Answer:
91
Step-by-step explanation:
When x goes from 1 to 2, y increases by 4 from -5 to -1
When x goes from 2 to 3, y increases by 5 from -1 to 3
We are adding 4 each step
The formula for an arithmetic sequence is
an = a1 + d(n-1)
where a1 is the first term a1 =-5
d is the common difference or what we add each time = 4
and n is the term number n=25
a25 = -5 + 4(25-1)
a25 = -5+4(24)
-5 +96
91
The 25th term is 91
Remark
The trick here is to realize that you have to find the number both have in order to find the difference. That means you take (effectively) 3/8 and 5/8 to find out how much each of them has. The 8 stands for the 136
Step One
Find the number of stamps Alex has. Remember his ratio is the smaller so he will have 3/8
Alex = 3/8 * 136
Alex = 408/8 = 51
Step 2
Find the number that Freddy has.
The total is 136
<u>Formula</u>
Freddy = Total - Alex
Freddy = 136 - 51
Freddy = 85
<u>Check</u>
Let us see if 5/8 * 136 = 85
5*136/8 = 680 / 8 = 85 So your answers are correct.
Difference
Difference = 85 - 51 = 34 which is how many more stamps Freddy has than Alex.
Answer:
x cannot equal 3
Step-by-step explanation:
you cannot have a zero on the denominator so when the denominator equal zero, thats your domain restriction.
7(p)
p=3
7(3)
the answer is 21.
5/9p = -10
Multiply 5 on both sides
9p = -50
Divide both sides by 9
Final Answer: p= 5.555555555555556
