Answer:

16

Step-by-step explanation:

AC= 15x+2

BD= 9x+14

AE= 1/2AC

AC=BD

1) First we must find what x is. Because AC and BD are the same length, we can set them equal to each other to find x.

15x+2=9x+14

6x=12

x=2

2) Now that we know x, we plug the value for x back into the equation for AC.

AC=15x+2

AC=15(2)+2

AC=30 +2

AC= 32

3) Finally, we can find AE because it is half of AC.

AE=1/2AC

AE=1/2(32)

AE=16

hope this helps!! :)

In the system of equations below, which variable would it be easiest to solve for? x + 4 y = 14. 3 x + 2 y = 12 The easiest to s
Murljashka [212]

Answer:

<h2>The easiest to solve for is x in the first equation</h2>

Step-by-step explanation:

Given the system of equation, x + 4 y = 14. and 3 x + 2 y = 12, to solve for x, we can use the elimination method of solving simultaneous equation. We need to get y first.

x + 4 y = 14............ 1 * 3

3 x + 2 y = 12 ............ 2  * 1

Lets eliminate x first. Multiply equation 1 by 3 and subtract from equation 2.

3x + 12 y = 42.

3 x + 2 y = 12

Taking the diffrence;

12-2y =42 - 12

10y = 30

y = 3

From equation 1, x = 14-4y

x = 14-4(3)

x = 14-12

x = 2

It can be seen that the easiest way to get the value of x is by using the first equation and we are able to do the substitute easily <u>because the variable x has no coefficient in equation 1 compare to equation 2 </u>as such it will be easier to make the substitute for x in the first equation.
