Answer:
2.0
Step-by-step explanation:
Subtract the smaller number from the larger to find their difference:
1.5 -(-0.5) = 2.0
The distance between the given values is 2.0.
Answer:
B) 16 . . . . the value of Z
Step-by-step explanation:
The problem statement tells us that ...
... x = y +12
... z = y - 8
Then x - z = (y +12) -(y -8) = 20.
In ratio units, we have ...
... x:z = 9:4
The difference of these in ratio units is 9-4 = 5, so each ratio unit must stand for 20/5 = 4 units of X, Y, or Z. Hence ...
... Z = 4·4
... Z = 16
_____
<em>Check by finding the other values</em>
... X = 9·4 = 36
... Y = X -12 = 24 = Z +8 . . . . yes

Answer:
x=1 or x=−2 or x=−3
Step-by-step explanation:
x3+4x2+x−6=0
Step 1: Factor left side of equation.
(x−1)(x+2)(x+3)=0
Step 2: Set factors equal to 0.
x−1=0 or x+2=0 or x+3=0
x=1 or x=−2 or x=−3
