Answer:

-x<3 is the same as x>-3 because when you divide -x<3 by -1 on both sides it ends up as x>-3. (They're the same thing just one isn't simplified.)

Answer:

$\left(s\cdot t\right)\left(x\right)=2x^2+12x+16$

$\left(s-t\right)\left(x\right)=-x$

$\left(s+t\right)\left(4\right)=20$

Step-by-step explanation:

Given functions are:

$s\left(x\right)=x+4$

$t\left(x\right)=2x+4$

Then $\left(s\cdot t\right)\left(x\right)=s\left(x\right)\cdot t\left(x\right)$

or $\left(s\cdot t\right)\left(x\right)=\left(x+4\right)\left(2x+4\right)$

or $\left(s\cdot t\right)\left(x\right)=2x^2+4x+8x+16$

or $\left(s\cdot t\right)\left(x\right)=2x^2+12x+16$

---------

Similarly

$\left(s-t\right)\left(x\right)=s\left(x\right)-t\left(x\right)$

or $\left(s-t\right)\left(x\right)=\left(x+4\right)-\left(2x+4\right)=x+4-2x-4$

or $\left(s-t\right)\left(x\right)=-x$

---------

Similarly

$\left(s+t\right)\left(4\right)=s\left(4\right)+t\left(4\right)=\left(4+4\right)+\left(2\left(4\right)+4\right)=\left(8\right)+\left(12\right)=20$

$\left(s+t\right)\left(4\right)=20$

natulia [17]

Answer: 2.5%

Step-by-step explanation:

Let's use the rule of 3 here.

If the total price is $275,000 or 100% of the sale, then $6,875 is X% of the total sale.

Let's put money on one side and percentages on the other.

$\frac{275000}{6875}=\frac{100}{x}$

Solve for x;

$x=\frac{6875*100}{275000}$

$x=2.5$
