Answer:
0.83
Step-by-step explanation:
The 3 keeps going on and on and on :)
A - 2b = 2 . . . (1)
a + b = 2(b + 3)
a + b = 2b + 3
a - b = 3 . . . (2)
(1) - (2) => -b = -1 => b = 1
From (2): a - 1 = 3 => a = 3 + 1 = 4
Therefore, a = 4 and b = 1
First convert feet to inches:
18 ft × (12in/1ft)= 216 in
15 ft × (12 in/1ft)= 180 in
divide each side of the room by 9 inches to get number of white tiles per a wall
wall 1(18ft): 216in/9in= 24 white tiles
wall 2(15ft): 180in/9in= 20 white tiles
wall 3(18ft): 216in/9in= 24 white tiles
wall 4(15ft): 180in/9in= 20 white tiles
Lastly, add up all the white tiles and subtract 4 (the tiles that we counted twice because they were the corner tiles and touched both walls)
24+20+24+20-4= 84 white tiles total
Answer:
x=12
Step-by-step explanation:
height of tree)/(shadow length of tree) = (height of pole)/(shadow length of pole)
x/26 = 6/13
13x = 26*6
13x = 156
x = 156/13
x = 12
(hope this helps can i plz have brainlist :D hehe)
Answer:
X = 37
Step-by-step explanation:
Polygon = 360 Degrees
(x+9)+(2x)+(x-1)+(3x)+(x)+(x+19)=360 [Solve for x]
