Hope this helps :)
Think of it like this:
of = multiplication of the equation
is= equals
and whatever you are looking for is your variable
so....
.40 times X = 56
Answer:
<h3>The solution of the given equation is x = 105 °∈ ( 0 , 2pi)</h3>
Step-by-step explanation:
Step(i):-
Given equation is sin x cos x = -1/4
we know that trigonometry formula
2 sin x cos x = sin 2x
2 ( sin 2 x) = -1
sin2x = -1/2
Step(ii):-
sin2x = 
<h2> sin2x = sin 210</h2><h2> 2x = 7π/6</h2><h2> 2x = 210°</h2><h3> x = 105 °</h3><h3>The solution of the given equation is x = 105 °∈ ( 0 , 2pi)</h3>
1/5(3x - 0.5) + 1/6= x/5 + 0.5
change decimals to fractions (0.5=1/2)
1/5(3x - 1/2) + 1/6= x/5 + 1/2
multiply 1/5 by each term in parentheses
(1/5*3x) + (1/5*-1/2) + 1/6= x/5 + 1/2
multiply within parentheses
3x/5 - 1/10 + 1/6= x/5 + 1/2
need a common denominator; all denominators go into 30
18x/30 - 3/30 + 5/30= 6x/30 + 15/30
combine like terms
18x/30 + 2/30= 6x/30 + 15/30
subtract 6x/30 from both sides
12x/30 + 2/30= 15/30
subtract 2/30 from both sides
12x/30= 13/30
multiply both sides by 30 to eliminate fractions
(12x/30)(30)= (13/30)(30)
12x= 13
divide both sides by 12
x= 13/12 or 1.083333
ANSWER: x= 13/12 or 1.083333
