Step-by-step explanation:
2x - 5 = 7
2x = 7 + 5
2x = 12
x = 12 / 2
x = 6
Hope it will help :)
Answer:
x = 8
Step-by-step explanation:
To get x, we will use the pythagoras theorem;
10² = x² + (12/2)²
100 = x² + 6²
100 = x² + 36
100 - 36 = x²
64 = x²
Swap
x² = 64
x =√64
x = 8
Hence the value of x is 8
To solve this, it is easiest to find the least common multiple of the denominators which is 24. Now we can rewrite our fractions.
