Answer:
-105
Step-by-step explanation:
Substituting is like "plug and chug", so we can plug in -2 into the expression and get 
, which simplifies into 21*-5, or -105. 
Answer:
1/x⁴
Step-by-step explanation:
=16(1/2x)⁴
=16(1/16x⁴)
=16×1/16x⁴(16 cancels)
=1/x⁴

To solve, set the equations equal to each other, so 4(2t-1)=2(3t+1). Next, distribute your 4 and 2, getting 8t-4=6t+2. Now, solve for t. 8t-4=6t+2, subtract 6t from both sides, 2t-4=2, add 4 to both sides, 2t=6, and divide 2, t=3. Now that you have your value of t, plug it into either equation, 4(2(3)-1)=4(6-1)=4(5)=20. This means they each picked 20 apples.
