P = 7h
P = 5h + 50
These are the equations we have. Imagine they are lines on graph paper, and we have to find their intersection point (a point where an xy point is on both lines). To do this, we have to find the h and P. I'll use some algebra:
P - P = 5h + 50 - 7h
0 = -2h + 50
2h = 50
h = 25

There are 5 row and 8 tiles in each row calculated using two equation.
What are System of equation?
Simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.
Given I am an array made with 40 tiles I have an odd number of rows and an even number of tiles in each of my rows the number of my rows plus the number of tiles in each of my rows equals 13
Let "r" be the number of row and "t" be the number of tiles in each row.
Since, array has total 40 tiles
Thus,
r * t = 40
Also given
r +t = 13
From comparing these equation
r = 5 or 8
Since row is odd given
thus, r = 5
and t = 8
therefore, Two equations are used to determine the five rows and eight tiles in each row.

Answer:
Choosing ten students from a box that contains the names of the entire group
Step-by-step explanation:
If each and every unit has equal chance of being selected in a sample then it is called Random Sampling. Here choice of sample should be unbiased and independent.
Option (a) is incorrect because here selection of student is not independent as only those students are choosing who also participate in music class.
Option (b) is correct option as selection of students are independent and unbiased. Also here each student has equal chance of being selected in sample.
Option (c) can't be chosen as selection of student is done from particular cluster.
Option (d) is also incorrect as here we put condition of male and female students.
This is the only one where everyone has an equal chance of being chosen.
b. False
