BD=16 and ÁT is the<br> perpendicular bisector of BD. Y=?

iren2701 [21]

Answer:

$y= 5$

Step-by-step explanation:

Given

$BD = 16$

$BC = 2y - 2$

$CD = y + 3$

Required

Find y

$BD = BC + CD$

So, the expression becomes

$16 = 2y - 2 + y + 3$

Collect like terms

$16 = 2y + y- 2 + 3$

$16 = 3y+1$

Collect like terms

$3y = 16 - 1$

$3y = 15$

Make y the subject

$y= 15/3$

$y= 5$

Usimov [2.4K]

Answer & Step-by-step explanation:

n represents our number. So, twice a number would be 2n because twice means multiply by two.

When the problem says 6 less, then it means 6 less than 2n. So, it would look like 2n-6.

FInally, the problem says that all of this equals 17 so 17 would be the result.

So, you answer is 2n-6 = 17. This is answer choice B.
