It is true, except when x = 2/5, since it is an asymptote.

Step-by-step explanation:

3x=5xy-2y

3x=y(5x-2)

3x/5x-2=y

5x-2=0 -------> 5x=2 --------> x=2/5

A contractor purchases ceramic tile to remodel a kitchen floor. Each tile costs $4.00, and the adhesive and grouting material ne

Kazeer [188]

Answer:

160 tiles.

Step-by-step explanation:

First let's make an equation.

Each tile costs $4, let's make t=number of tiles.

+$15.82, and the total cost being $655.82

So ideally our equation would look like

4t+15.82=655.82

Now solve.

First, subtract 15.82 on both sides.

4t=640

Second, divide 4 on both sides to make the variable t by itself.

t=160

So, the contractor purchased 160 tiles.

100 points!!!! Solve for a 7a - 2b = 5a + b a = 2b a = 3b a = 3/2b a=2/3b

Llana [10]

Answer:

Therefore solution for a is

$a=\frac{3b}{2}$

Step-by-step explanation:

Given:

7a - 2b = 5a + b

To Find:

a = ?

Solution:

7a - 2b = 5a + b .................Given

First take all the 'a' terms to the left hand side and 'b' terms to the right-hand side of the equation,

∴ $7a-5a=2b+b\\\\2a=3b$

Now dividing by 2 on both the side we get

∴ $\frac{2a}{2} =\frac{3b}{2} \\\\\therefore a=\frac{3b}{2}$

Therefore solution for a is

$a=\frac{3b}{2}$

Caroline rolls a fair dice 480 times. How many times would Caroline expect to roll a six?

Gnom [1K]

A fair die has 6 sides so a 1/6 chance for each number
So divide 480/6= 80
80 times for each number, 80 for 6
