First you want to change the 20% into a decimal which is .20
Next you want to multiply 90 by .20 because that will give you the answer for 20% of 90

Solve the proportion. s+1/4=4/8

Murrr4er [49]

5*s-(4*s)-(1/2) = -1/4-(4/8) // + -1/4-(4/8)

5*s-(4*s)-(1/2)-(-1/4)+4/8 = 0

5*s-4*s-1/2+1/4+4/8 = 0

s+1/4 = 0 // - 1/4

s = -1/4

s = -1/4

3/9 = 6/x

How do you solve -1x+20 is greater than -7+35

rusak2 [61]

$\huge\fbox{Hello~there!}$

Let's solve this inequality!

$\rm{-x+20>-7+35$

What can we do to solve this inequality? Well, first of all, we can add -7 and 35:

$\rm{-x+20>28$

Now, move 20 to the right, using the opposite operation:

$\rm{-x>28-20$

Subtract:

$\rm{-x>8$

Divide both sides by -1 to isolate x:

$\rm{x$ (Answer)

_____________

Additional comment

When we divide both sides of an inequality by a negative number, we flip the inequality sign.
