Solving inequalities by multiplication and division 1. -8 < 8w

Answer:

w > -1

Step-by-step explanation:

Hello There!

We want to simplify this expression to be more specific we want to isolate the variable (w) using inverse operations

So we want to get rid of the 8 in 8w

8w is the same as 8 times w (multiplication)

The inverse of multiplication is division so to get rid of the 8 we want to divide by 8 but remember whatever we do to one side we want to do to the other side. So we divide each side by 8

-8/8 = - 1

8w/8=w

we're left with w > -1

\huge\text{Hey there!}

\mathsf{-8 < 8w}

\large\text{TURN/FLIP the  given EQUATION  around}

\mathsf{8w > -8}

\large\text{DIVIDE 8 to BOTH SIDES}

\mathsf{\dfrac{8w}{8}>\dfrac{-8}{8}}

\large\text{Cancel out: }\mathsf{\dfrac{8}{8}}\large\text{ because that gives you 1}

\large\text{Keep: } \mathsf{\dfrac{-8}{8}}\large\text{ because that helps you  compare  to  the  w-value}

\large\text{New equation: } \mathsf{w>\dfrac{-8}{8}}

\mathsf{\dfrac{-8}{8}=\bf -1}

\mathsf{w>-1}

\mathsf{It\ is\ an\ O P E N\ circle\  shaded\  to\ the\RIGHT\, starting\ at\ the\  -1}

\boxed{\boxed{\large\text{Therefore, your \underline{answer} is: }\mathsf{\bf w > -1}}}\huge\checkmark

\text{Good luck on your assignment and enjoy your day!}

The area of a rectangular raised garden bed for growing beets is given by the expression(3b)(3b-3). The length, l, of the mat is
mars1129 [50]

Answer:

C and D

Step-by-step explanation:

The area of a rectangular raised garden bed for growing beets is given by the expression (3b)(3b-3).

The area of the rectangle is

A=\text{Width}\cdot \text{Length}

Thus,

\text{Width}=3b\\ \\\text{Length}=3b-3

or

\text{Width}=3b-3\\ \\\text{Length}=3b

The length of the mat is greater than its width. Since

3b>3b-3

then

\text{Width}=3b-3\\ \\\text{Length}=3b

Options A and B are false, options C and D are true.
