You need to find the common denominator first. 3 * 4 = 12
3/4 = 9/12 and 1/3 = 4/12
9/12 - 4/12 = 5/12
The equation used for this is

=
if you knew n then we could solve this equation
Answer:
no triangles
Step-by-step explanation:
As we know the basic rule to form a triangle is that the sum of the two sides must be greater than the third one.
Given that:
4 m, 5.1 m, 12.5 m
We have: 4 m + 5.1 m = 9.1 m < 12.5 m
So no triangles can be formed.
Answer:
x = 0
Step-by-step explanation:
-7(5-3x)=-35
Divide by -7
-7/-7(5-3x)=-35/-7
5 -3x = 5
Subtract 5 from each side
5-3x-5 = 5-5
-3x=0
Divide by -3
x=0
The answer is 18.8
Just divide 94/5
