Answer:
10. First you multiply both sides by 3, making it 2x + 5 = 24
Then you subtract 5 from both sides making it 2x = 19
You dive both sides by 2 making x = 9.5
The answer is x = 9.5
11. First you need to find how much you need to pay each year. 12,000 x 0.05
you can make it easier by changing it to 120 x 5 = 600
You need to pay that for three years so 600 x 3 = 1800
Plus you need to pay the original money. 12,000 + 1,800 = 13,800
The answer is $13,800
12. First you change kilometers into centimeters. 172 km is 172,000 meters. 172,000 meters is 17,200,000
Then, you need to do 17,200,000 ÷ 500,000 but you can make it simple and do 172 ÷ 5 = 34.4
The answer is 34.4 cm

Explanation:</h2>
Here we have the following points:
<h3>3) </h3>
Here we need to reflect each point over the x-axis and write the coordinates of the new points. So:
<h3>4)</h3>
The x coordinate of each point remains the same while the y coordinate of each point is multiplied by -1. In other words, when reflecting any point over the x-axis we follow this rule:
<h3>5)</h3>
The difference is that the pre-image and the reflected point will have the same x-coordinates but different y-coordinates. So the x-axis will work as a mirror.
