Hi!
So we have to make a system of equations here.
Let sibling 1 be O and sibling 2 be Y (for older and younger)
So:
O + Y = 64
O = 64 - Y
(Either one works)
The older sibling is 6 years older.
O = Y + 6
Make everything in terms of Y.
64 - Y = Y + 6
Same to both:
58 = 2y
2y = 58
Divide by 2 on both sides:
y = 29
Since the older sibling is 6 years older:
29 + 6 = 35
Y = 29
O = 35
Let me know if you have any questions.
 
        
             
        
        
        
Answer: k ≤ -4 or k ≥  
 
<u>Explanation:</u>
                       | 3k + 4 | ≥ 8
3k + 4 ≥ 8             or                3k + 4 ≤ -8
<u>       -4</u>  <u> -4  </u>                              <u>       -4</u>    <u>-4 </u> 
3k       ≥ 4              or                3k       ≤ -12 
<u>÷3       </u> <u>÷3  </u>                              <u> ÷3       </u>   <u>÷3 </u> 
 k        ≥  or                 k       ≤  -4
            or                 k       ≤  -4
