Let x be Gabrielle’s age
Let y be Mikhail’s age
X=2y and x+y=84 so...
X=2y and x=84-y so by substitution of x,
2y=84-y
3y=84
Y=28

So Mikhail is 28
And Gabrielle is 56

Answer:

28

Step-by-step explanation:

Mikhail's age:x

Gabrielle's age:2x

x+2x=84

3x=84

x=84÷3

x=28

Using the ruler postulate, find the distance between –9 and 2.
gulaghasi [49]

Answer:

11 units

Step-by-step explanation:

According to ruler postulate, if there are two points A with coordinate a

and point B with coordinate b, \

then distance ab is given by subtracting coordinate in any order i.e it can be (a-b) or (b-a) and then take the absolute value value of it.

mathematically it can be represented as

AB = |a-b| or |b-a|

_________________________________________

in the given problem points are -9 and 2

thus distance

distance between –9 and 2  = |-9 -2| = |-11|  = 11

absolute value of -11 is 11

alternatively, distance can be calculated as

distance between –9 and 2  = |2 -(-9) | = |2 + 9 | = |-11|  = 11

You start at (4, -6), then you move to the left three units and down 6 units, now you are at
natta225 [31]

Answer:

(1, - 12 )

Step-by-step explanation:

Moving left 3 units means subtracting 3 from the x- coordinate

Moving down 6 units means subtracting 6 from the y- coordinate

(4, - 6 ) → (4 - 3, - 6 - 6 ) → (1, - 12 )

The sum of 3 consecutive odd integers is 36. Whal<br> consecutive odd integers
IgorC [24]

\huge\pink{Answer}

Any odd number can be represented with 2n+1 where n is a whole number. Also, since the next consecutive number will be even (2n+1+1), then the next consecutive odd number must be 2n+1+2, or 2n+3. Since consecutive odd numbers are separated by 2, then the previous odd number should be 2n-1. So:

<h3>2n-1+2n+1+2n+3=36</h3><h3>6n+3=36</h3><h3>6n+3-3=36-3</h3><h3>6n/3=33/3</h3><h3>2n=11</h3>

Now in order to find three odd consecutive numbers that will sum to 36, you must be able to divide 11 evenly by 2, and have a whole number as a result. This is impossible, so there aren't any 3 odd numbers that will sum to 36.
