Answer: 5 times
Step-by-step explanation:
Let the number of times that he saved $75 be x.
Let the number of times that he saved $150 be y.
Therefore, based on the information given in the question, we can form an equation which will be:
x + y = 8 ...... i
75x + 150y = 825 ....... ii
From equation I,
x + y = 8
y = 8 - x....... iiii
Put equation iii into ii and this will be:
75x + 150y = 825
75x + 150(8 - x) = 825
75x + 1200 - 150x = 825
75x - 150x = 825 - 1200
-75x = -375
x = 375/75
x = 5
He saved $75 5times from his paycheck.
Multiply both by 2,and you have 6/10 which is equivalent to 3/5.
Answer:
see explanation
Step-by-step explanation:
If the sequence is arithmetic then there will be a common difference d between consecutive terms, that is
8 - 4 = 4
16 - 8 = 8
22 - 16 = 6
32 - 22 = 10
The difference between terms is not common
Hence this is not an arithmetic sequence
The answer is A
start by isolating the y variable
