x=4
Step-by-step explanation:
4(-6+5x)=24+8x
open the bracket
-24+20x=24+8x
collect like terms
20x-8x=24+24
12x=48
divide both sides by 12
12x/12 = 48/12
x= 4
-7+7n=2(-7+7n)
open the brackets
-7+7n=-14+14n
collect like terms
14n-7n=-14+7
7n=-7
divide through by 7
n=-1
Step-by-step explanation:
The nth term just mean how to work out the next number in he series. In this series of numbers, you have to square three n and add it onto 10 n to do this.
N is the term- the number it comes in the sequence.
Example:
2 3 4 5 6
2= the first terof the sequence
3= second term
4=3rd term
And so on
To work out what the next term is (6th term) you use this expression:
N+1
The first term is 2. As it is the first n=1. 1+1=2 so that works
The seco d term is 3. As it is the second term n=2. 2+1+3 so that works
And so on
This might help
But you have to do the rest
Answer: 16 flowers are pink.
Step-by-step explanation:
According to the exercise, the total number of flowers in Mrs. Elliott's garden is:

Answer:
They are all multiples of 9
Step-by-step explanation:
You need to find the greatest common factor of each one. When you do, the 9 is the biggest one. The multiples of 9 are: 9,18,27,36 which includes all of the numbers of flowers.
18 = 1,2,3,6,9,18
27=1,3,9,27
36=1,2,3,4,6,9,12,18,36
