Answer: 79.95 and 80.05
Step-by-step explanation: If the upper bound and lower bound is asked to a tenth then divide 0.1 by 2 and add 0.05 to 80.0 for the upper bound and minus 0.05 from 80.0 t get the lower bound.
The correct answer is D) a+2b.

Answer:
n=3/5
Step-by-step explanation:
3n−3+10+2n=10
Step 1: Simplify both sides of the equation.
3n−3+10+2n=10
3n+−3+10+2n=10
(3n+2n)+(−3+10)=10(Combine Like Terms)
5n+7=10
5n+7=10
Step 2: Subtract 7 from both sides.
5n+7−7=10−7
5n=3
Step 3: Divide both sides by 5.
5n

Answer:
Part A: 9.75x > 195
Part B: x > 20
Step-by-step explanation:
Let's say Mark works for x hours. For each hour he works, 9.75 dollars are added to Mark's salary. Therefore, for 1 hour, he gets $9.75, for 2 hours, he gets $9.75 + $9.75 = $9.75 * 2 = $19.50, and for x hours, he gets $9.75 * x as his salary.
We want his salary to be more than $195, so we have $9.75 * x (his salary) > $195, which can be written as 9.75x > 195
divide both sides by 9.75 to solve for x
x > 20
