Answer:
A and D
Step-by-step explanation:
In this question, we are asked to select the expressions that represent the number of vacation days per x days worked.
Now, to do this, what we simply first do is to get the number of days to takes to get one paid vacation. In the question , we are made to know that he gets 3 days paid vacation for 60 days of work. The number of days to get a single paid vacation would thus be 60/3 = 20 days. This means she gets one paid vacation in 20 days.
Now, we are told after working for x days, how many paid days vacation does she get. To know this, what we do is to first know the number of 20 days in x days. That would simply be x/20. This is the number of vacation days she gets in x days.
now, we check if there are similar options to this.
D is also correct. This is because x/20 is same as 0.005x
The equivalent value of the expression (1/2 x 15) is 7.5.
In mathematics, an algebraic expression is an expression built up from constant algebraic numbers, variables, and the algebraic operations.
Given is to solve the expression as -
1/2 x 15
We can write the expression as -
{x} = 1/2 x 15
{x} = 15/2
{x} = 7.5 x 2/2
{x} = 7.5
Therefore, the equivalent value of the expression (1/2 x 15) is 7.5.

Step-by-step explanation:
it's basically just 15 divided by 2
(sinx−tanx)(cosx−cotx)
=(sinx−sinxcosx)(cosx−cosxsinx)
=sinx(1−1cosx)cosx(1−1sinx)
=sinx(cosxcosx−1cosx)cosx(sinxsinx−1sinx)
=sinxcosx(cosx−1)cosxsinx(sinx−1)
=(cosx−1)(sinx−1)
