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

Kara earned $136.75 last week working 16 hours. She earned $10.50 per hour at the fast food restaurant and $4.25 per hour helpin
Evgesh-ka [11]

Answer:

ANSWER: she worked 11 hours at the fast food restaurant and 5 hours helping her aunt

Step-by-step explanation:

First we are going to try to find how many hours she worked on the fast food restaurant so you multiply 4.25 time 16 and x

10.50x + 4.25(16-x) =136.75

10.50x + 68 - 4.25x= 136.75

Then, you subtract 68 from both sides and subtract 4.25x from 10.50x

6.25x=68.75

Divide

X=11 that is how many hours she worked at the FAST FOOD RESTAURANT

Then 16-11 and that gives us how many hours she helped her aunt.
