Answer/Step-by-step explanation:

11/2z+9/5=1.8+12z-6.5z

We move all terms to the left:

11/2z+9/5-(1.8+12z-6.5z)=0

Domain of the equation: 2z!=0

z!=0/2

z!=0

z∈R

We add all the numbers together, and all the variables

11/2z-(5.5z+1.8)+9/5=0

We get rid of parentheses

11/2z-5.5z-1.8+9/5=0

We calculate fractions

<u>There is no solution for this equation</u>

Citrus2011 [14]
Okay. Basically, a is greater than or equal to 9.
First, you do distribute the 2.
8a+2-10a(< or =)20
Subtract two on both sides.
8a-10a(< or =)18
Then subtract 10a from 8a
-2a(< or =)18
Divide by two on both sides
and switch around the greater than sign since you divided by a <span>-2
</span>a(> or =)-9
<span>And if you check, -9 works, -8 works, and -10 doesn't work.</span>

Answer:

A

=  \frac{78}{360}  \\  =  \frac{13}{60}

B

let \: total \: number \: be \: x \\  \frac{13}{60} x = 1164 \\ x =  \frac{1164 \times 60}{13}  \\ x = 5372 \: movies

C

A year has (4 × 12) weeks

= 48 weeks.

In 1 week = 9,568,000 movies

48 weeks = (48 × 9,568,000) movies

Average movies = 459.264 movies

D

<em>Since</em><em> </em><em>9</em><em>.</em><em>5</em><em>6</em><em>8</em><em> </em><em>million</em><em> </em><em>movies</em><em> </em><em>are</em><em> </em><em>rented</em><em>.</em>

<em>How</em><em> </em><em>about</em><em> </em><em>in</em><em> </em><em>one</em><em> </em><em>year</em><em> </em><em>(</em><em> </em><em>4</em><em>8</em><em> </em><em>weeks</em><em> </em><em>)</em>

<em>Convert</em><em> </em><em>1</em><em> </em><em>year</em><em> </em><em>to</em><em> </em><em>weeks</em><em> </em><em>and</em><em> </em><em>compare</em><em> </em><em>with</em><em> </em><em>1</em><em> </em><em>week</em>
