Answer:
Step-by-step explanation:
Looking at the diagram,
Line DT is parallel to line line BM, therefore, triangle DHT is similar to triangle BHM. This means that
DH/DB = TH/MH
DH = 15 + 6 = 21
TH = 9 + x
Therefore
(9 + x)/21 = 9/6
Cross multiplying, it becomes
6(9 + x) = 21 × 9 = 189
54 + 6x = 189
Subtracting 54 from the left hand side and the right hand side of the equation, it becomes
6x + 54 - 54 = 189 - 54
6x = 135
Dividing the left hand side and the right hand side of the equation by 6, it becomes
6x/6 = 135/6
x = 22.5
Answer:
d
Step-by-step explanation:
by substitution what is before x² is considered as a
what is before x is b and the number alone(without x) with it's sign included is c
Answer:
y = -948
Step-by-step explanation:
y/-12 + 16 = 95 (subtract 16 from both sides)
y/-12 = 79 (multiply -12 to both sides)
y = -948
It's true and true and false
