Answer:
<h2>1) C. 8x + 2x = 10x</h2><h2>2) z = 5</h2><h2>3) y = 10</h2><h2>4) x = 1/2</h2><h2>5) x = 17</h2><h2>6) C. 1/4x + 4 = 3</h2><h2>
Step-by-step explanation:</h2>
<h3>1. <u>C. 8x + 2x = 10x</u></h3><h3 /><h3>2. 3z - 2 = 13</h3><h3>3z = 13 + 2</h3><h3>3z = 15</h3><h3><u>z = 5</u></h3><h3 /><h3>3. -5y - 10 = -60</h3><h3>-5y = -60 + 10</h3><h3>-5y = -50</h3><h3><u>y = 10</u></h3><h3 /><h3>4. 4x - 5 + 2x = -2</h3><h3>4x + 2x = -2 + 5</h3><h3>6x = 3</h3><h3><u>x = 1/2</u></h3><h3 /><h3>5. x - 8/3 = 3</h3><h3>x - 8 = 9</h3><h3>x = 9 + 8</h3><h3><u>x = 17</u></h3><h3 /><h3>6. <u>C. 1/4x + 4 = 3</u></h3><h3>(1/4 × -4/1) + 4 = 3</h3><h3>-1 + 4 = 3</h3><h3 />
The correct answer is option D.Which is ( x - 1 ).
<h3>What is a quadratic equation?</h3>
It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
The solution of the given quadratic equation will be:-
-2x² - 22x + 24 = 0
x ² + 11x - 12 = 0
x² + 12x - x + 12 = 0
x ( x + 12 ) -1 ( x + 12 ) = 0
( x -1 ) ( x + 12 ) = 0
Therefore the correct answer is option D.Which is ( x - 1 ).

Answer:
Both aren't proportional
Step-by-step explanation:
Whenever they are simplified they don't add up to the same fraction

Answer:
Inequality that represents the amount paid by neighbors of Dani will be
x ≤ 8 + (4 + 16)
Step-by-step explanation:
Let the neighbors of Dani paid her to take care of their bird = $x
Danny spent on an afternoon snack = $4
She paid the amount for a new book = $16
Now the amount left with her is at least $8.
Therefore, inequality which represents the amount paid by her neighbor will be
x - 4 - 16 ≤ 8
x ≤ 8 + (4 + 16)
