Answer:
For A the answer is 18. B is 24. And C is 45
To solve this problem, the first thing we have to do is regroup the terms so that we can then subtract, simplify, subtract, and finally simplify again.
But first we must know.
<h3>¿What are the equations?</h3>
Equations are those mathematical equalities divided between two expressions which are called members and separated by their equal sign, in which known elements and unknown or unknown data appear, related by mathematical operations.
<h3>We solve the problem:</h3>
- 8n - 7 = -12 + 3n
- 8n - 7 = 3n - 12
- 8n - 7 - 3n = -12
- 5n - 7 = -12
- 5n = -12 + 7
- 5n = -5
- N = -1
Now we must check our results.
8n -7 = -12 + 3n
8 × - 1 - 7 = -12 + 3 × - 1
- 8 - 7 = - 12 - 3
- 15 = - 12 - 3
- 15 = - 15
So, our results are correct, the answer is n = - 1
¡Hope this helped!
8 x 3 = 24
24 + 4 = 28
Now if 10 purses are made in 8 hours, and we can see we timesed 8, 3 times, thats 10 x 3 = 30
Now we take in to count the last 4 hours
30 + 4 = 34
And 4 is half of 8 so if we cut 10 in half we get 5.
So, the answer is 35
At least that's what I got :)
<span>P (0, 0) across x = -3 will change the x value. From 0 to -3 which is 3 units down, so the reflection will be another 3 units down ( points are the same distance from the reflection line) so the new x-value is -6 now just do the same thing for the y-value and you will get an image of P¹ ( -6, -6 ) </span>
