Answer:
In the given expression 
Variables = m, r
Coefficients = 7, 6 and -3
constant= -8
Step-by-step explanation:
We are given the expression 
We need to give variable, coefficients and constant.
Variable: The value of variable may change. It can be represented by x, y or any other letter
Coefficients: A numerical or constant quality that is placed with the variable. For example in 4x, 4 is coefficient
Constant: It is fixed value. It cannot be changed.
So, in the given expression 
Variables = m, r
Coefficients = 7, 6 and -3
constant= -8

Answer:100. Step-by-step explanation round to to nearest 10
So,1 3/4 x 2 = 1 6/8
1 6/8 + 2 3/8 = 4 1/8
And now 4 1/8 + 5 7/8 = 10
