Is it an S or is it supposed to be a 5 if S I think it's written like 8.5s? or something like that? Sorry not too good at this.

Blababa [14]

She will be able to fill 3 jars because 4/5=16/20 and 1/4 = 5/20 so 5/20 x 3 = 15/20

Simplify. y^-3 pls help me i need this very bad

prisoha [69]

My understanding is that when the power is a negative number, move it to the denominator and change it to positive.
In this case, the base is y, the power is -3
y^(-3)=1/(y^3)

Which represents the solution set to the inequality

Art [367]

$5.1(3 + 2.2x) \ \textgreater \ -14.25 - 6(1.7x + 4)$
Lets expand both multiplications first.
$15.3 + 11.22x \ \textgreater \ -14.25 - 10.2x - 24$
Simplify down the right side.
$15.3 + 11.22x \ \textgreater \ -38.25 - 10.2x$
Add 38.25 to both sides.
$53.55 + 11.22x \ \textgreater \ -10.2x$
Subtract 11.22x from both sides.
$53.55 \ \textgreater \ -21.42x$
Divide by -21.42 on both sides. Because we're dividing by a negative, we need to change the inequality direction.
$-2.5 \ \textless \ x$
This means, out of the options available, (-2.5, ∞) is the correct answer.
