In a class there are 15 students. 8 of them like playing soccer , 6 of them like swimming , and 2 like both and swimming and playing soccer. How many students do not like either playing soccer or swimming?

3 students

Step-by-step explanation:

As shown in the Venn diagram, let

x be the number of students who do not like either playing soccer or swimming

U=[Total number of students in the class]

A=[Number of students who like playing soccer]

B=[Number of students who like swimming ]

We write mathematically equation in terms of x, for the problem, and solve for x value.

Subtract 12 from both sides.

Hence, be the number of students who do not like either playing soccer or swimming is 3.

8y^50

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
