Answer:

5.33 or 5 $\frac{1}{3}$

Step-by-step explanation:

Assuming you don't want the answer in decimals, this is the process to find the answer in fractions:

1 $\frac{2}{5}$ + (3 $\frac{1}{3}$ + $\frac{3}{5}$ )

= $\frac{7}{5}$ + $\frac{10}{3}$ + $\frac{3}{5}$ → convert into mixed fractions

= $\frac{21}{15}$ + $\frac{50}{15}$ + $\frac{9}{15}$ → find the least common denominator to make them the same

= $\frac{80}{15}$ = 5 $\frac{5}{15}$ = 5 $\frac{1}{3}$ → = add and simplify

The elements of Matrix C are shown below.

sergeinik [125]

The matrix that represents the matrix D is $\left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

<h3>How to determine the matrix d?</h3>

Given the elements of the matrix C.

The matrix c is represented by its rows and columns element, and the arrangements are:

C11 = 3 C12 = 1 C13=-9 C14 = 8

C21 = 2 C22=2 C23 =0 C24 = 5

C31 = 16 C32 = 1 C33=-3 C34=11

Remove the matrix name and position

3 1 9 8

2 2 0 5

16 1 -3 11

Represent properly as a matrix:

$C = \left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

Matrix C equals matrix D.

So, we have:

$D = \left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

Hence, the matrix that represents matrix D is $\left[\begin{array}{cccc}3&1&-9&8\\2&2&0&5\\16&1&-3&11\end{array}\right]$

Algebra I

Terms/Coefficients
Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 2x + 1

x + 3y = 10

Step 2: Solve for x

Substitution

Substitute in y: x + 3(2x + 1) = 10
Distribute 3: x + 6x + 3 = 10
Combine like terms: 7x + 3 = 10
[Subtraction Property of Equality] Subtract 3 on both sides: 7x = 7
[Division Property of Equality] Divide 7 on both sides: x = 1

Step 3: Solve for y

Define original equation: y = 2x + 1
Substitute in x: y = 2(1) + 1
Multiply: y = 2 + 1
Add: y = 3

Step 4: Find difference

y = 3

x = 1

Subtract: 3 - 1 = 2
