Question

Marcie wants to enclose her yard with a fence. Her yard is in the shape of a rectangle attached to a triangle. The formula for the area of the enclosed space is A = lw + 0.5bh. Solve for b.

Answer 1

All its asking you to do is get b by itself

Answer 2

to do that you first want to subtract lw from both sides you get. A-lw=.5bh

Answer 3

then you dived both sides by .5h that leaves you with b=a-lw/.5h

Answer 4

i dont understand

Answer 5

have you learned how to cancel out terms yet?

Answer 6

no i'm in 8th grade

Answer 7

ok well in order to move a variable to the other side you have to use the opposite sign

Answer 8

so you would subtract

Answer 9

A = lw + 0.5bh
to get lw to the other side you subtract lw to both sides that get read of it one one side so know you have a-lw=.5bh

Answer 10

since you are multiplying .5bh the opposite sign would be division. so divide .5h from both sides because you need b all by itself on one side

Answer 11

that leaves you with a-lw/.5h=b
do you get it now?

Answer 12

kind of i think

Answer 13

so what do you not get so i can explain it some more?

Answer 14

so my answer is
b = A divided by the quantity l times w plus 0.5 times h

Answer 15

almost instead of plus 0.5 time h it would be divided by 0.5 times h

Answer 16

so its
b = The quantity A minus l times w all divided by 0.5 times h

Answer 17

yes you got it

Answer 18

yay thank you so much

Answer 19

youre awesome!

Answer 20

your welcome, no problem. Thank you your cool too
