Answer:
the second one
Step-by-step explanation:
For this case we have the following equation:

We apply distributive property on the left side of the equation, taking into account that:

So:

Subtracting 3m from both sides of the equation:

Equal signs are added and the same sign is placed:

We subtract 6 from both sides of the equation:

We divide between -4 to both sides of the equation:

Thus, the solution of the equation is
ANswer:

Answer:
sin (55) = DE / AD
AD = DE / sin (55)
AD = 8 / sin (55)
And
tan (55) = DC / AD
tan (55) = DC / [8 / sin (55) ]
DC = 8 tan (55) / sin (55)
AD * DC =
[8 /sin (55) ] [ 8 tan (55) / sin (55) ] = 136 units^2

Answer:
Equation: 65+1.50m=78.50
Solution to the equation= 9 minutes
Step-by-step explanation:
The parents have to give 65 dollars for their children to be under care till 6 o'clock. AFter 6 o'clock, they had to pay 1.50 dollars for one minute. This parent gives a total of 78.50 dollar for that day. So, the equation is :
65+1.50m=78.50
(btw, m stands for minutes)
So to solve the equation:
1.50m=13.50
m= 9
