Answer:
it is 4 because if you multiply each x-value by 4, you'll get they y-value underneath it:)

<h2>
Inequality</h2><h3>-7x > 21</h3>
<em>Divide both sides by −7. Since −7 is <0, the inequality direction is changed.</em>
<h3>x< 21/-7</h3>
<em>Divide 21 by −7 to get −3. </em>
<h3>x < −3</h3>

2+2=4 because if you have 2 and you add another 2 you will have 4
Answer:
Adult: 50 tickets
Child: 34 tickets
Step-by-step explanation:
Let a be the amount of adult tickets
Let c be the amount of child tickets
Equation:
a + c = 84
14a + 9c = 1,006
Step 1: Multiply a + c = 84 with -9, to canceled c.
-9 (a + c = 84) → -9a - 9c = -756
14a + 9c = 1006 → 14a + 9c = 1006
Step 2: Combined the 2 equation together, and solved it.
-9a - 9c = -756
<u>14a + 9c = 1006</u>
<u> 5a</u> = <u>250</u>
5 5
a = 50
Step 3: Plug 50 into the one of the equation, and solved it.
a + c = 84 → 50 + c = 84
<u>-50 -50</u>
c = 34
Answer: Adult tickets (a) = 50 and Child tickets (c) = 34
To check the answer plug the two number into the equation ( Make sure to add 50 for a and 34 for c).
