X is sugar
y is butter
z is total money
$0.80x + $1.25y = z
the total money spent if the Baker bought 6 pounds of butter and 20 pounds of sugar would be $23.50.
Answer:
25x25x25x25 Perfect square!
Step-by-step explanation:
Perfect square will always give you the most surface area.
So in this case...
100/4=25ft each side.
Thanks for letting me help!!
Step-by-step explanation:
d. 5x+3y=15 is the answer
coordinate 3,0 and 0,5
5•3 +(3•0)=15
5•0 +(3•5)=15
$30 dollars i thinks cause 40 minus 30 is ten
The student that simplified the expression incorrectly is student 2
<h3>How to determine the incorrect result?</h3>
The steps are given as:

Student 1:
- Step 1:

- Step 2:

- Step 3: 1 + tan²(Ф)
- Step 4: sec²(Ф)
Student 2:
- Step 1:

- Step 2:

- Step 3: sec²(Ф)/tan²(Ф)
- Step 4: csc²(Ф)
As a general trigonometry rule;

This means that student 1 is correct, while student 2 is not
The first error in student 2's workings is in step 2, where we have:

The above expression is not justified and cannot be proved by any trigonometry rule
Since the step 2 is incorrect, the other steps cannot be used.
Hence, the student that simplified the expression incorrectly is student 2
