9 x 65/9 = 65
65 x 10 = 650 then 650 - 65 = 585
5 5 x 9 = 45; 5 x 13 = 65 The greatest common factor of 65 and 45 is 5.
That equation can not be factored. It can however be solved for x: x2 - 9x + 4 = 0 x2 - 9x + 81/4 = 81/4 - 4 (x - 9/2)2 = 81/4 - 16/4 (x - 9/2)2 = 65/4 x - 9/2 = ± √65 / 2 x = (9 ± √65) / 2
Conversion: -65°C → -65 × 9/5 + 32 °F = -85°F
8 x 9 - 7 = 65
-65 °F is equal to about -53.9°C The conversion formula is Celsius temperature = 5/9 x (Fahrenheit temperature - 32) 5/9[(-65) - 32] = 5/9 (-97) = 53.888
to find percent, the equation used is p/100 = is/of in this case, it would be 9/100= x/65 (cross multiply to get 585=100x) Divide both sides by 100 to get x= 5.85
9 -56 = -47
64 is a square number (8 x 8). The next square number is 81 (9 x 9) The ones in between are not square.
65 = 1 x 65, 5 x 13
