Answer:
10x+ y
Step-by-step explanation:
The unit's digit is y and the ten's digit is x.
The ten's digit has a zero placed beside it .
So multiply x by 10 giving 10 x and then add the unit's digit .
This wil give 10x+ y
The number is 10 x + y
This can be elaborated through the use of numbers . Suppose we have unit's digit as 6 and the ten's digit as 5.
Multiply 10 by 5 and add 6
5*10 +6= 50+6= 56
The answer to that would be 15 13/30. You have to change the denominators, as well as the numerators, to fit both fractions. I did 10 * 3 = 30 & 15 * 2 = 30. That resulted in me getting 3 * 3 = 9 + 2 * 2 = 4, which equals 13.
I hope this answer helped you! If you have any further questions or concerns, feel free to ask! :)
Answer:
x = 100
Step-by-step explanation:
The ratios of long side to hypotenuse are the same for all these triangles.
x/(x+10) = (x+10)/(x+21)
x^2 +21x = x^2 +20x +100 . . . . . multiply by (x+10)(x+21), expand
x = 100 . . . . . . . . . . . . . . . . subtract x^2 +20x
Answer:
540
Step-by-step explanation:
The multiples of 45 are 9,3,3,1
The multiples of 60 are 12,4,2,1
The multiples of 135 are 27,9,9,9,3
Therefore the LCM can be calculated as follows
= 5×3×2×2×3×3
= 540
Hence the LCM is 540
