−6.5(n−5)=18.2
distribute
-6.5n +32.5 = 18.2
subtract 32.5 from each side
-6.5n = -13.4
divide each side by -6.5
n=2.2
Answer n=2.2
Use the equation:
10x + 23 = 100
Subtract 23 from each side:
10x = 77
EVENLY divide by 10, leaving a remainder:
x = 7 charities and $7 left over
Hope this helps!! :)
Answer: 16
Step-by-step explanation: 16 would be the only perfect square that is between 10 and 20. A perfect square means that a whole number multiplied by itself will give us 16. In this case, if we multiply 4 × 4 we get a product of 16 so 16 would be classified as a perfect square.
The product of the matrices is an identity matrix. Then Both the matrices are multiplicative inverse to each other.
<h3>What is the matrix?</h3>
A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The a_{ij} element in a matrix, such as M, refers to the i-th row and j-th column element.
The matrices are given below.
Then show that both the matrices are multiplicative inverse to each other.
If the product of the matrices is an identity matrix then the matrices are multiplicative inverse to each other.
Then we have
Then both the matrices are multiplicative inverse to each other.
