So assuming that the total =27
r+b=27
r=-5+3b
r=3b-5
subsitute 3b-5 for r in first equation
3b-5+b=27
4b-5=27
add 5
4b=32
divide by 4
b=8
subsitute
b+r=27
8+r=27
subtracct 8
r=19
red=19
blue=8
P = 2(L + W)
P = 28
L = 2W - 1
28 = 2(2W - 1 + W)
28 = 2(3W - 1)
28 = 6W - 2
28 + 2 = 6W
30 = 6W
30/6 = W
5 = W ....width is 5 ft
L = 2W - 1
L = 2(5) - 1
L = 10 - 1
L = 9 <=== length is 9 ft
1. X=2+1/2y+1/2z
2. X=-1+2y+z
3. X=16/3-1/3y-1/3z
Answer:
8 piece shaded for the first one one
2 piece shaded for the second one
Step-by-step explanation:
You said 9/8 so 8 pieces shaded out of 9
You said 2/4 so 2 piece shaded out of 4
You should search it on youtube becouse pepople cant really explain or draw the shape to show you
