$6\frac{1}{2}$ hours more.

Step-by-step explanation:

We have been given that Linda planned to spend 9 hours practicing piano this week. By Tuesday, she had spent 2 1/2 hours practicing.

To find number of hours Linda needs to practice to reach her goal, we will subtract 2 1/2 from 9 as:

$9-2\frac{1}{2}$

Convert mixed fraction into improper fraction:

$2\frac{1}{2}\Rightarrow \frac{2\times 2+1}{2}=\frac{4+1}{2}=\frac{5}{2}$

$9-2\frac{1}{2}\Rightarrow 9-\frac{5}{2}$

$\frac{9*2}{2}-\frac{5}{2}$

$\frac{18}{2}-\frac{5}{2}$

Combine numerators:

$\frac{18-5}{2}$

$\frac{13}{2}$

$6\frac{1}{2}$

Therefore, Linda needs to practice $6\frac{1}{2}$ hours more to reach her goal.

Mathematics

The two consecutive integers you are looking for are 9 and 10.

Step-by-step explanation:

Consecutive numbers are numbers that are after or before one another when you count upwards or downwards. As 9 and 10 follow this rule, they are consecutive integers.

Our next method of proof is to add the two together, as the "sum" is the number you receive when you add two numbers together.

9+10=19

The answer we receive is the one we are looking for while also following the requirement of being the sum of consecutive numbers, thus the integers you are looking for are 9 and 10.
