Answer:
In mathematics, there are some properties of numbers that are handy to know. For example, the identity property of multiplication says that any number times one is equal to the original number. So, according to that property 5 x 1 = 5.
Step-by-step explanation:
Answer:
c
Step-by-step explanation:associative: a+(b+c)=(a+b)+c
commutative: a+b=b+a
distributive: a(b+c)=ab+ac
inverse: I think it is a times 1/a=1, doesn't matter
Answer:
b = -27
Step-by-step explanation:
-1/3 b = 9
Multiply each side by -3
-3 * -1/3 b = -3 * 9
b = -27
On first week
Quantity of tomato = 25 tons
profit per ton = $250
So if she sells tomato on first week then total profit = 25 * 250 = $6250
On second week
Quantity of tomato =27 ton
profit per kg =$ 235
So if she sells tomato on second week then total profit =27* 235= $6345
On third week
Quantity of tomato = 29 ton
Profit per kg = $220
So if she sells tomato on third week then total profit = 29*220 = $6380
Now consider fourth week
Quantity of tomato =31 ton
Price per kg = $205
So if she sells tomato on fourth week then total profit =31*205 = $6355
so she must ship her tomatoes on third week i.e she will attain $ 6380 as profit.
