Distance = Rate * Time Or, algebraically manipulated to our purpose..., and 1 and 2/3 miles changed to improper fraction..., (3 * 1 + 2)/3 = 5/3 miles ------ Rate = distance/time Rate =  5/3 miles divided by 50 minutes same as Rate = 5/3 miles * 1/50 minutes = 5/150 = 0.033 miles perRead more

I assume you mean STP. 6..5 g Zn (1 mole Zn/65.41 g)(1 mole H2/1 mole Zn) = 0.0994 moles H2 ------Now, PV = nRT (1.00 atmospheres)(X volume) = (0.0994 mole H2)(0.08206 L*atm/mol*K)(298.15 K) = 2.4 Liters volume H2 gas ======

A dictionary definition is "one of two or more numbers, algebraic expressions, or the like, that when multiplied together produce a given product." That is the definition of the noun. Factor can also be a verb, in which case it means "resolve into factors." For example, we can factor the expression 2x^2 … Read more

A multiplicative portion of a number. 2 and 4 are factors of 8 sqrt(8) can be factored thus sqrt(22 * 2 bringing out 2 from under the radical 2sqrt(2) Oddman would be the expert here. Perhaps he will see this and comment.

4 = 5/(X - 2) multiply through by the (X - 2) 4(X - 2) = 5 distribute 4X - 8 = 5 add 8 to each side 4X = 13 X = 13/4 ======check in original equation 4 = 5/(13/4 - 2) 2 = 8/4 ------ 4 = 5/(13/4 - 8/4) 4 = 5/(5/4) … Read more

Change to improper fractions. - 3 and 2/6 - (6*3+2)/6 = - 20/3 ------ 1 and 1/2 (2*1+1)/2 = 3/2 ------ - 20/6 divided by 3/2 same as - 20/6 * 2/3 - 40/18 reduces to - 20/9 ======( about - 2 and 1/5 ) I see you have a whole string of these easyRead more
