Answer:

Step-by-step explanation:

$20 - \frac{x}{3} = \frac{x}{2}$

Multiply through by the LCM that's 6 in order to eliminate the fraction

That's

$6 \times 20 - 6 \times \frac{x}{3} = 6 \times \frac{x}{2} \\ 120 - 2x = 3x$

Using the addition property add 2x to both sides of the equation

That's

$3x + 2x = 120 + 2x - 2x \\ 5x = 120$

<u>Divide both sides by 5</u>

$\frac{5x}{5} = \frac{120}{5}$

We have the final answer as

Hope this helps you

Solve each system of equations by writing a new system that eliminates one of the variables.

Answer:

$x=33\\y=-41$

Step-by-step explanation:

Let:

$2x+y=25\hspace{5}(1)\\and\\4x+3y=9\hspace{5}(2)$

We need to eliminate one of the variables, so let's use elimination method. First multiply (1) by 2

$2*(1)\equiv\hspace{5}4x+2y=50$

Now subtract (2) from 2*(1) in order to eliminate x:

$2*(1)-(2)\\4x-4x+2y-3y=50-9\\-y=41$

Solving for y:

Multiplying both sides by -1

$y=-41$

Finally, replacing the value of y in (1)

$2x-41=25$

Solving for x:

add 41 to both sides:

$2x=66$

Multiply both sides by 1/2:

$x=\frac{66}{2} =33$

for a different pizza dough recipe, the equation f=2.5w represents the number of cups of flour, f, that you need for w cups of w

zhuklara [117]

For any direct variation, the equation is of the form y = kx, where k is the constant of proportionality.

Given the equation: f = 2.5w

The constant of proportionality is 2.5.

This means that the ration of the cups of flour to the cups of water used in the recipe is 2.5

Answer:

g(x) = 1.1f(x + 1)

Step-by-step explanation:

g(x) is the translation of the parent function f(x) to left by 1 unit and slightly stretched vertically.

f(x) = 1.1f(x + 1)
