## anonymous one year ago Someone please help me step by step i've been stuck on this and i want to learn 1. D = 1/25fh solve for f 2. D = p(3 + nr) solve for r

1. precal

2. precal

D=1/25fh is fh a denominator?

3. precal

$D=\frac{ 1 }{ 25fh}$

4. anonymous

no its just next to 1/25

5. precal

ok multiply 25 to both sides first

6. anonymous

25D = fh ?

7. precal

then divide h to both sides

8. precal

correct so far

9. anonymous

25d/h = f

10. anonymous

so, f = 25d/h

11. precal

yes

12. precal

sorry gotta go

13. anonymous

Thankkks! can you help me with the second one?
