Answer:
b + g = 25
b = g + 3
Step-by-step explanation:
Let b = number of boys.
Let g = number of girls.
"Mrs. Smith has a total of 25 kids in her class."
b + g = 25
"There are 3 more boys than there are girls."
b = g + 3
The system of equations is:
b + g = 25
b = g + 3

Step-by-step explanation:
Answer:
The value of the variable 'b' is 3 and GH is 9
Step-by-step explanation:
Given:
![GI = 5b+1\\\\HI=4b-5\\ \\HI=7](https://tex.z-dn.net/?f=GI%20%3D%205b%2B1%5C%5C%5C%5CHI%3D4b-5%5C%5C%20%5C%5CHI%3D7)
H is between G and I
Such that G - H - I
To Find:
GH = ?
Solution:
On Substituting HI we get
![4b-5=7\\\\\therefore 4b=7+5=12\\\\b=\dfrac{12}{4}=3](https://tex.z-dn.net/?f=4b-5%3D7%5C%5C%5C%5C%5Ctherefore%204b%3D7%2B5%3D12%5C%5C%5C%5Cb%3D%5Cdfrac%7B12%7D%7B4%7D%3D3)
Substituting 'b' in HI and GI we get
![HI=4\times 3 -5=12-5=7\\\\\therefore HI = 7](https://tex.z-dn.net/?f=HI%3D4%5Ctimes%203%20-5%3D12-5%3D7%5C%5C%5C%5C%5Ctherefore%20HI%20%3D%207)
![GI=5\times 3 +1=15+1=16\\\\\therefore GI = 16](https://tex.z-dn.net/?f=GI%3D5%5Ctimes%203%20%2B1%3D15%2B1%3D16%5C%5C%5C%5C%5Ctherefore%20GI%20%3D%2016)
Now, by Line Addition Property we get
![GI=GH+HI](https://tex.z-dn.net/?f=GI%3DGH%2BHI)
Substituting 'HI' and 'GI' we get
![16=GH+7\\\\\therefore GH=16-7=9](https://tex.z-dn.net/?f=16%3DGH%2B7%5C%5C%5C%5C%5Ctherefore%20GH%3D16-7%3D9)
The value of the variable 'b' is 3 and GH is 9
