Answer:
8/12
Step-by-step explanation:
if the denominator 3 needs to get to 12 multiply it by 4
and the rule is do the same to both the numerator and denomenator so 4 x 2 is 8 making it 8/12

Answer:
x = 4
Step-by-step explanation:
4x + 2 = 5x -6
4x -5x = 6-2
-x = 4
x = 4
Answer:
8
Step-by-step explanation:
8a-(2b+3c)
a=3
b=5
c=2
You plug in the numbers:
8(3) - (2(5)+3(2))
multiply inside the parenthesis first
24-(10+6)
24-16 = 8
You know the area, so you can use the area formula A = 1/2(a+b) (a and b being the parallel sides AB and CD)
So, set 32.5 = 1/2 (AB +CD)
substitute --> 32.5 = 1/2( x+(x+1) )
simplify --> 32.5 = (2x+1)/2
simplify again --> 65 = 2x +1 --> 64 =2x --> 32 =x
Now that you have x, you can substitute it into the formula for your height (x-1) to get 31
c = 5j
c + j = 18
5j + j = 18
6j = 18
j = 3
c = 5(3) = 15
