49
Because 7x7 is 49 & 4+9=13
Answer:
3
Step-by-step explanation:
3
4/x = 6/(x+3)
6x = 4(x+3)
6x = 4x + 12
2x = 12
x = 6
P = (4 + 6) +(6+3) + 6
P = 10 + 9 + 6
P = 25
From this question, you can conclude:
1. There are 3 decimal
2. Decimal1 + decimal2+ decimal3= 2
3. The first decimal is 0.34
If you insert the 3rd into 2nd equation, it will become:
0.34+ decimal2+ decimal3= 2
decimal2+ decimal3= 2-0.34
decimal2+ decimal3= 1.56
If there are no rules regarding the second and third decimal, then you can use this both
1.01 + 0.55
0.78 + 0.78
