Answer:

4. m_LON + m_MON = m_LON; m_JKL + m_IKH = m_HKJ

Step-by-step explanation:

Both interior angles of each add up to m_LON:m_HKJ

To prove this we show the interior angles add + sign to each prove LON angle, and : colon separates from the proof of m_JKL+m_IKH= m_HKJ.

Simplify |-3| + 6 ÷ (4 - 1) · 8. 8 13 19 24

Dima020 [189]

Answer:

Step-by-step explanation:

The equation has "absolute value" , "addition", "subtraction", "division", and "multiplication", and "parenthesis".

The order we follow here would be:

PEMDAS, which is "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction"

Also, note, we can do absolute value first, before these.

Now let's simplify using PEMDAS:

$|-3|+6/(4-1)*8\\=3+6/(4-1)*8\\=3+6/3*8\\=3+2*8\\=3+16\\=19$

So the answer is 19 (note: i used "/" sign for "division")

How to solve #4 using substitution/ elimination method

kolezko [41]

3x+y = 4
x+y= 2 multiply all the elements of (x+y) by -1 & then add it up to the 1st equation
3x+y=4
-x-y =-2
----------
2x+0y =2 ==> x=2/2 =1 & replace x=1 by its value in any of the equation & you will get the value of y=1

2) 3x+y = 7
x+2y = 4
Follow the same methodology as before, but to eliminate y, multiply the 1st equation by (-2) and you will get x=2 & y=1
