Answer:

Step-by-step explanation:

Remark

Read the following carefully.

There is a beautiful theorem that has to do with the endpoints of two angles sharing the same endpoints.  

To be a little clearer, I hope, that makes < BAC = <BDC because both angles have B and C as their endpoints inside the circle. Make sure you understand that statement before moving on.

For this problem <BDC = <CAB = 33 degrees.

That means that ADC = 37 + 33 = 70

Solution

<ADC and CBA are opposite angles.

That means that they add to 180

From the above statement in the Remark section <ADC = 37 + 33 = 70 degrees <ABD + <DBC = <ABC = m + 71

<ABC + ADC = 180

m + 71 + 70 = 180        Combine

m + 141 = 180               Subtract 141 from both sides.

m+141-141= 180 - 141    Combine

m = 39

Answer: m = 39

To solve the algebraic expression, add or subtract the variables with same power of variable.

The result of the given problem after simplifying is,

y=7m+n-6

<h3>How to write algebraic expression? </h3>

Algebraic expression are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used represent the general problem in the mathematical way to solve them.

To solve the algebraic expression, add or subtract the variables with same power of variable.

Given information-

The given numbers are,

Q=7m+3n\\R=11-2m\\S=n+5\\T=-3-3n

All the four number given in the form of unknown number m and n.

The result, need to be find is,

R-S+T+M

Let the result of above expression is y. Thus,

y=R-S+T+M

Put the values to solve it further,

y=(7m+3n)-(11-2m)+(n+5)+(-m-3n)

Solve it further by open the bracket as,

y=7m+3n-11+2m+n+5-m-3n\\y=7m+2m-m+3n+n-3n-11+5\\y=7m+n-6

Hence the result of the given problem after simplifying is,

y=7m+n-6
