Answer: n=3
Step-by-step explanation:
6n-10=8
6n=18
n=3
You start by adding 10 to both sides and then divide both sides by 6.
Answer: A centroid of a triangle is the point where the three medians of the triangle meet that is what i got on my test hope this helps :)
Answer:
7
Step-by-step explanation:
5x = 35
Divide both sides by 5
x = 7
Whenever you have an equation like this, you have to simply divide both sides by the coefficient.
We can use a system of equations to solve this.
Notice that we are required to find 3 consecutive even integers.
This can be represented as x, y, and z, where x is the smallest integer, y is the next largest, and z is the largest of the three.
x = x
y = x + 2
z = y + 2
Take a moment to make sense of the above system of equations.
I can simplify the system a bit more by plugging in the second equation into the third one.
z = (x + 2) + 2
z = x + 4
Now the new system of equations is
x = x
y = x + 2
z = x + 2
Now for the second part of this problem. We are given this equation
2x + z = 268216
You may notice that we no longer need the second equation, y = x + 2. Also, the first equation is redundant, so we can ignore it.
That leaves us with this system:
z = x + 4
2x + z = 268216
What do you think we should do? We can plug in z to solve for x.
2x + (x + 4) = 268216
3x + 4 = 268216
3x = 268212
x = 89404
Now we know the first number in the sequence! Then we can find the other two numbers, because we know that the next numbers must be the next largest even numbers in sequence!
89404, 89406, and 89408 are your answers.
