Answer:
Divide by rt on both sides
a) \: p = \frac{i}{rt}
Subtract 2L from both sides
b) \: m = 9 - 2l
Subtract 9 then multiply by 4
c) \: x = 4(2k - 9) = 8k - 36Multiply by K
d) \: p = rk
Step-by-step explanation:
Profit=15
Because-
45-30=15
x=36
17+3 =20
now we have :
x+4
___ = 20
2
20*2= 40
x+4=40
