Plz! I need this to be answered! Solve − 3/8 c ≥ 9
ExtremeBDS [4]

-\dfrac{3}{8}c \geq 9

First we need to multiply all the inequality by 8 to get rid of the denominator

-\dfrac{3}{8}c \geq 9|\times 8\\-3c\geq 72

Now we need to divide all inequality by -3

-3c\geq 72|\div(-3)

When dividing or multiplying an inequality by a negative number the inequality sign changes, so

c\leq -24

Answer: c ≤ -24

\log_2 (\log_5( \log_3x)) = 0\\
D:x>0 \wedge \log_3x>0 \wedge \log_5(\log_3x)>0\\
D:x>0\wedge x>1 \wedge\log_3x>1\\
D:x>1 \wedge x>3\\
D:x>3\\
\log_5(\log_3x)=1\\
\log_3x=5\\
x=3^5\\
x=243

A rectangular parking lot at the megamall is 7/10 mile long and 1/4 mile wide. How much fencing is needed to enclose the lot?
iris [78.8K]
Greetings!

"<span>A rectangular parking lot at the mega-mall is 7/10 mile long and 1/4 mile wide. How much fencing is needed to enclose the lot?"...

This question is essentially asking to solve for the perimeter. The formula for the perimeter of a rectangle is: 
</span>2(l+w)

Input the information we already know:
2(7/10+1/4)
Find A common denominator.
2(14/20+5/20)
Simplify.
2(19/20)
2/1(19/20)
38/20
Reduce to Lowest Terms.
=19/10
or
=1 9/10

1 9/10 miles of fencing will be required to enclose the entire lot.

Hope this helps.
