The answer i got is 44/3 but as a mixed number it’s 14 2/3
If we multiply the first equation by 2 we get
2x - 4y = 12
but the second equation is
2x - 4y = 10
2x - 4y can't have 2 different values so the are no solutions
And isosceles triangle always equals 180 degrees so to find the value of x what number would you need for the value to be 180
The answer would be 2 over 3, or 2/3. (:
Answer: The number of girls in the auditorium is represented by the algebraic expression y=(4x +72) /5
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Number of boys added: 18
</em>
- <em>Ratio of boys to girls: 5:4
</em>
So, the total number of boys is:
x + 18
Number of girls = y
Number of boys / number of girls = 5/4
(x+18) /y = 5/4
Solving for "y"
4 (x +18) =5 y
4x +72 = 5y
(4x +72) /5 = y
The number of girls in the auditorium is represented by the algebraic expression y=(4x +72) /5
