Answer:
p -6= 11,
17 pairs
Step-by-step explanation:
Total pairs before giving away= p
Number of pairs given= 6
Pairs of shoes left= 11
Thus, the equation is p -6= 11.
To find the number of pairs they had initially, solve for p. This can be done by adding 6 on both sides to the equation above.
p= 11 +6
p= 17
Answer:
45 divided by 18 = 2.5
Step-by-step explanation
18+18=36 so that is 2 times but 45-36 =9 we can divide 9 by 18 and get a half.
2+0.5=2.5
Hope this helps!
Example:
y = 2x + 1 is a linear equation:
- When x increases, y increases twice as fast, so we need 2x
- When x is 0, y is already 1. So +1 is also needed
- And so: y = 2x + 1
Here are some example values:
x y = 2x + 1
-1 y = 2 × (-1) + 1 = -1
0 y = 2 × 0 + 1 = 1
1 y = 2 × 1 + 1 = 3
2 y = 2 × 2 + 1 = 5
-----------------------------------------------------------------------------
Each solution is a pair of numbers (x,y) that make the equation true. Solving a linear equation usually means finding the value of y for a given value of x. If the equation is already in the form y = mx + b, with x and y variables and m and b rational numbers, then the equation can be solved in algebraic terms.

Answer:
The inverse matrix is used to solve the system of linear equations. It also tells us the consistent or inconsistent behaviour of the solution of equations.
Step-by-step explanation:
In real life,
- Whereas in programming which is taught at the university, matrices and inverse matrices are used for coding and encrypting messages.
- Matrices are also used in representing the real world data's like the population of people, infant mortality rate, etc.
- They are best representation methods for plotting surveys.
First the number of ways of selecting 3 students out of 8 is 8*7*6/(3*2*1)=56.
There are 6 ways of arranging the officers, so the total number of ways is 6*56=336
