Answer:
with
Step-by-step explanation:
We can study what happens day by day starting with day one (1) to understand how the recursive relation can be constructed:
Day # Number of stamps What is added relative to previous day
1 d1 = 80 + 1 = 81
2 d2 = 81 + 2 = 83 d2 = d1 + 2
3 d3 = 83 + 4 = 87 d3 = d2 +
4 d4 = 87 + 8 = 95 d4 = d3 +
5 d5 = 95 + 16 = 111 d5 = d4 +
6 d6 = 111 + 32 = 143 d6 = d5 +
(n+1) d(n+1) = dn +
The definite value for p is 9.
But how are 8, 7, or 6 the value of p?
I personally think that you should contact the teacher who made this question. He/She probably meant to say What IS the value for p?
You use algebra to get the value for p:
20p-45 = 9p + 5p
Start solving from there.
Answer:
annual interest= $125, over 4 years=$500
Step-by-step explanation:
2500/20=125 or break the 2500 by 100 and 5% of 100 is 5. 5x25= 125
The answer is 10 because the student student did not follow order of op. This means that the student added 25 and 5 together then dived that. However he should have divided 25 by 5 first and then added 5
Answer:
Step-by-step explanation:
This can be modelled with the variable x to represent the "groups"
3x + 2
Multiplifcation means groups of.
3x is 3 times x, which is 3 groups of x.
