Are you asking a question? If you're asking if the statement you made is true, yes that is correct.
5x + 10y = 18
x = y -6, we substitute this into first equation.
5x + 10y = 18
5*(y - 6) + 10y = 18
5y - 30 + 10y = 18
So it the last option from the top.
Hey how was ur day i hope u find this out
Answer:
240naira
Step-by-step explanation:
The board measures 2½m by 1¼m
The area of the board is;
2½× 1¼ = 5/2 × 5/4 = 25/8 m²;
But 25/8 m² cost 750 naira;
Therefore 1m² cost 750 / 25/8
750 × 8/25 =
30 × 8
