Answer:
x = -1
Step-by-step explanation:
Step 1: Write equation
-4(-5x + 2) - 3x - 5 = -30
Step 2: Solve for <em>x</em>
<u>Distribute -4:</u> 20x - 8 - 3x - 5 = -30
<u>Combine like terms:</u> 17x - 13 = -30
<u>Add 13 on both sides:</u> 17x = -17
<u>Divide both sides by 17:</u> x = -1
Answer:
A
Step-by-step explanation:
<h3><em><u>A. 4xy-16</u></em></h3>
<em><u>=4(xy−4)</u></em>
<h3 /><h3><em><u>B. xy+2xy-x</u></em></h3>
<em><u>3xy−x</u></em>
<em><u>=x(3y−1)</u></em>
<h3><em><u>C. 2x²-18x+12</u></em></h3>
<em><u>2x²</u></em><em><u>−18x+12</u></em>
<em><u>=2(</u></em><em><u>x²</u></em><em><u>−9x+6)</u></em>
<h3><em><u>D. 5xy+20x-9y-36</u></em></h3>
<em><u>5xy+20x−9y−36</u></em>
<em><u>=(y+4)(5x−9)</u></em>
Answer:
<em>(1/6)(-10x - 4) = -4
</em>
Step-by-step explanation:
(1/6)(-3x - 24) = -4
=> -3x - 24 = -4 x 6
=> -3x - 24 = -24
=> -3x = 24 - 24
=> -3x = 0
=> x = 0 (not 2) => Incorrect option
(1/6)(-5x - 8) = -4
=> -5x - 8 = -4 x 6
=> -5x - 8 = -24
=> -5x = 8 - 24
=> -5x = -16
=> x = 16/5 (not 2) => Incorrect option
(1/6)(-10x - 4) = -4
=> -10x - 4 = -4 x 6
=> -10x - 4 = -24
=> -10x = 4 - 24
=> -10x = -20
=> x = 2 => Correct option
(1/6)(-12x - 16) = -4
=> -12x - 16 = -4 x 6
=> -12x - 16 = -24
=> -12x = 16 - 24
=> -12x = 8
=> x = -3/4 (not 2) => Incorrect option
=> Option C is correct
Hope this helps!
