System of Equations
Step-by-step explanation:
A system of equations refers to a number of equations with an equal number of variables. We will only look at the case of two linear equations in two unknowns. The bracket on the left indicates that the two equations are intended to be solved simultaneously, but it is not always used.
Answer: 88
Step-by-step explanation:
Given
The first row has 16 seats
then there are 3 more seats in each row
this follows an AP with the first term
and common difference ![d=3](https://tex.z-dn.net/?f=d%3D3)
So, no of seats in the 25 th row is
![\Rightarrow a_{25}=a+24d\\\Rightarrow a_{25}=16+3\times 24\\\Rightarrow a_{25}=88](https://tex.z-dn.net/?f=%5CRightarrow%20a_%7B25%7D%3Da%2B24d%5C%5C%5CRightarrow%20a_%7B25%7D%3D16%2B3%5Ctimes%2024%5C%5C%5CRightarrow%20a_%7B25%7D%3D88)
Thus, there are 88 seats in the 25 th row

Answer:
This is weirdly written, but let's try to solve it:
M is the mass of Molly
A is the mass of Arthur
G is the mass of Ginny.
We can represent the weight as:
(M + A) + G
or as:
A + (G + M)
the first situation shows that Molly and Arthur are weight together (this is why their weight is shown as only one), and then they weight Ginny alone.
The second situation shows that Arthur is weight alone, and Ginny and Molly are weight together (this is why their weight is written as only one)
