Question

4. Marcie wants to enclose her yard with a fence. Her yard is in the shape of a triangle attached to a rectangle. See the figure below.


The area of this figure can be found by the formula A = (wh) + 0.5(bh). If Marcie wants the total area to be larger than a specified value, she can use the formula A > (wh)+ 0.5(bh). Rewrite this formula to solve for b. Show all steps in your work.

Answer 2

A > (wh)+ 0.5(bh)

they want u solve b here

Answer 3

first isolate b like u wud normally, when solving an equation

Answer 4

A > (wh)+ 0.5(bh)

subtract (wh) both sides

A > (wh)+ 0.5(bh)
-(wh) -(wh)

Answer 5

wat do u get after that ?

Answer 6

a - wh > + 0.5(bh)?...

Answer 7

Yes !

Answer 8

thats the answer? :o

Answer 9

A > (wh)+ 0.5(bh)

subtract (wh) both sides

A > (wh)+ 0.5(bh)
-(wh) -(wh)

A-wh > 0.5(bh)

divide both sides by 0.5h
A-wh
------- > b
0.5h


or

A-wh
b < -------
0.5h

Answer 10

does that makes sense, how that > has become < ? :)

Answer 11

yes, thank you soo much.

Answer 12

good, you're wlcme :)
