of CD's = $15

The price of deluxe bundles = $85

The price of premium bundles. = $ 35 ....

Please help i really need help <br> thanks

Answer:

B. 31.62

Step-by-step explanation:

First, find the distance of the line using the distance formula, $d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1} )^2 }$ . Plug the two points (-1,0) and (5,2) into the formula and solve. This gives you 6.32, then this is only one line of a pentagon, which has 5 sides, so you need to multiply. Since you are finding the perimeter, which is all of the sides added together, multiply the one side by 5. 6.32*5=31.62.
