Answers

6x=4.50
x = price per container
x=4.50 / 6
x= .75 per container
.75 * 8containeers = $6

$6. You just divide $4.50 by 6, then multiply your answer by 8.

2x = -5
x = -5/2
x = -2.5

If y varies jointly with x and z and y=13 when x=26 and z=6 find x when y=25 and z=18

Answers

Step-by-step explanation:

as I can see this the answer is

x = 25/78

in decimal

x = 0.320

Final answer:

The problem involves joint variation with variables y, x, and z. After finding the constant of variation, we substitute the given values into the joint variation equation and determine that x = 16.67

Explanation:

First, we establish the equation of joint variation, which in this context is y = kxz, where 'k' is the constant of variation. When y=13, x=26, and z=6, we insert these values into the equation to solve for 'k'. This gives us k = y/(xz) = 13/(26*6) = 0.08333.

Now that we have the constant 'k', we can find the value of 'x' when y=25 and z=18. We rearrange our equation to solve for 'x', resulting in x = y/(kz). Substituting the known values, we get x = 25/(0.08333*18) = 25/1.5 = 16.67. Therefore, if y varies jointly with x and z, and y=25 when z=18, then x = 16.67.
