Answer:
Step-by-step explanation:
Alright, lets get started.

These are mixed number given.
Suppose the complete mixed number of second place is x.
Converting mixed numbers into fractions.

Adding x in both sides


Making common denominator



In mixed number form:

So comparing with given equation, the '?' sign will be equal to 4.
Hence the answer is 4 : Answer
Hope it will help :)
Answer:
18
Step-by-step explanation:
7b-2+3b+2=180
10b=180
b=18
Answer:
The answer is a unique triangle.
Step-by-step explanation:
9+7=16, 16 is less than 18.
If two sides are added up and equal or are less than the third side, they are a unique triangle.
General form of a linear equation is ax+by+c=0 where a,b, and c are three real numbers.
So, we can shift all the terms in one side of the equation. Hence, first step is to remove y from the left side. So, subtract y from each sides.
y-y=3x+2-y
0= 3x - y +2 (By simplifying)
So, the general form of the given equation is 3x-y+2=0.
