Help!<br> Find the value of x for which ABCD must be a parallelogram.
Stolb23 [73]
3
In a parallelogram, the diagonals (the lines inside from corner to corner) bisect each other. That means the two halves of the diagonal are equal to each other.
So
-9-6x=x-30
-9-6x+6x=x-30+6x
-9=7x-30
21=7x
x=3

Please help me, I don’t understand
White raven [17]

Answer:

73, 74, 75

Step-by-step explanation:

So the sum of three consecutive integers is 222.

Let's let the first integer be n.

Then the second integer <em>must</em> be (n+1).

And the third integer must be (n+2).

They total 222, thus:

n+(n+1)+(n+2)=222

Combine like terms:

3n+3=222

Subtract 3 from both sides:

3n=219

Divide both sides by 3:

n=73

So, the first integer is 73.

So our sequence is 73, 74, and 75.

And we're done!
