51/100 * 400 = 51/100 * 400/1 = 51/1 * 4/1
= 204
Solve this simultaneously.
Where a= apples and p= pears,
a+p=50 and 2a+3p=130
Multiply a+p=50 by 2 on both sides to get:
2a+2p=100
Then subtract the two equations from e...
3x2y5+5x3y4y'+3 = 24y2y'
3x2y5+3 = (24y2–5x3y4)y'
y' = (3x2y5NGAnswered by Nora G. • Maths tutor1700 Views
f(g(x))=2(cx+5)+c
fg(x)=2cx+10+c
2cx=6x
2c=6
c=3
10+c=d
d=13
Multiply whole equation by 2
6y + 4x = 12y - x
Take 6y from both sides
4x = 6y - x
Add x to both sides
5x = 6y
divid both sides by 5
x = 6/5(y)
