Well the sum is 15+6=21. then you must do 81-21=60. So your answer must be t=60.
Answer:
The square root of 144 will be 12
Answer:

Step-by-step explanation:
Given

The inequality
From the question, we understand that;
the number of p used is more than the number of s
<em>more than means greater than.</em>
So, the inequality is:

To represent this on a number line.
First, we identify the position of s (i.e. scarf)
implies that p is any point to the right of s

An expression of the form

is called a "compound fraction"
Compound fractions can be written as simple fractions by multiplying c to a, and then adding the product to c as follows:

for example,

can be written as:

2.
when we subtract or add a fraction

from an integer k,
we first write k as a fraction with denominator n. We can do this as follows:

for example, if we want to subtract

from 8,
we first write 8 as a fraction with denominator 2:

3.
Thus,

4.
The simple fraction 7/2 is not an option, so we write it as a compound fraction as follows:

(So write 7 as the sum of the largest multiple of 2, smaller than 7 + what is left. In our case these numbers are 6 and 1, then proceed as shown)
