Answer: B.
First, we have to have a question for this problem to create a solution. So, the example sentence is how many granola bars does each student get.
Second, an algebraic expression has a variable in it. So since we are trying to find the number of students, the variable is s.
From looking at C and D, we can already eliminate them. This question has mostly multiplication and division words in it, so it can't be addition and multiplication.
Now, we only have A and B left. A tip on how to figure this out is reading the word problem out thoroughly. I will use B as an example. 5 boxes of granola bars were multiplied by the number of granola bars each student got. From reading this, it makes more sense. But it does change the example sentence, though.
I hope this helped and this is the right answer!
Answer:
3,-2
Step-by-step explanation:
Total amount she wants to raise = $3200
Amount she'll get for each kilometer = $35
So, number of kilometers she need to run
= Total amount she wants to raise/Amount she'll get for each kilometer
= $3200/$35
= 91.42....
Since her sponser is will donate only for whole kilometers she'll have to run 92 km.
Both 2 and 6 are divisible by 2, so you would divide them by 2 and your fraction would be reduced to 1/3. You would get that answer by simply reducing the fraction.
Answer:
A(t) = -1.8t - 4.5
Step-by-step explanation:
Let the starting level of Mr. Mole is 'b'.
Since Mr. Mole is descending with respect to the ground, at the rate = 1.8 meters per minute
After time 't' altitude of Mr. Mole will be = b - 1.8t
If we represent the altitude of Mr. Mole with A(t).
Then the equation will be,
A(t) = b - 1.8t
Or, A(t) = -1.8t + b
At the time t = 5 minutes, his altitude was 13.5 meters.
So, -13.5 = -1.8×(5) + b
b = -13.5 + 9
b = -4.5
Now we substitute the value of b in the equation.
A(t) = -1.8t - 4.5
