Answer=303.6
When rounding numbers to the nearest tenth, we need to look to the number in the hundredths place.
303.55
If the number is 5 or greater, we round up. If the number is 4 or less, we round down. The number IS 5, so we round up.
303.55 becomes 303.6
A. C= 0.1d + 30
because if u take the point (100,40), then d= 100 and c=40. Now 0.1d means = 10 and 10 + 30 gives 40 which is equal to C.
-5x = x + 6(1-x)
-5x = x + 6(1) + 6(-x)
-5x = x + 6 -6x
-5x = x - 6x + 6
-5x = -5x + 6
-5x + 5x = 6
0 = 6 Not equal. No solution.
(2x-5)² = (2x-1)(2x+1) -10(2x-1)
(2x-5)(2x-5) = (2x-1)(2x+1) - 20x + 10
2x(2x-5)-5(2x-5) = 2x(2x+1)-1(2x+1) - 20x + 10
4x² - 10x -10x + 25 = 4x² + 2x - 2x -1 - 20x + 10
4x² - 20x + 25 = 4x² - 20x - 1 + 10
4x² - 20x + 25 = 4x² - 20x - 9
Not equal. No solution.
