If AC = 3, BC = 5, and AB = 7, find AD:<br> 2 5/8<br> 4 1/5<br> 4 3/8<br> 11 2/3
Vesna [10]

Answer:

1.  2\frac{5}{8}  

Step-by-step explanation:

We can see that CD is angle bisector, So we will use angle bisector theorem which states that the angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle.

We can set up an equation as:  

\frac{AC}{AD}=\frac{BC}{BD}

Upon substituting our given values we will get,

\frac{3}{AD}=\frac{5}{(7-AD)}}

Cross multiplying our equation we will get,

5AD=3*(7-AD)

5AD=21-3AD

5AD+3AD=21

8AD=21

AD=\frac{21}{8}

AD=2\frac{5}{8}

Therefore, the length of AD is 2\frac{5}{8} units and 1st option is the correct choice.

Solve each system substitution 6x - 12y=24 And -x - 6y=4
almond37 [142]
6x-12y=24
x=-6y-4
6(-6y-4)-12y=24
-36y-24-12y=24
-48y=48
y=-1
6x-12(-1)=24
6x+12=24
6x=12
x=2

6(2)-12(-1)=24
12+12=24
 24=24 true
and
-(2)-6(-1)=4
-2+ 6=4
4=4 true

PLZ HELP ill GIVE BRAINIESt!!!!20 Points
shepuryov [24]
She made her mistake at the first step. To simplify a radical, you would find two numbers that multiply by each other to get your original number (under the radical) and have one of the number be a perfect square.

Her reasoning is wrong because 10*10 is not \sqrt{50}. Had she been correct, her answer should have been able to be squared to equal \sqrt{50}

In other words, she should have done \sqrt{25*2}= \sqrt{25} * \sqrt{2}=5 \sqrt{2}
(We used 25 because 25 is a perfect square, 5*5=25).
