1 answer:

5 0

27-2b > -6
-2b > -6-27
-2b > -33
b < -33/-2 (you have to change the sign when you divide with a negative number)
b < 16.5
(all the signs are supposed to have a line under them to make them greater or equal or less than or equal to)

-x - 9 $\geq 5$

You want to get x by itself.

First subtract 9 from both sides of the equation.

-x - 9 $\geq 5$
+9 +9

-x $\geq 14$

Then divide -1 on both sides.

-x/-1 $\geq 14/-1$

I'm pretty sure when you divide a negative number when solving inequalities, you switch the sign.

x $\leq 5$

The original price of a pair of shoes is $42. The sale price is 20% off the original price. What is the amount off the original

GREYUIT [131]

Answer:

a) What is the amount off the original price?

= $8.4

b) What is the new price for the pair of shoes?

= $33.6

Step-by-step explanation:

a) What is the amount off the original price?

We are told that:

The sale price is 20% off the original price.

Original price = $42

Hence:

$42 × 20%

$42 × 20/100

= $8.4

b) What is the new price for the pair of shoes?

The new price =

0riginal price - Amount off the original price

= $42 - $8.4

= $33.6

The original price = $33.6
