Answer: 1000
Step-by-step explanation:
10xm×10cm=100cm
400cm×250cm=100000cm
100000cm²÷100cm²=1000
Answer:
[4m(2.5m)(100^2cm^2/m^2)]/10^2cm^2=1000 tiles
x = 7 ; y = 9
Given the system of equation :
y = 2x - 5 - - - (1)
-x + y = 2 ___(2)
From (1)
y = 2x - 5
Put y = 2x - 5 into (2)
-x + 2x - 5 = 2
-x + 2x = 2 + 5
x = 7
We can then solve for y;
Substituting x = 7 into. Equation (1)
y = 2(7) - 5
y = 14 - 5
y = 9
Hence ;
