Answer:

x<−7

Step-by-step explanation:

This is an inequality, so you treat as a equation, but when you multiply or divide by a negative number, you flip the inequality.

1. Use distributive property

-x+2<-3x-12

2. Add 3x to both sides.

2x+2<−12

3. -2 from both sides

2x<−14

4. Divide by 2

x<−7

If the area of a rectangle 16s2t and the length is 8st2, what would the width of the rectangle, given that width is found by div

Dafna1 [17]

Area = Length x Width
Substituting the given values:
16S^2 t = 8St^2 x Width
Manipulating for Width:
Width = 16S^2 t / 8St^2
Rewriting the squared terms in simplified form :
Width = 16 x S x S x t / 8 x S x t x t
Cancelling the like terms
Width = 16 x S / 8 x t
Cancelling the numeric terms :

Width = 2S / t
