Answer: I believe your answer is 17.

Step-by-step explanation: 3a+5+8

Since there is only one a you can turn the a into a 1. So it’s now 3+1+5+8=17 it’s either that or it’s 3x1+5+8= 16

So your answer is either 16 or 17 I believe. Hope I helped!

50 students were asked what they did last night. 16 said they read a book, 41 said they watched TV, 7 said they did neither, how
Kamila [148]

Answer:

14 students

Step-by-step explanation:

Given

Let:

b \to read a book

t \to watched TV

So, we have:

n = 50 -- total

b = 16

t = 41

none = 7

Required

Students that did both (x)

This is calculated using:

Total = Books\ only + TV\ only + Both + None

So, we have:

n = (b - x) + (t - x) + x + none

This gives:

50 = (16 - x) + (41 - x) + x + 7

Open brackets

50 = 16 - x + 41 - x + x + 7

50 = 16 - x + 41 +7

Collect like terms

x = 16 - 50 + 41 +7

x = 14

<em>Hence, 14 students did both</em>
