Pls help me again sa math

1. x+7=12
2. x-10=-2
3.3(x+7)=24
sana masagot nyo po ito

 

Answer:

1.)x = 5

2.)x = 8

3.)x = 1

Step-by-step explanation:

1.) x + 7 = 12

x = 12 - 7

x = 5

2.)x - 10 = - 2

x = - 2 + 10

x = 8

3.)3 (x + 7) = 24

3x + 21 = 24

3x = 24 - 21

3x = 3

3x/3 = 3/3

x = 1

A = {0, 1, 2, 3} 2) B= the set of prime numbers less than 14 Prime numbers are numbers whose factors are exactly two, the number itself and 1.  Note that one the number 1 is not a prime number because it does not have two distinct factors. B = {2, 3, 5, 7, 11, 13} 3) C= the set of first three days of the week C= {Sunday, Monday, Tuesday}  ⇒ in the religious calendar or C = {Monday, Tuesday, Wednesday)  ⇒ the modern work-week calendar 4) D= (x/x is an even number less than 15} The even numbers are numbers with ones-digit 0,2,4,6,8.
