Answer:

\huge\boxed{t=3}

Step-by-step explanation:

-5(t+3)=-30

<h3>METHOD 1:</h3>

-5(t+3)=-30    <em>divide both sides by (-5)</em>

<em />\dfrac{-5\!\!\!\!\diagup(t+3)}{-5\!\!\!\!\diagup}=\dfrac{-30}{-5}<em />

<em />t+3=6<em>       subtract 3 from both sides</em>

t+3-3=6-3\\t=3

<h3>METHOD 2:</h3>

-5(t+3)=-30       <em>use the distributive property </em><em>a(b + c) = ab + ac</em>

<em />(-5)(t)+(-5)(3)=-30<em />

<em />-5t-15=-30<em>     </em><em>add 15 to both sides</em>

<em />-5t-15+15=-30+15<em />

<em />-5t=-15<em>         divide both sides by (-5)</em>

\dfrac{-5t}{-5}=\dfrac{-15}{-5}\\\\t=3

Which could be the area of one face of the rectangular prism? Select three options.
antiseptic1488 [7]

Answer:

44cm^2

Step-by-step explanation:

We work with area for rectangles using the face of the longer length first as this is the awkward length the perpendicular side to the easy calculation of the square and sits perpendicular to the square.

We choose the longer length and plug in and choose one of the two calculation answers.

11 x 4 = 44

11 x 6 = 66

We see the answer is 44cm^2, so we choose this one.

At the movie theatre, child admission is $5.10 and adult admission is $9.00 .
sveticcg [70]

Answer:

5.10 X +9.00 Y = 831.60

We also know that for Wedneday we have two times tickets for adults compared to child so we have

Y =2x

And using this condition we have:

5.10 X + 18 X = 831.60

And solving for X we got:

X= \frac{831.60}{23.1}=36

So then the number of tickets sold for child are 36

Step-by-step explanation:

For this problem we can set upt the following notation

X = number of tickets for child

Y= number of tickets for adults

And we know that the total revenue  for Wednesday was 831.60. So then we can set up the following equation for the total revenue

5.10 X +9.00 Y = 831.60

We also know that for Wedneday we have two times tickets for adults compared to child so we have

Y =2x

And using this condition we have:

5.10 X + 18 X = 831.60

And solving for X we got:

X= \frac{831.60}{23.1}=36

So then the number of tickets sold for child are 36
