In order to solve this problem, we must solve an equation.

First, we need to define our unknown.

Let's call our number "n".


So, the sum of the number and 6 is the same as saying n+6

Then we need to multiply it by 2 (since it's twice the sum)

2(n+6)

This whole thing is equal to three times of the difference of the number and 8

n-8 is equal to the difference between the number and 8, then we need to multiply it by three.

3(n-8)

now, we set both sides equal and solve

2(n+6)=3(n-8)\\2n+12=3(n-8)\\2n+12=3n-24\\12=n-24\\36=n

The number is 36

Nancy bought an extra-large bag of 1,288 beads to make necklaces. When she got home, she found another bag with 784 beads in it.
tekilochka [14]

We are given

Nancy bought an extra-large bag of 1,288 beads to make necklaces

When she got home, she found another bag with 784 beads in it

so, total number of beads =1288+784

total number of beads =2072

now, we have

For one necklace , 56 beads are required

so, 56 beads = 1 necklace

1 bead=\frac{1}{56}necklace

for 2072 beads

2072*1 beads=2072*\frac{1}{56}necklace

2072 beads=37necklace

so,

number of necklaces she can make is 37..........Answer

What is the coordinate of the vertex? Help
Ilya [14]
Answer: (6,-20)

Explanation:
The equation f(x) = -(x-6)^2 - 20 is the same as y = -1(x-6)^2 + (-20)
It is in the form y = a(x-h)^2 + k
The vertex is (h,k) 
In this case, h = 6 and k = -20
So that's why the vertex is (6,-20)
