If you’re looking for x it would be -4/3
Answer:
Step-by-step explanation: I hope you understand this better
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Total amount to spend = $55
Amount of food and drinks purchased = $14.25
Amount put on gaming card = $(55 - 14.25) = $40.75
Cost per game = $1.25
Number of games (g) he can play
Number of games g:
Amount put on gaming card / cost per game
= $40.75 / $1.25
= 32.6 games
g ≤ 32
Answer:
<h2>x + 5 < 13</h2>
Step-by-step explanation:
x < 8 <em>add 5 to both sides</em>
x + 5 < 8 + 5
x + 5 < 13
The sum of any arithmetic sequence is the average of the first and last terms times the number of terms.
Any term in an arithmetic sequence is:
a(n)=a+d(n-1), where a=initial term, d=common difference, n=term number
So the first term is a, and the last term is a+d(n-1) so the sum can be expressed as:
s(n)(a+a+d(n-1))(n/2)
s(n)=(2a+dn-d)(n/2)
s(n)=(2an+dn^2-dn)/2
However we need to know how many terms are in the sequence.
a(n)=a+d(n-1), and we know a=3 and d=2 and a(n)=21 so
21=3+2(n-1)
18=2(n-1)
9=n-1
10=n so there are 10 terms in the sequence.
s(n)=(2an+dn^2-dn)/2, becomes, a=3, d=2, n=10
s(10)=(2*3*10+2*10^2-2*10)/2
s(10)=(60+200-20)/2
s(10)=240/2
s(10)=120
