Answer:

x=2, y=2

Step-by-step explanation:

-2(3x+y=8)

3(2x+4y=12)

-6x+-2y=-16

6x+12y=36

0+10y=20

       y=2

3x+2=8

3x=6

x=2

  • 3x+y=8--(1)

2x+4y=12

  • x+2y=6--(2)

  • (1)×1 and (2)×3

\\ \rm\Rrightarrow 3x+y=8

\\ \rm\Rrightarrow 3x+6y=18

Subtract both

\\ \rm\Rrightarrow -5y=-10

\\ \rm\Rrightarrow y=\dfrac{-10}{-5}

\\ \rm\Rrightarrow y=2

Put the value in eq(2)

\\ \rm\Rrightarrow x+2(2)=6

\\ \rm\Rrightarrow x+4=6

\\ \rm\Rrightarrow x=6-4=2

What is value of x?<br> Enter your answer in the box.
marin [14]

Answer:

x \ = \ 10

Step-by-step explanation:

Let point D be the point where the straight line drawn from point A meets the straight line BC, it is evident that \triangle ABD and \triangle ACD is similar given that both triangles share the same angle, \angle BAD \ = \ \angle DAC. Hence, the ratio of the sides of each triangle is the same. Specifically,

                                              \displaystyle{\frac{x+4}{8} \ = \ \frac{2x+1}{12}}.

Performing cross multiplication yields

                                           12\left(x+4\right) \ = \ 8\left(2x+1\right) \\ \\ \rule{0.15cm}{0cm}12x+48 \ = \ 16x+8 \\ \\ \rule{1.1cm}{0cm} 4x \ = \ 40 \\ \\ \rule{1.3cm}{0cm} x \ = \ 10.

You are a real estate agent with ABC Real Estate company. You help sell a home for $155,000. The total commission is 6.5%. Your
gtnhenbr [62]

Answer:

$3,929.25.

Step-by-step explanation:

First, calculate the total commission.  That's found by multiplying the selling price ($155,000) by 0.065.  The result:  The total commission is $10,075.

Your company receives 60% of that.  So we multiply $10,075 by 0.60, obtaining $6,045.

Your share of the commission is 65% of that, so we multiply $6,045 by 0.65:

0.65($6,045) = $3,929.25.

Your personal share of the commission is thus $3,929.25.
