Answer:
-4y-7 i think
Step-by-step explanation:
sorry if im wrong but im pretty sure you combine -4 and -3, and -4 plus -3 is just -4 -3 so -7
Descriptions 1, 2, 3, and 5 are accurate, though 5 is ambiguous.
_____
Description 4 goes with (7x)² = 49x², not 7x².
Description 6 goes with 5·8 + x² + (2x + 8) = x² +2x +48, not 40x² +100x +40.
The description for 5 is accurate, but could also be applied to y² + 3(y - 4), which is why it can be considered to be ambiguous. There are a number of ways to resolve the ambiguity, but they were not used here.
First divide the price of the olive oil by the volume of the olive oil to find the price per ounce. 5.88/25oz=0.2352 dollars/ounce. Then you have to multiply the volume of the bottle by .60 to find what 60% of the volume is. 0.60x25=15 ounces. since in the first two weeks she used 15 ounces which has a price of 0.2352 dollars/ounce you have to multiply 15 by 0.2352 which equals 3.528 dollars.
Answer:
Hey there!
I would prefer method two.
Both methods give the right solution, but method two is more straightforward. Instead of distributing, you simply divide and don't need to do as much work.
Let me know if this helps :)
