6 - a = 1/3(9a - 18)
6 - a = 3a - 6
-a - 3a = -6 - 6
-4a = -12
a = -12/-4
a = 3..........one solution
Two of the side lengths and one of the angles of both of the triangles. Hope this helps!
Its a simple equatioon,
First write the information that is given to you (as an equation) 14+x=17
Since you have a variable that is "x" you need to take it out of the equation as x=17-14 and put the 17 (that is the result) and then since you're adding 14, at the other side you'll substract it, finally do the opperation and you get your result that is x=3
It says that Monday is 'below zero', so Monday is negative
Wednesday is neither positive or negative, so it is zero
Monday is opposite of Tuesday, so if Monday is negative, Tuesday is positive
your order from positive to negative
Tuesday, Wednesday, Monday
hope this helps
