Which ordered pair is the solution to the system of equations? {x+3y=-12, y= 1/3x-6?

Mathematics

Julli [10]3 years ago

For this, I'll be using the substitution method. Since y = 1/3x - 6, replace the y variable in the first equation with 1/3x - 6 and solve for x:

x+3(\frac{1}{3}x-6)=-12\\ x+x-18=-12\\ 2x-18=-12\\ 2x=6\\ x=3

Now that we have the value of x, plug it into either equation to solve for y:

3+3y=-12\\ 3y=-15\\ y=-5\\ \\ y=\frac{1}{3}*3-6\\ y=1-6\\ y=-5

<h3><u>In short, the solution to this equation is (3,-5).</u></h3>

Answer: 140%

Step-by-step explanation:

Cost of the coats = $45 each

Selling price of the coat = $63 each

The percent of the purchase price that is the sales price would be:

= 63/45 × 100

= 7/5 × 100

= 140%

Therefore, the answer is 140%.

ΔABC is an isosceles triangle with AB = BC= 6 units. D and E are the midpoints or AB and BC, respectively. The length of AC is 8
nydimaria [60]
There are two triangles that exist in this problem. First is the given triangle ABC, witch AB = BC = 6 and AC = 8
Next is the smaller triangle formed by connecting points D and E; triangle EAD, with EA = AD = 3 and the length of DE is unknown.
Because these triangles are similar, a simple ratio may be set up in order to calculate DE.
DE / AC = EA / AB
DE = 3/6 * 8
DE = 4 units

What is 0.482 repeating as a simplified fraction?
weeeeeb [17]

the idea being, we multiply the value by some power of 10 just to move the repeating digits to the left of the decimal point.  We have 3 digits, we'll use 1000, anyhow, without further adieu,


\bf \begin{array}{|ccl|ll}&#10;\cline{1-3}&#10;\stackrel{\qquad}{x=0.\overline{482}}&&\\&#10;\cline{1-3}&#10;&&\\&#10;\stackrel{\textit{3 digits, we use 3 zeros}}{1000\cdot x}&=&482.\overline{482}\\&#10;&&482+0.\overline{482}\\&#10;&&482+x\\&#10;&&\\&#10;\cline{1-3}&#10;\end{array}\implies 1000x=482+x&#10;\\\\\\&#10;999x=482\implies x=\cfrac{482}{999}
