3/x-3+x/x+3
3(x+3)+x(x-3)/(x-3)(x+3)
3x+9+x^2-3x/(x-3)(x+3)
x^2+9/X^2-9
Answer:
I'm going to calculate with sides 28 m
4,900 tiles used
Step-by-step explanation:
Area restaurant 28x28 = 784 m squared
each tile 40 cm = 0.4m
area of tile 0.4x0.4 =0.16
784/0.16 = 4,900
Answer:
Kenyan French Roast coffee x=6
Sumatran coffee y=14
Step-by-step explanation:
x+y=20 blend coffee
8x+7y=7.3(20) selling price
x+y=20 ⇒ x=20-y
substitute in the equation:
8x+7y=7.3(20)
8(20-y)+7y=7.3(20) for 20 pound blend
160-8y+7y=146
-y=146-160
y=14 pond
x+y=20
x=20-14=6
check : 14*7+6(8)=146/7.3=20 pound
