I don't think you finished the ? but what i see the answer is 3/x
The 3 angles of a triangle add up to 180 degrees so:-
10x - 10 + 10x + 8 + 8x = 180
28x = 180 + 10 - 8
28x = 182
x = 6.5 (answer)
Answer:
$5
Step-by-step explanation:
48/12=4
1.25x4=5
Or you could set it up as a proportion
12/1.25=48/x
Answer: 225 tiles
Step-by-step explanation:
Side of tile = 20 cm = 0.2 m
Side of bathroom = 3 m
Area of tile = 0.04 m²
Area of bathroom = 9 m²
No. of tiles = Ar (bathroom) / Ar (tile)
= 9 / 0.04
= 9 x 25
= 225 tiles
Step-by-step explanation:
x2+y2+6y+(9-9)=7
x2+y2+6y+9=16
x2+(y+3)2=16
