2. the sum of three number is 68. the largest number is 6 less than twice the smallest , and the middle number is 10 less than the largest . find the tree numbers!
eg: smallest = x
middle = y
largest = z
z = 2x-6
y = z-10
x+y+z = 68
x+z-10+2x-6 = 68
x+2x-6-10+2x-6 = 68
5x-22 = 68
5x = 68+22
5x = 90
x = 90:5
x = 18
z = 2x-6
z = 2.18-6
z = 30
y = z-10
y = 30-10
y = 20
The smallest is 18
The middle is 20
The largest is 30

8. The sum of three consecutive even numbers is less than 140. Find the largest possible number and express it as a product of its prime factors.
Jawab:
2 x 2 x2 x 2 x3 = 48
Penjelasan dengan langkah-langkah:
a + b + c < 140
where a<b<c and a,b,c are consecutive even numbers
possible solutions are between 40 and 50
40 + 40 + 40 = 120
50 +50 +50 = 150
then, the closest solutions will be
44 + 46 + 48 = 138
the largest number is 48
9. the biggest composite number less than 200

20. The sum of three number is 109The second number is 4 times the first and the third is 8 less than the second . Find the three number.
Jawaban :
Pembahasan :
a + b + c = 109
b = 4a
c = b - 8
a + b + c = 109
a + 4a + b - 8 = 109
a + 4a + 4a - 8 = 109
9a - 8 = 109
9a = 109 + 8
9a = 117
a = 13
b = 4a
b = 4(13)
b = 52
c = b - 8
c = 52 - 8
