Help with this proof
mixer [17]
Essentially, what we need to do here is prove that BE=EC, BE=CB, and.or CE=BC therefore making it isosceles. With ∠AEC=∠DEB, we know AE=DE, so EC=EB (the points go in order). Therefore, as EC=EB, BEC is isosceles (it has at least 2 equal sides).

Find the solution to the system of equations.<br> x + y + z = 25<br> y+z= 18<br> Z= 7
Umnica [9.8K]

Answer:

x=7

y=11

z=7

Step-by-step explanation:

x + y + z = 25

y+z= 18

Z= 7

Substitute the third equation into the second

y+z=18

y+7 = 18

y = 18-7

y = 11

Now substitute y=11 and z=7 into the first

x +y+z = 25

x+11+7 = 25

x+18 = 25

x = 25-18

x=7

9. Kelly rode her bike 3 miles less than twice the number of miles Jon rode. Together
prohojiy [21]

Answer:

Jon rode <u>17 miles</u> and Kelly rode <u>31 miles</u>.

Step-by-step explanation:

Given:

Kelly rode her bike 3 miles less than twice the number of miles Jon rode.

Together  they rode 48 miles.

Now, to find the miles they each ride.

<em>Let the number of miles Jon rode be </em>x.<em />

<em>So, the number of miles Kelly rode is</em> 2x-3.

Together they rode = 48 miles.

Now, to get the miles they each rode:

According to question:

x+(2x+3)=48

x+2x-3=48

3x-3=48

<em>Adding both sides by 3 we get:</em>

3x=51

<em>Dividing both sides by 3 we get:</em>

x=17.

<em>Jon rode = 17 miles.</em>

So, to get the miles Kelly rode we substitute the value of x:

<em>And Kelly rode = </em>2x+3<em />

=2\times 17-3

=34-3

=31\ miles.

Therefore, Jon rode 17 miles and Kelly rode 31 miles.
