Answer:
D
Step-by-step explanation:
Its 5x (on bottom row, its the simplest way to put it), and 625 x 5 = 3125, then 3215 x 5 = 15625. So its D.
7+(x+5) would be the answer because sum means addition and it says x and 5. then it says 7 plus that so you put 7. In reality you wouldn't need parenthesis, but if you want it to match the phrase, you can put it in parenthesis.
1 mile = 640 acres 640+25=665 665•1,500=997,500
the total cost is $997,500
Your rate of change would be 3/4 lb/week.
You could model this with a linear eq:
y = 8+ 3/4x
