Ulleksa [173]1 year ago
5 0

Solution:

Given the system;

\begin{gathered} 4x+6y=32.............equation1 \\  \\ 3x-6y=3..............equation2 \end{gathered}

Add equation1 to equation2, we have;

\begin{gathered} 4x+3x+6y-6y=32+3 \\  \\ 7x=35 \\  \\ \frac{7x}{7}=\frac{35}{7} \\  \\ x=5 \end{gathered}

Substitute x = 5 in equation2;

\begin{gathered} 3x-6y=3 \\  \\ 3(5)-6y=3 \\  \\ 15-6y=3 \\  \\ 6y=15-3 \\  \\ 6y=12 \\  \\ y=2 \end{gathered}

ANSWER:

x=5,y=2

Can somebody explain step by step ?
lukranit [14]

Answer:

3m\sqrt[5]{2m^4p^4}

Step-by-step explanation:

We want to find the fifth root of 486m^9p^4. In order to do so, we need to factorise

Let's factorise 486 first:

486 = 2 * 243 = 2 * 3^5

Ah, we see that 3^5 can be taken out and becomes 3 outside of the 5th root since the 5th root of

Now look at the variables. We see that since we have p^"4", whose exponent is less than 5, it's impossible for us to write it as a power of 5, so we leave this in the root.

We also have m^"9", which can be written as m^"5" * m^"4". Again, we see that the m^"4" term will have to remain inside the root, but we can take out the m^"5", which becomes m.

Our final answer is thus: 3m\sqrt[5]{2m^4p^4}.

On a piece of paper, use a protractor and a ruler to construct △ABC with AB=4 in., AC=4 in., and m∠A=60°.
ollegr [7]

Answer:

BC 4 in

Step-by-step explanation:

The steps for construction;

  • Using a ruler draw line AB 4 inches  and label the end points A and B
  • At point A , using a protractor, measure angle 60° and mark with point. Draw a line from A passing through this point extending to a length of 4 inches
  • Mark that point C.
  • Using the ruler, join point C and B and measure BC.

From calculation, length BC can be found by the formula;

BC=\sqrt{a^2+b^2-2*a*b*cosA}------where a=b=4 in , cos A = cos 60°

BC=\sqrt{4^2+4^2-2*4*4*cos60}

BC = 4 in
