Answer:
1.Let the number be x
5x + 50 = 200 – x
2. Let the number be x
50 – 4x = 15 + x
4. Let the smaller number be x
and the larger number be 5 – 2x
X + 5 – 2x = 70
X + 5 = 70
X = 70 -5
X = 65
1. Let the smallest consecutive number be x
The largest be x + 2
2x = 12 + x + 2
2x – x = 14
x = 14
The numbers are
14, 15, 16
2. Let the smallest be x
The middle be x + 1
The largest be x+ 2
X + x+ 1 = 24 + x + 2
2x + 1 = 26 + x
2x – x = 26 -1
X = 25
The numbers are
25 , 26, 27
3. Let the first even number be x
Let the second even number be x + 2
Let the third even number be x+ 4
= x + 2 (x + 2) = 20 + x + 4
= x + 2x + 4 = 20 + x + 4
= 3x + 4 = 24 + x
= 3x – x = 24 -4
= 2x = 20
= x = 20/2
X = 10
The even numbers are
10. 12, 14
