Answer:
Length of hypotenuse of given triangle
= sqrt(356)   (exact value)
= 18.87 (to 2 decimal places)
Step-by-step explanation:
Using the pythagorean Theorem,
The hypotenuse 
c = sqrt(a^2+b^2)
= sqrt(16^2+10^2)
= sqrt(356)   (exact value)
= 18.87 (to 2 decimal places)
 
        
                    
             
        
        
        
36 teaspoons. since the number of quarts is multiplied by 3, multiply the number of teaspoons as well. 12 × 3 = 36
 
        
             
        
        
        




First, write both the equations in its standard form.

Now, write the equations in form of matrix.

Then, multiply the equation towards the left by using the inverse of matrix 

The product of the matrix & its inverse will be the identity matrix.

Now, multiply the matrices that lie on the left-hand side of the equal sign.

For the 2 × 2 matrix  , the inverse matrix is ⇨
, the inverse matrix is ⇨  .
.

Do the calculations.

Multiply the matrices.

Do the arithmetics again.

Finally, extract the matrix elements x & y & write them separately.

 
        
                    
             
        
        
        
8.545 rounded to the nearest tenth is 8.5. I hope this helps.
