AC and DB are the same length. Set the two to equal each other and solve for y.

9y + 1 = 8y +17

Subtract 8y from both sides:

y + 1 = 17

Subtract 1 from each side:

y = 16

Now you know Y you can find the the length of DB:

DB = 8y +17 = 8(16) +17 = 128 + 17 = 145

EB is half of DB:

EB = 145 / 2

EB = 72.5

Two classes have a total of 50 students. One class has 6 more students than the other. How may students are in the larger class
givi [52]
Subtract 6 from 50:
50-6 = 44
Divide 44 by 2:
44/2 = 22

add 6:

22+6 = 28

There is 22 in the smaller class and 28 in the larger class.

Consider the proof.
fiasKO [112]

Answer:

Correct choice is B

Step-by-step explanation:

In step 4 were proved that \triangle ABC\sim\triangle DEC.

By definition, similar triangles have proportional lengths of corresponding sides. To the side AB corresponds side ED, to the side AC corresponds side DC and to the side BC corresponds side EC. Thus,

\dfrac{AC}{DC}=\dfrac{BC}{EC}.
