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 = 21
Step-by-step explanation:
4 - 7x +10 = 15 - 6x - 8
-7x + 14 = -6x -7
14 + 7 = -6x + 7x
21 = x or x=21
Answer:
DC = DA Given
DB = BD Reflexive property
ΔDCB ≅ ΔDAB LH
∠DBC = ∠ABD = 20°
Hope this helps!
8 weeks because 2 1/2 plus 2 1/2 plus 3 is 8.
