Mathematics

Answer:

Savannah's age = 6 years

Step-by-step explanation:

Let

Savannah's age = x

Dylan's age = 15

Dylan is 15, which is 3 years older than twice his sister Savannah’s age

Dylan = 2x + 3

Find Savannah's age

2x + 3 = 15

Subtract 3 from both sides

2x + 3 - 3 = 15 - 3

2x = 12

Divide both sides by 2

2x / 2 = 12 / 2

x = 6

Therefore,

Savannah's age = x

= 6 years

Dylan's age = 2x +3

= 2*6 + 3

= 12 + 3

= 15 years

I am between 24 and 34.you say my name when you count by twos from zero . you say my name when you count by fives from zero. wha
Mariulka [41]
You would have to be 30 because multiples of 5 would only be 25 and 30 inbetween those numbers, and 25 is not an even number which it must be if you can say the number counting by 2s

X-1/2=15 1/4 whats x and show work
ikadub [295]
X-1/2=15 1/4

15  1/4 = 15*4 + 1 = 61/4

61/4

x - 1/2 = 61/4
    +1/2   +1/2

61/4 + 2/4 = 63/4

x = 63/4

Is the LCM of a pair of numbers ever equal to one of the numbers?
den301095 [7]

Yes.

For example, the LCM of 12 and 36 is 36, because factoring these numbers gives

12 = 2^2 * 3

36 = 2^2 * 3^2

So, to match them, just multiply the twelve by 3, then they're both 36.

Answer:

  • 3n+6 (n = smallest)
  • 3n (n = middle)

Step-by-step explanation:

The usual method for doing this is to let n represent the smallest one. Then the three integers are ...

  n, n+2, and n+4

and their sum is ...

  (n) +(n+2) +(n+4) = 3n+6 . . . . sum of 3 consecutive odd integers (n = smallest)

_____

Personally, for consecutive number problems, I prefer to let the variable represent the average value. If n is the average value of 3 consecutive odd integers, is is the middle integer. Of course, the sum will be 3 times the average:

  (n-2) +(n) +(n+2) = 3n . . . . sum of 3 consecutive odd integers (n = middle one)
