Answer:
4 paysmenets
Step-by-step explanation:
4500/250=18 paymentent
250x4= 1,000
A
Explanation
She gets 11 for every hour but it doesn’t say how many hours so we put a variable ( in this case x ) so we have 11x and she revived $6 extra since it was received and not taken away we add 11x +6 and since it’s an equation we put 11x +6 = $39
For extra help x is equal to 3
Working step by step I first see all my different groups then add them all together
so
12 - cats
15 - dogs
6 - both
9 - neither
12 students + 15 students + 6 students + 9 students = 42 students
therefore 42 students are in the class
16 + 10 + 3 + 12 = 41
I’m sorry if i got it wrong!
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

Answer:
Fraction: 10/9 mixed number: 1 1/9 decimal: 1.1
Step-by-step explanation:
1. Combine 4/5 with x
4x/5+4/3=2x
move all the terms that contain x in them to your left side of the equation
-6x/5 + 4/3 =0
subtract 4/3 from both sides
-6x/5 = 4/3
multiply both side by -5/6
-5/6 (-6x/5)= -5/6 (-4/3)
x=10/9 x=1.1 x= 1 1/9
