I think your answer will be A. Aleta can buy 10 tops if she only buys 2 pair of pants.
for 10(15)+2(30)=$210
There would be 35 rulers.
In order to solve this, use cross multiplication.
6/10 = 21/x -----> cross multiply
10*21 = 6*x
210 = 6x
35 = x
Answer:

Step-by-step explanation:
we are given equation for position function as

Since, we have to find acceleration
For finding acceleration , we will find second derivative




now, we can find derivative again




Firstly, we will set velocity =0
and then we can solve for t

we get

now, we can plug that into acceleration
and we get


Answer:
the order is
2,4,1,3
(the 1st answer is the 2nd option)
Use a proportional that will give you x=4
