Answer:
x= 72
Step-by-step explanation:
combine the Xs on one side and then make the denominators the same and solve
8/12X +6 = 3/4X
sub 6 on both sides
then sub 3/4 (aka. 9/12)
-1/12X= -6
multiply by reciprocal (the fraction flip-flopped)(-12) on both sides
and you get 72
Answer:
Step-by-step explanation:
hello,
first of all we will study the quadratic expressions
we can write that, (the different answers provide good clues :-) )
and
so first of all as we cannot divide by 0 we need to take x different from 7, -12 and -30 and then we can write
hope this helps
Answer:
Step-by-step explanation:
Volume = 1/3(area of triangular base)height
To find the triangular base we would use heron formula Area = square root (s-a)(s-b)(s-c)
S = (a+b+c)/2 = 2.6 + 2.6 + 2.6 )/2
Find the Greatest Common Factor of both numbers which is 5. Then divide the numerator by 5 and the denominator by 5 and you will get 5/16 as the simplest form
300/5= 60
60x4(children)=240
240 seats will be for children and 60 seats for adults.
