2,3,6 because 2 and 3 cant equal 6
<span>We convert the sentences to mathematical expressions as follows
"</span>Four times the sum of the least and greatest integers" : 4[n+(n+2)]
"is 12 less than three times the least integer": = 3n-12
So we have:
4[n+(n+2)]=3n-12 (this is the equation)
4[2n+2]=3n-12
8n+8=3n-12
8n-3n=-12-8
5n=-20
n=-20/5=-4
Answer: the equation is 4[n+(n+2)]=3n-12 , the least integer is -4
The circle is open on 2. shade right on the nimber line
Answer: C. 2n+1
Step-by-step explanation:
The sequence of numbers is
3,5,7,9
The terms are increasing at a linear rate. This means that it is an arithmetic progression. The difference between two successive terms is constant. This is the common difference. The formula for the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
Tn is the nth term of the arithmetic sequence.
d is the common difference of the arithmetic sequence.
n is the number of terms in the arithmetic sequence.
From the information given
a = 3
d = 5 - 3 = 7 - 5 = 9 - 7 = 2
Tn = 3 + 2(n - 1)
Tn = 3 + 2n - 2
Tn = 3 - 2 + 2n
Tn = 2n + 1
Answer:
12.5%
Step-by-step explanation:
percent change is calculated as
x 100
change = 32 − 28 = 4 pages
x 100% = 
% = 12.5 %
