5x-6y=10
This is a linear equation...
A typical linear equation is written in the form
y=mx+c
Where m=gradient
And c=intercept
So all you have to do is to express y in terms of x "make y the subject of the formula"
Therefore 5x-6y=10
6y=5x-10
Divide through by 6
6y/6 = 5x/6 - 10/6
The intercept here is = - 10/6
Gradient = 5/6-----the coefficient of x....
Hope this helped.....???
Hello !!
So first, you do cross multiplying:
50x = 14×7500
50x = 105000
----- --------
50 50
x = 2100
Hope this helps and have a beautiful day, my friend!!!
Cycling = 69 - (32 + 27) = 69 -59 = 10
Badminton = 62 - (32+28) = 62 - 60 =2
Archery = 63 - (27 + 28) = 63 - 55 = 8
Total for 1 sport = 10 + 2 + 8 = 20
Pupils left = 120 - 20 = 100
Pupils that picked two sports = 27 + 28 + 32 = 87
Number of pupils to pick all sports = 100 - 87 = 13
13 pupils picked all three
I think it’s 82 because 78+4=82
