How to solve this please? <br><br> 2x - 5 = 4
Nutka1998 [239]
Hey there, below you will find the work and answer to your question.

2x-5=4

First lets get the 2x by itself so we have to add 5 on both sides.
2x-5=4
   +5 +5
2x=9
Now we need to get the X by itself so divide each side by 2
\frac{2x}{2} =  \frac{9}{2}
Now we are left with the following
X=\frac{9}{2}
We must simplfy the fraction
2 will go into 9 four times with 1 left over. So the mixed fraction answer would be:
x=4 \frac{1}{2}
As a decimal you would just divide 9 and 2
x=4.5

Hope this helped!

If a person walks 2.4 miles in 1.5 hours how far can you walk in three hours
Mars2501 [29]
As three hours divided by 2 is 1.5 hours, we know that to find how far the person walks in hours, we simply have to double the distance the person walked in 1.5 hours.

2.4*2=4.8

The person walked 4.8 miles in three hours.

Does that make sense?

a hockey season ticket holder pays $99.26 for her tickets plus $4.50 for a program each game. A second person pays $18.68 for a
blsea [12.9K]

Answer:

7 games

Step-by-step explanation:

<u>First Person:</u>

Fixed Cost of 99.26

Variable Cost of 4.50 per game (program cost)

<u>Second Person:</u>

No Fixed Cost

Variable cost of 18.68 per game (ticket cost)

Now, we let the number of games be "x", so we can write 2 equations for each person. Then we equate and find at what number of games, the amount paid by both person would be same. Shown below:

<u>First Person Equation:</u>

99.26 + 4.50x

<u>Second Person Equation:</u>

18.68x

Now, equate and solve for x:

99.26 + 4.50x = 18.68x

99.26 = 18.68x - 4.50x

99.26 = 14.18x

x = 99.26/14.18

x = 7

So, the answer is 7 games
