The questions on the first section on a test value 3 points and the questions in the second section carries 5 points. if sydney answer 15 questions in the first section correctly what is the minimum number of questions she must have answered correctly in the second section.And the maximum points she scored is 80.
Answer:
Sydney must have answered at least 8 answers in the second section.
Concept
What is Inequality?
Inequality is a condition which compare algebraic expression using greater than(>), less than(<) symbols. It also shows values greater than equal to(≥), less than equal to(≤) and not equal to(≠) signs to solve the equation.
- let x represent the number of correct questions in the first section, and
- let y represent the number of correct questions in the second question.
Therefore the inequality representing her score is 3x + 5y > 80
Solution:
Following the inequality 3x+5y>80, 3x represents sydney's score in the first section which is equal to 3ₓ15 = 45
Now she needs to solve 8 questions in the second section to score
5 ₓ 8 = 40 for the inequality to be maintained.
i.e 3 ₓ 15 + 5 ₓ 8 > 80
45 + 40 > 80
85 > 80
If she solves 7 questions in the second section then the total score will be 45 + 45 ⊅ 80
Therefore sydney answers 8 questions correctly in the second section.

Hi there! :)
Answer:
y=50
*The answer must have a positive sign.*
Step-by-step explanation:
First, you switch sides.
Then, you subtract by 37 from both sides of an equation.
You subtract by the numbers from left to right.
Final answer is y=50
Hope this helps!
Thanks!

How do you solve this
Answers
6x=5x+7
subtract 5x form both sides
6x-5x=5x-5x+7
x(6-5)=x(5-5)+7
x(1)=x(0)+7
x=0+7
x=7
subsitute 7 for x
6(7)=y
42=y
x=7

the answer to your question is 0.14 recurring
to solve this problem you must first learn about indices when u have a number with x in the back of it you must times the number by how much it is and when u have a next alphabet across of the equal sign it is always 1 and if u divide 6 into 1 you will get 0.14 recurring

So the original:
y² - 5y + 2
becomes:
3² - 5×3 + 2.
which is:
9 - 15 + 2.
9 - 15 = -6
-6 + 2 = -4.
-4 is the answer.
