7 because 7x3= 21 and 21 + the 7 cats comes to an equal 28
The operator 
is transitive, which means exactly that
That's the only thing you can deduce from your statement.
Answer:
A 500 mg bag of prepackage seeds costing $3.95
Step-by-step explanation:
First, you need to know the amoun of grams in 1/2 kg to find the cost of the sunflower seeds:
1 kg→1000 grams
1/2 kg→ x
x=(1000*(1/2))/1
x= 1000/2
x= 500 grams
Second, you have to find the cost of 500 grams of sunflower seeds:
100 grams → $0.70
500 grams→ x
x=(500 *0.70)/100
x= 3.5
According to this, 1/2 kg of of bulk sunflower seeds cost $3.5 which is cheaper than the 500 mg bag of prepackage seeds that cost $3.95 and this means that the better value is 1/2 kg of bulk sunflower seeds as the amount is also higher as 500 mg is equal to 0.5 grams.
The rule for the product of similar bases with exponents:
(a^b)(a^c)=a^(b+c)
(-5*6)(a^1)(a^8)
(-30)(a^(1+8))
-30a^9
Factors of -48 that add up to 2
-6 and 8
So these are the factors (x + 8)(x - 6)
If you have any of those as th option, it is the answer.
