Answer:

5(4 + 3c) - 12 = 15c + 8

Step-by-step explanation:

1st step, expand it to make it a little easier to solve, 20 + 15c - 12

2nd step, subtract, 20 - 12 = 8

3rd step simplify, 15c + 8

The answer to the question is “8+15c” you multiply 5 and 4 and it equals to 20 and after that you subtract 20 and 12 which equal “8+15c”

5 ( c+ 2) = -20<br><br> 12a + 5 - 8a = -1<br><br> m - 3 - 6m = -27<br><br> please solve

mel-nik [20]

c = -6

a = -3/2

m = -24/5

Step-by-step explanation:

5(c + 2) = -20

5c + 10 = -20

5c = -20 - 10

5c = -30

<u>c = -6</u>

12a + 5 - 8a = -1

4a + 5 = -1

4a = -1 - 5

4a = -6

a = (-6)/4

<u>a = -3/2</u>

m - 3 - 6m = -27

-5m - 3 = -27 → (times -1)

5m + 3 = 27

5m = 27 - 3

5m = 24

<u>m = 24/5</u>

Consider the matrix shown below:

velikii [3]

Answer:

$A)\ \ \ \ \left[\begin{array}{ccc}8&-5\\-3&2\\\end{array}\right]$

Step-by-step explanation:

Given the matrix: $\left[\begin{array}{ccc}2&5\\3&8\\\end{array}\right]$ , it's inverse is calculated using the formula:

$\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]^{-1}=\frac{1}{det\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right] }\left[\begin{array}{ccc}d&-b\\-c&a\\\end{array}\right]$

#Therefore, we calculate as;

$\frac{1}{det\left[\begin{array}{ccc}2&5\\3&8\\\end{array}\right] }\left[\begin{array}{ccc}8&-5\\-3&2\\\end{array}\right] \\\\\\\\\#det\left[\begin{array}{ccc}2&5\\3&8\\\end{array}\right] =1\\\\\\\\=\frac{1}{1}\left[\begin{array}{ccc}8&-5\\-3&2\\\end{array}\right] \\\\\\\\=\left[\begin{array}{ccc}8&-5\\-3&2\\\end{array}\right]$

Hence, the inverse of the matrix is $\left[\begin{array}{ccc}8&-5\\-3&2\\\end{array}\right]$

Name the marked angle in 2 different ways.<br> W<br> T<br> V<br> U

Nezavi [6.7K]

The marked angle can be named in two different ways as: ∠HFG and ∠GFH.

<h3>How to Name an Angle?</h3>

To name an angle, the letter representing the vertex would always be at the middle.

Given the angle marked in the image below, where F is the vertex, we can name the marked angle in two different ways with F at the center as:

∠HFG and ∠GFH

Thus, the two different ways to name the marked angle are:

∠HFG and ∠GFH.
