The chess club can have at most 36 members. There are 3 times as many boys as girls in the chess club. Which inequality could be used to determine the possible number of girls, x, in the chess club? Answers included in the picture

3x+x ≤36

Step-by-step explanation:

Given that,

The chess club can have at most 36 members.

There are 3 times as many boys as girls in the chess club

Let there are x girls in the chess club.

Boys = 3x

ATQ,

3x+x ≤36

So, the correct inequality is (d) i.e. 3x+x ≤36

Sin of x does not change

Step-by-step explanation:

When we dilate a shape all the dimensions of the shape increases by a common factor.

Here the scale factor is 2 as we are dilating to two times big

So,

The 2 in the numerator and denominator get cancelled

giving us the same sin of x.

∴ Sin of x does not change
