Answer:
3x-x+2=4
Step-by-step explanation:
Number of boys = x
Number of girls = x plus 15% of x = 1.15x
Ratio of boys to girls x:1.15x = 1:1.15 = 20:23![\\](https://tex.z-dn.net/?f=%5C%5C)

Answer:
y =
x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m =
and c = 1 , thus
y =
x + 1 ← equation of line
Answer:
y = -2/5x - 3/5
Step-by-step explanation:
2x + 5y = -8
5y = -2x - 8
y = -2/5x - 8/5
y = -2/5x + b
-3 = -2/5(6) + b
-3 = -12/5 + b
-3/5
Answer: Original number of cow = 200
Mongo receive = 100 cow
Masuu receive = 75 cow
Muzo receive = 25 cow
Explanation:
Let x be the original number of cow:
And x = 100%
Mongo = x/2 = 100%/2 = 50%
Thus, mongo receive 50% of the cow and the other 50% are divide to masuu and muzo.
50% = 3/4 + 1/4
Where 3/4 was given to masuu and 1/4 was given muzo.
But muzo receive 25 cow as a remaining thus, 1/4 = 25
If 1/4 = 25 then 3/4 = 75
Therefore, 50% = (75 + 25)cow
50% = 100 cow
But Mongo receive half of the original cows. Which mean he receive 100 cows.
Original number of cow = 100 + 75 + 25 = 200 cows
