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
I got 20. 6 x 10^6/3 x 10^5 = 2 x 10^1 = 2 x 10 = 20
Answer:
Step-by-step explanation:
It means how many roots are there.
For example: The first one has no solution. But the second one has two solutions, 3 and 1.
Which means two x-values.
Hope this helps!
4m + 14 - 2m < 2 (m+7)
4m+14-2m<2m+4
4m-2m-2m<4-14
0<10
The answer simplified is 6
