Answer:

AB = 8

Step-by-step explanation:

AC = 36

AB/BC = 2/7

AB = (2/7)BC

AB + BC = 36

(2/7)BC + BC = 36

(9/7)BC = 36

BC = 36(7/9)

BC = 4*7

BC = 28

AB + BC = 36

AB = 36 - 28

AB = 8

======

Is AB/BC = 2/7?

8/28 = 2/7  YES

Make y the subject of these equations.<br> by² = d<br> Jay = 6<br> ay - cy = d.<br> cy - b) = y
allsm [11]

Answer:

See all the answers  below.

Step-by-step explanation:

by² = d

Jay = 6

ay - cy = d.

cy - b) = y

Option A

by² = d

divide both side by b

y² = d/b

square both sides

y=√d/b

Option B

Jay = 6

Divide both sides by Ja

y= 6/Ja

Option C

ay - cy = d

y(a-c)=d

divide both sides by (a-c)

y= d/(a-c)

Option D

(cy - b) = y

y-cy=-b

y(1-c)=-b

y= -b/(1-c)

The short sides of a rectangle are 2 inches. The long sides of the same rectangle are three less than an unknown
Brums [2.3K]

Answer:

The first student is correct

Step-by-step explanation:

With the given information there is already 4 inches on the rectangle. 13 x2 = 26. 26+4=30. For student two if the unknown number was 10 it would not work because the longest side is 3 less then the unknown number. 10-3=7. 7x2=14. 14+4= 28<30
