Answer:

\huge\boxed{\sf x = 8a}

Step-by-step explanation:

\sf \frac{3}{a} x - 4 = 20\\\\Add \ 4 \ to \ both \ sides\\\\\frac{3}{a} x = 20+4\\\\\frac{3}{a} x = 24\\\\Multiply \ both \ sides \ by \ a\\\\3x = 24 * a\\\\Divide \ 3 \ to \ both \ sides\\\\x = 24a / 3\\\\x = 8a\\\\\rule[225]{225}{2}

Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation.
hammer [34]

Answer: option d.

Step-by-step explanation:

If <em>y </em>varies directly as <em>x</em> and <em>z</em>, the form of the equation is:

y=kxz

Where<em> k</em> is the constant of variation.

If y=4 when x=6 and z=1 then substitute these values into the expression and solve for <em>k:</em>

4=k(6)(1)\\4=6k\\k=\frac{4}{6}\\\\k=\frac{2}{3}

<em> </em>Substitute the value of <em>k</em>  into the expression. Then, the equation is:

y=\frac{2}{3}xz

To find the value of <em>y </em>when x=7 and z=4, you must substute these values into the equation. Therefore you obtain:

y=k=\frac{2}{3}(7)(4)

y(7,4)=\frac{56}{3}

Steven has $25 dollars to spend. He spent $10.81, including tax, to buy a new DVD. He needs to save $10.00 but he wants to buy a
Yuliya22 [10]

(25 - 10.81) - 1.38p = 10

p = package of peanuts  

25 - 10.81 = 14.19

14.19 - 1.38p = 10

Subtract 14.19 from each side

10 - 14.19 = -4.19

-1.38p = -4.19

Divide both sides by -1.38

p = 3 (roughly, but because you can only buy the whole package, this is the amount you can buy)

He can buy a maximum of 3 packages of peanuts.

10 11 10 y 10 8<br><br> If the mean is 10 what number could y be?
murzikaleks [220]
To find the mean of a number sequence, add all the numbers together and divide them by the number of numbers used...

10 + 11 + 10 + 10 + 8 = 49

49 ÷ 5 = 9.8

The mean does not match 10, so make up numbers untill it matches.

10 + 11 + 10 + 10 + 8 + 6 ÷ 6

= 10 !

The anwser would be y = 6
