12 is 60% of 20. You can make 60% into a fraction (60/100) and set that fraction equal to 12/x. You then cross multiply (12*100 and 60*x) to get 1200=60x. You then divide both sides by 60 to get x, which equals 20.

Answer:

The statement is True!

Step-by-step explanation:

Clare paid full price for an item.

Let Price of the item = x

Han bought the same item for 80% of the full price.

Han bought it for 0.8x

Clare said, I cants believe I paid 125% of what you paid, Han!

The above statement is True if;

125% of 0.8x = x

1.25 * 0.8x = x

x =x

The statement is True!

Graph and write solution:<br><br> 2x + 1 = y<br><br> -4x + 6y = -10

PIT_PIT [208]

The graph is shown in figure below

The Solution Set is (-2,-3)

Step-by-step explanation:

We need to graph the equations and writ the solution.

For graphing we need to find the values of x and y.

For that, we need to solve the given equations:

$2x + 1 = y\\-4x + 6y = -10$

Let:

$2x + 1 = y\,\,\,eq(1)\\-4x + 6y = -10\,\,\,eq(2)$

We can solve this by using Substitution Method.

Putting value of y of eq(1) into eq(2) and finding value of x:

$2x + 1 = y\,\,\,eq(1)\\-4x+6(2x+1)=-10\\-4x+12x+6=-10\\8x+6=-10\\8x=-10-6\\8x=-16\\x=-16/8\\x=-2$

So, value of x = -2

Now put value of x in eq(1) to find value of y:

$2x + 1 = y\\2(-2)+1=y\\-4+1=y\\y=-3$

So, value of y = -3

Plotting on graph: x=-2 and y = -3

The graph is shown in figure below

The Solution Set is (-2,-3)
