Answer:
-4
Step-by-step explanation:
think of it like this -6+2
Step-by-step explanation:
answer is 8 1by 3 as mixed fraction
steps:
three consecutive numbers = x,x+1,x+2
x+x+1+x+2 = 75
3x+3 = 75
3x = 75÷ 3
3x = 25
x= 25÷3
= 8 1 by 3 as mixed fraction
Answer:
2n^2 + n + 4.
Step-by-step explanation:
7, 14, 25, 40, 59
The differences are 7, 11, 15, 19 which is arithmetic sequence so the given sequence is quadratic.
Compile a table:
n 1 2 3 4 5
term 7 14 25 40 59
Diff: 7 11 15 19
Diff: 4 4 4 - this indicates that first part is 2n^2.
2n^2 2 8 18 32 50
term-2n^2 5 6 7 8 9
- the nth term for the last sequence is 5+ (n - 1)d =
= 5 + (n - 1)* 1
= n + 4.
So nth term for the original sequence is 2n^2 + n + 4.
GCF = 20
Reduce the fraction by dividing
the numerator and denominator by 20
and get the simplified answer
<span><span>20 ÷ 20=1 || 80 ÷ 20</span>=4
<em>1/4</em> is your answer! :D</span>
Multiply the numerator together and denominator together.
51 x 1 and 5 x 2
51/ 10
after you simplify, you get 5 1/10
(to double check you do 10 x 5 + 1 and that should give you 51 which is the numerator)
