What is the solution to the equation 4x-6= 10x-3?

Lelechka [254]

Answer:

To solve this equation we need to get x by itself.

4x-6=10x-3, (the first step would be adding 6 to both sides.)

4x=10x+3 (the next step is the subtract ten from both sides.)

-6x=3 (Last step is the divide both sides by -6.)

x=-1/2

Hope this helps ;)

Andrea bought 1 2/5 pounds of avocados at $4.20 per pound and 2 1/

Answer:

$14.43¢

Step-by-step explanation:

We are given; $1\frac{2}{5}$ pounds, 1 pound = $4.20 and $2\frac{1}{4}$ pounds,1 pound = $3.80 that Andrea bought.

Now we need to find her total cost. To do that, we must first find the cost of the avocados. To do so, let us set up a graph. But before that is done, convert $1\frac{2}{5}$ to a decimal. It is 1.4. Now we can set up a graph.

Avocados

$\frac{4.2}{1}=\frac{x}{1.4}$

Switch sides

$\frac{x}{1.4}=\frac{4.2}{1}$

Apply rule: $\frac{a}{1}=a$

$\frac{x}{1.4}=4.2$

Multiply both sides by 1.4

$\frac{1.4x}{1.4}=4.2\cdot \:1.4$

Simplify

$x=5.88$

So, her cost for avocados is $5.88¢

Now we must first find the cost of the avocados. To do so, let us set up a graph. But before that is done, convert $2\frac{1}{4}$ to a decimal. It is 2.25. Now we can set up a graph.

$\frac{3.8}{1}=\frac{x}{2.25}$
