Step-by-step explanation:
Hey. Let me help you on this one.
Let's break this problem down so it's easier for us to comprehend it.
There are 850 students in the school, and the amount of female students equals to the amount of male students + sixty additional females.
Amount of students in school = 850 students
Male students =
![X](https://tex.z-dn.net/?f=X)
Female students =
![X+60](https://tex.z-dn.net/?f=X%2B60)
Let's form an equation so we can work with what we have.
![X+(X+60)=850](https://tex.z-dn.net/?f=X%2B%28X%2B60%29%3D850)
Subtract 60 from both sides.
![X+X=790](https://tex.z-dn.net/?f=X%2BX%3D790)
Simplify
![2X=790](https://tex.z-dn.net/?f=2X%3D790)
Divide both sides by 2.
![X=395](https://tex.z-dn.net/?f=X%3D395)
Answer: There are 395 male students, and 455 female students.
Answer:
£910
Step-by-step explanation:
let 3x and 7x be the initial amounts in their accounts, then after alterations
Terry has 3x + 220
Faye has 7x - 300
After these changes the amounts are equal, hence
7x - 300 = 3x + 220 ( subtract 3x from both sides )
4x - 300 = 220 ( add 300 to both sides )
4x = 520 ( divide both sides by 4 )
x = 130
Faye initially had 7 × £130 = £910 in her account
