<span><u><em>Answer:</em></u>
The number is -10.4
<u><em>Explanation:</em></u>
Assume that the number we are looking for is x.
Now, we want to get 10 times te sum of half the number and 6 and equate this expression to 8. Then we can solve for x
<u>Let's take this step by step:</u>
half the number is 0.5x
the sum of half the number and 6 is 0.5x + 6
10 times the sum of half the number and 6 is 10(0.5x +6)
10 times the sum of half the number and 6 equals 8 is 10(0.5x+6) = 8
<u>Now we can solve for x as follows:</u>
10(0.5x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = -52
x = -52/5
x = -10.4

Step-by-step explanation:
90° clockwise rotation makes the transformation ...
(x, y) ⇒ (y, -x)
Your points are transformed to ...
- (-5, -1) ⇒ (-1, 5)
- (-3, -2) ⇒ (-2, 3)
- (-3, 2) ⇒ (2, 3)
