Answer:

x = 24

Step-by-step explanation:

∠ 13 and ∠ 14 are adjacent angles on a straight line and sum to 180° , then

4x + 11 + 3x + 1 = 180 , that is

7x + 12 = 180 ( subtract 12 from both sides )

7x = 168 ( divide both sides by 7 )

x = 24

If there are 420 students surveyed, which equation can be used to find the number of students s who prefer rap? Pop: 5/8 Jazz: 1

Aleksandr [31]

Answer:

B. $s=\dfrac{1}{4}\times420$

Step-by-step explanation:

Total number of students surveyed = 420

Of which only $\dfrac{1}{4}$ prefer rap.

So, the number of people who like rap is the product of the fraction of people who prefer rap and the total number of students.

$\text{Number of students who prefer rap}=s=\dfrac{1}{4}\times420\\\Rightarrow s=105$

The number of students that prefer rap is 105

So the equation is $s=\dfrac{1}{4}\times420$ .
