To express the number of pounds of pork Hilda bought using a decimal shows that she bought <u>11.3 pounds of pork.</u>
<h3>What is a decimal?</h3>
A decimal is a number that has a whole number and a fraction separated by a decimal point.
The decimal point is the dot that separates the whole number from the fractional part.
We can convert the mixed fraction to its improper fraction (by multiplying the whole number with the denominator and adding the numerator), and then divide the result by the denominator again.
<h3>Data and Calculations:</h3>
Total weight of meat bought = 21¹¹/₂₀ pounds (21.55)
Total weight of beef = 10¹/₄ pounds (10.25)
Therefore, the total weight of pork = 11.3 pounds (21.55 - 10.25)
Thus, the number of pounds of pork Hilda bought expressed as a decimal is <u>11.3 pounds of pork.</u>

Step-by-step explanation:
Multiply second equation by -1
-1 × (3x + 2y) = 3
-3x -3y = -3 now add this to the first equation
7x +2y = 17
(-3x-2y)= -3
7x +2y -3x -2y = 17 -3 (2y will eliminate -2y)
4x = 14
x = 7/2 now by using this information we found we can calculate the value for y
if 3x + 2y = 3 (replace x by 7/2)
3 ×(7/2)+2y = 3 ➡ 21/3 + 2y = 3 ➡ 2y = 3 - 21/3 ➡ 2ty = 15/2 ➡ y = 15/4

Let 
be Sarah's age. We know that the difference between Sarah's age and 44 -----> 
...Multiplied by 4 ----> 
equals 64-----> 
To solve the equation, we divide both sides by 4:
And add 44 to both sides:
