Answer:
72%
Step-by-step explanation:
There are a total of 50 quizzes in the year
From the first 20, the student passes 60%. This makes a total of

12 passes
Out of the remaining 30 quizzes the student passes in 80% of them. This makes a total of

24 passes
Adding the two values
12 + 24 = 36
The student passes 36 quizzes out of 50.
We convert this to a percentage
%
Answer:
2/3 + 2/3 + 1/3.
Step-by-step explanation:
You can use equivalent fractions. 6 is 2x more than <u>3</u>. You can use three as the denominator.
Answer:
101.7 ft I think
Step-by-step explanation:
5 1/3 times 2 is 10.7
4 3/4 time 2 is 9.5
10.7 times 9.5 is 101.65
The six becomes a 7 to make 101.7
5/5 is 1/1 but the simplest form is just 1
the equation that we can solve using the given system of equations is:
3x^5 - 4x^4 - 11x^3 + 2x^2 - 10x + 15 = 0
<h3>Which equation can be solved using the given system of equations?</h3>
Here we have the system of equations:
y = 3x^5 - 5x^3 + 2x^2 - 10x + 4
y = 4x^4 + 6x^3 - 11
Notice that both x and y should represent the same thing in both equations, then we could write:
3x^5 - 5x^3 + 2x^2 - 10x + 4 = y = 4x^4 + 6x^3 - 11
If we remove the middle part, we get:
3x^5 - 5x^3 + 2x^2 - 10x + 4 = 4x^4 + 6x^3 - 11
Now, this is an equation that only depends on x.
We can simplify it to get:
3x^5 - 4x^4 - 11x^3 + 2x^2 - 10x + 15 = 0
That is the equation that we can solve using the given system of equations.
