Answer:
b
Step-by-step explanation:
9 5/10 -- 1/23 = 43546 = 92146≅ 9.456522
Calculation steps
Conversion a mixed number to a improper fraction: 9 5/10 = 9 · 10 + 510= 9510
Subtract: 9510 - 123 = 95 · 2310 · 23 - 1 · 1023 · 10 = 2185230 - 10230 = 2185 - 10230 = 2175230 = 43546
The common denominator you can calculate as the least common multiple of the both denominators - LCM(10, 23) = 230
Answer:
<em> Linear model
</em>
The function f(x) which represents the total amount in the savings account in x months is given by: f(x)=25x+2000
Step-by-step explanation:
Given:
Enrico deposited $2000 in a savings account.
Each month he will deposit additional $25.
This shows that the rate at which the amount is increasing each month is constant.
Therefore, the model will be linear with a slope 25.
So , if x represents the number of months.
and f(x) represents the corresponding amount in the account.
Then the function f(x) is given by: f(x)=25x+2000
