Answer:
d = 12800/f
Step-by-step explanation:
variation of proportion is 256(50) = 12,800
d = 12800/f
84÷2.8 =3.0 that's what I did when I learned it
Add the numbers: 3+17 = 20
-x + 5 < -1/20
Apply the fraction rule: -a/b = - a/b
-x + 5 < - 1/20
Subtract 5 from both sides
-x + 5 - 5 < 1/20 - 5
Simplify
-x< - 101/20
Multiply both sides by -1 (reverse the inequality)
(-x) (-1) > (-101/20) (-1)
x> 101/20 is the final answer
