sqrt(3h) = 1/3
square both sides
3h = 1/9
h = 1/27
==========check in original equation
sqrt[(3 * 1/27) = 1/3
sqrt(1/9) = 1/3
1/3 = 1/3
=============checks ( when in doubt square both sides! )
3h+13 = 7 3h = 7-13 3h = -6 h = -2
8h - 10h = 3h + 25-2h = 3h + 25-5h = 25-h = 5h = -5
5h - 3h + 9h = 176 11h = 176 h = 16
6h 8min
-9h-6+12h+40 = 22 3h+34 = 22 3h = 22-34 3h = -12 h = -4
h = -5 8h - 10h = 3h + 25 -2h = 3h + 25 -2h - 3h = 3h - 3h + 25 -5h = 25 h = -5 CHECK: 8(-5) - 10(-5) = 3(-5) + 25 -40 - -50 = -15 + 25 -40 + 50 = 10 10 = 10 CORRECT
h=16
3h-5h + 11 = 17 is ------2h + 11 = 17- 11 -11____________-2h = 6___ ___-2 -2h = -3 (This is the answer.)
simplify both sides of the equation: 1/3h+(-4)(2/3h)+(-4)(-3)=2/3h+-6 ~ distribute that 1/3h+-8/3h+12=2/3h+-6 (1/3h+-8/3h)+(12)=2/3h-6 ~ combine like terms for this -7/3h+12=2/3h-6 -7/3h+12=2/3h-6 subtract 2/3h from both sides: -7/3h+12-_2/3h=_2/3h-6-2/3h -3h+12=6 subtract 12 from both sides: -3h+12-12=-6-12 -3h=-18 divide both sides by -3 -3h/-3=-18/-3 h=6
To simplify the expression (3h - 2(1 + 4h)), first distribute the (-2) across the terms in the parentheses: [ 3h - 2 - 8h. ] Next, combine the like terms (3h) and (-8h): [ (3h - 8h) - 2 = -5h - 2. ] Thus, the expression in standard form is (-5h - 2).
3h + (2h 20m) + 35m = (3+2)h + (20+35)m = 5h + 55m
An equations doesn't have a rate of change, but this equation tells you that ' C ' changes 3 times as fast as ' h ' does.
