Multiply 7x23 = 161 to determine how many chairs there are in the theatre in total.
Subtract 8 from the total number of chairs to determine that 153 chairs remain after workers are finished.
Hope this helped

Answer:
4
Step-by-step explanation:
g(x)=0
Plug in 0
5*23(0) + 4
5*(0) + 4
0 + 4
= 4
Answer: A. Infinite number of solutions
Step-by-step explanation:
The given system of equations is expressed as
x + 3y = 5- - - - - - - - - - - - - -1
4x + 12y = 20- - - - - - - - - - - 2
We would apply the method of substitution. From equation 1, we would make x the subject by subtracting 3y from the left hand side and the right hand side of the equation. It becomes
x + 3y - 3y = 5 - 3y
x = 5 - 3y
Substituting x = 5 - 3y into equation 2, it becomes
4(5 - 3y) + 12y = 20
20 - 12y + 12y = 20
20 = 20
Therefore, the system of equations has an infinite number of solutions because as many values of x and y that satisfy the first equation, they would also satisfy the second equation.
