Answer:
x = 32
Step-by-step explanation:
The sum of all interior angles of this pentagon is 540
Solve for x by using this formula
540 = (180-71)+(180-85)+(180-44)+(180-3x)+(180-2x)
540 = 700 - 5x
540 - 700 = -5x
-160 = -5x
-160/-5 = x
32 = x
Answer: 1. [-8, 8]
2. [-27, 27]
Step-by-step explanation:
1. |X|≤8
x≤8 or x>=-8
-8<=x<=8 ==> [-8, 8]
2. |X|≤27
x≤27 or x>=-27
-27<=x<=27 ==> [-27, 27]
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)
3/8 is 0.375, which is bigger than 0.3, so 3/8 is larger.
