Answer:

$X = \begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}$

Step-by-step explanation:

$\begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix} +X = \begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}$

$X = \begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}-\begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix}$

$X = \begin{bmatrix} - 5-(-1) & - 1-(-2)\\ 2-4 & 1-8\end{bmatrix}$

$X = \begin{bmatrix} - 5+1 & - 1+2\\ 2-4 & 1-8\end{bmatrix}$

$X = \begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}$

Compare using <, >, or =. 7 2/5___ 7 3/8

katrin [286]

Answer:

Explanation:

Step 1 - Convert the mixed numbers into decimals

7 2/5

2/5 • 20/20 = 40/ 100

40/ 100 = 0.4

0.4 + 7.0 = 7.4

Therefore, 7 2/5 = 7.4

Step 2 - Convert the mixed numbers into decimals

7 3/8

3/ 8 = 0.375

0.375 + 7.0 = 7.375

Therefore, 7 3/8 = 7.375

Step 3 - Compare

7.4 < 7.375

So, 7 2/5 is less than 7 3/8

Twice the sum of a number and 5 is equal to three times the difference of the number and 2

Alexxx [7]

Answer:16

Step-by-step explanation:

Let the number be X

Twice the sum of a number and 5

= 2X+5

Three times the difference of the number and 2

= 3(X - 2)

Since Twice the sum of X and 5 is equal to three times the difference of the X and 2, This means

2(X + 5 )= 3(X - 2)

2X +10 = 3X - 6

3X -2X = 10 + 6 = 16

X = 16

Check

2×(16+5) =3×(16-2)

2×21 = 3×14

42 = 42

Highlight very briefly why/how when you subtract a negative number, that it yields a positive number. Will give brainliest

lbvjy [14]

When we build integers from natural numbers, we're looking for additive inverse of natural numbers?

What's an additive inverse? Well, for example, the additive inverse of 2 is a numbers $x$ such that

$2+x = 0$

We call this number -2. So, the real meaning behind the negative sign is "if you add me and my positive counterpart, the result is zero".

So, -5 is the additive inverse of 5, -16 is the additive inverse of 16, and so on, because

$5-5=0,\quad 16-16=0,\ldots$

Note that this is a symmetrical relation: if -5 is the inverse of 5, it is also true that 5 is the inverse of -5.

So, when you write something like

$5-(-4)$

it means that you want to add 5 and the inverse of the inverse of 4. But given what we just said, the inverse of the inverse of a number is the number itself, which is why subtracting a negative number is the same as adding it.
