Answer: C. (8, 16, 4)
Step-by-step explanation:
Given the following:
Let:
Trucks = T ; Cars = C ; SUVs = S
T =0.5(C + S) - 2 - - - (1)
C = 2T - - - (2)
T + C + S = 28 - - - (3)
T = 0.5(2T + S) - 2
T = T + 0.5S - 2
0 = 0.5S - 2
0.5S = 2
S = 2/0.5
S = 4
From T + C + S = 28
C = 2 T ; S = 4
T + 2T + 4 = 28
3T = 28 - 4
3T = 24
T = 24/3
T = 8
From T + C + S = 28
8 + C + 4 = 28
12 + C = 28
C = 28 - 12
C = 16
Hence, (T, C, S) = (8, 16, 4)
There called Pararell Lines.
Let x be for unknown number. Let x be first number .
X+1 To be second number .x+2be third number. X+(x+1)+(x+2)=312.
Simplify to get 3x+3=312 . Subtract 3 from both sides 3x-3=312-3. Once you subtract get 3x=109.then divide 3 both sides . 3x/3=309/3. To get x= 103.
Now once you have that First number 103. Second number 103+1=104 . And third number 103+2=105. To check add them 103+104+105=312
