7 0

The equation given in the question is definitely solvable for finding the value of the unknown variable "x". There is only one unknown variable and one equation.The equation given in the question is
10/8 = (x - 10)/10
(10 * 10)/8 = (x - 10)
100 = 8(x - 10)
100 = 8x - 80
Reversing the two sides, we can write the equation as
8x = 100 + 80
8x = 180
x = 180/8
= 22.5
So the value of the unknown variable comes out to be equal to 22.5. I hope the procedure is clear enough for you to understand.

Use PEMDAS:

10/8= x- 10/10
⇒ 5/4= x- 1
⇒ x= 5/4+ 1
⇒ x= 5/4+ 4/4
⇒ x= 9/4
⇒ x= 2 1/4

Final answer: x= 2 1/4~

prisoha [69]

Answer:

$\%\ decrease = 9.52\%$

Step-by-step explanation:

Given

$Sales\ Price = \$209.99$

$Saved = \$20.00$

Required

Determine the %decrease

First, we need to determine the amount paid

$Amount = Sales\ Price - Amount\ Saved$

$Amount = \$209.99 - \$20.00$

$Amount = \$189.99$

The percentage decrease is the calculated as follows:

$\%\ decrease = -100\% * \frac{Final - Initial}{Initial}$

In this case;

$Initial = Sales\ Price = \$209.99$

$Final = Amount\ Paid = \$189.99$

So; we have:

$\%\ decrease = -100\% * \frac{189.99 - 209.99}{209.99}$

$\%\ decrease = -100\% * \frac{-20}{209.99}$

$\%\ decrease = 100\% * \frac{20}{209.99}$

$\%\ decrease = \frac{2000\%}{209.99}$

$\%\ decrease = 9.52426306015\%$

$\%\ decrease = 9.52\%$ (Approximated)

Which inequality is represented by the graph?

Taya2010 [7]

Answer:

Option B

Step-by-step explanation:

Notice that the region of the inequality is bounded by a line.

The first thing to do is find the equation of this line.

Note that the line intersects the x-axis at $x = 3.5$ and intercepts the y-axis at $y = -2.5$

We know that the equation of a line has the following form:

$y = mx + b$

Where m is the slope of the line and b is the intercept with the y axis.

So we already know that:

$b = -2.5 = -\frac{5}{2}$

Then we know that when $x = 3.5$ then $y = 0$

Thus:

$0 = 3.5m -2.5$

Ahroa we clear m.

$m = \frac{2.5}{3.5}\\\\m = \frac{5}{7}$

Then, the equation of the line is:

$y = \frac{5}{7}x -\frac{5}{2}$

We can also multiply by -2 both sides of the equation and we have:

$-2y = -\frac{10}{7}x +5$

Then:

$\frac{10}{7}x -2y =5$

The option that contains this equation is option B.

To verify it, enter a point within the shaded region, such as the point (0,0), in the selected inequality. If the inequality is satisfied then option B is correct

$\frac{10}{7}x -2y\leq5\\\\\frac{10}{7}(0) -2(0)\leq5\\\\0\leq5$

The inequality is satisfied because 0 is less than 5. Then the correct option is B
