What is 7 1/4 - 4 11/12?

Mathematics

yaroslaw [1]3 years ago

The answer would be:
Convert 7 1/4 to 7 3/12,
then, 7-4 = 3,
3/12-11/12 = -8/12, then, 
3 - 8/12, which would equal 
2 4/12, which simplifies to 2 1/3.

Hope this helps and have a nice day:)

Georgia [21]
(a) |AB| = |A| |B| = -1 * 2 = -2. 

<span>(b) |B^5| = |B|^5 = 2^5 = 32. </span>

<span>(c) Since A is 4 x 4, </span>
<span>|2A| = 2^4 * |A| = 16 * -1 = -16. </span>

<span>(d) Since determinants are invariant under transposition, </span>
<span>|A^t A| = |A^t| |A| = |A| |A| = (-1)(-1) = 1. </span>

<span>(e) |B^(-1) AB| = |B^(-1)| |A| |B| </span>
<span>.....................= (1/|B|) |A| |B| </span>

Answer:

Hi dear, let's solve it

Step-by-step explanation:

step A: x + (3x-1) + 5x = 180

➡️ x+3x-1+5x=180➡️9x-1=180

9x=180+1➡️9x=181➡️x=181÷9➡️x≈20.1

A angle: 20.1

B angle: 59.3

C angle: 100.5
