6x + ( 3x - 9) = 90°( being complementary angles )
6x+3x -9 = 90°
9x = 90° + 9
x = 99 / 9
x = 11
Number 9 is 15 and number 10 is 30. There was 9 rectangles on number 9. 45 divided by 9 is 5, so each rectangle is worth 5. 3x5=15.
$10 for one roller. If it was $30 for 2 cans of paint and one roller, and $50 for 3 cans of paint and 2 rollers, just make everything $10.

Answer:
Step-by-step explanation:
x/3.4=23/43
