So when you work with variables (x, y or any other letter), when they're beside a number it usually means to multiply.
So 3y can also be written as 3(3). So 3 multiplied by 3 is equal to 9
So now our problem looks like this,
x/9.
Since we already know what x is equal to, our problem will look like this
18/9.
So now all we have to do is divide.
18 divided by 9 is 2
So therefore, your answer is 2.
I hope this helps :)
Answer:
2 by 2
Step-by-step explanation:
The first matrix is 2 x 3; that is, it has 2 rows and 3 columns.
The second matrix is 3 x 2.
Following rules of matrix multiplication,
a 2 by 3 matrix multiplying a 3 by 2 matrix results in a product with the dimensions 2 by 2.
The constant of proportionality is x=y/5 because its the constant that is not changing in he proportion. It represents the total of members made for washing x cars.
