If 12a - 5 = 4a + 11 ,then a= what?
FinnZ [79.3K]

Answer:

a=2

Step-by-step explanation:

12a - 5 = 4a + 11

Subtract 4a from each side

12a-4a - 5 = 4a-4a + 11

8a -5 = 11

Add 5 to each side

8a -5+5 = 11+5

8a = 16

8a/8 = 16/8

a =2

tia_tia [17]

Answer:

They saw <u>24</u> movies.

Step-by-step explanation:

The question is incomplete so the complete question is below:

A theater has a discount pass that cost nine dollars with the pass, admission is $6.50 per movie. Mike, Tyrell and Juanita all bought a pass and went to see movies together they spent a total of $183. Write and solve an equation to find out how many movies they saw.

Now, to find the number of movies they saw.

Let the number of movies they saw be x.

Discount pass = $9.

With the pass admission per movie is $6.50.

Total number of people = 3.

Total money spent = $183.

So, to get the number of movies they saw we write an equation:

3(9)+6.50(x)=183

Now, to solve the equation:

3(9)+6.50(x)=183

27+6.50x=183

<em>Subtracting on both sides by 27 we get:</em>

6.50x=156

<em>Dividing both sides by 6.50 we get:</em>

x=24.

Therefore, they saw 24 movies.

Question 6 of 10
Maksim231197 [3]

Answer:

(2.5 , 3.5)

Step-by-step explanation:

We can use the midpoint formula . Here the points are , (2,2) and (3,5) .

• <u>Using</u><u> </u><u>Midpo</u><u>int</u><u> Formula</u><u> </u><u>:</u><u>-</u><u> </u>

⇒ M = { (x1 + x2)/2 , (y1 + y2)/2 }

⇒ M = ( 2+3/2 , 5+2/2 )

⇒ M = ( 5/2 , 7/2 )

⇒ M = ( 2.5 , 3.5 )

<h3><u>Hence </u><u>the</u><u> </u><u>midpoint</u><u> </u><u>is</u><u> </u><u>(</u><u>2</u><u>.</u><u>5</u><u> </u><u>,</u><u> </u><u>3</u><u>.</u><u>5</u><u>)</u></h3>
