Answer:
9+20t
Step-by-step explanation:
Look at the terms and see which has t and which is a number when you see like terms, add them or subtract them together to get like terms.
36/20 or simplified and as a mixed number would be:
1 and16/20
Answer:
1
Step-by-step explanation:
1. Convert the mixed number to an improper fraction to match the rest of the problem (this just makes it easier for now, the answer will still be a mixed number)
-1
becomes 
2. Re-write the new equation. When there is a "+" in front of a set of parentheses the expression doesn't change aside from removing the plus signs.
The new equation becomes

3. Calculate. Just work out the new expression.
The answer is 
4. Convert to a simplified mixed decimal.
27 goes into 20 once with seven left over, making the answer 1
Answer:
It should be $12168.75
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.25%/100 = 0.0425 per year,
then, solving our equation
I = 11000 × 0.0425 × 2.5 = 1168.75
I = $ 1,168.75
The simple interest accumulated
on a principal of $ 11,000.00
at a rate of 4.25% per year
for 2.5 years is $ 1,168.75.
1,168.75 + 11000 = 12168.75
