The LCD of 2/5 + k/4 = 9/10 is 20. Applying this LCD, we get:
8 + 5k = 18. Subtracting 8 from both sides: 5k = 10. Then k = 10/5, or k = 2.
Answer: 25
Step-by-step explanation: 8*5=40, so multiply 5 by 5. Or, to put it another way:
5/8 = 25/40
The answer is 2/15 because it can either be 4 and 5 or 3 and 6
Answer:
-10
Step-by-step explanation:
Let x = number
10 less than a number is the same number doubled
x-10 = 2x
Subtract x from each side
x-10-x = 2x-x
-10 = x
The number is -10
If 1 inch is 13.5 feet, then 5 inches = (13.5 * 5) = 67.5 ft
