Add 2x to both sides,
3x+9=18
Subtract 9 from both sides. 3x=9
Divide both sides by 3.
x=3
Answer:
C
Step-by-step explanation:
We need to use the distance formula, which says that for two points 
and 
, the distance between them is:
d = 
Here, the two points are (-2.5, 4.5) and (4.75, 4.5), so:
d = 
= 7 1/4
The answer is C.
Triangles IJK and LMN are similar. Then, the proportion between their similar sides must be equal. That is:
IJ/ML = JK/MN = IK/LN
where:
IJ = x
JK = 54
IK = y
MN = 42
ML = 28
NL = 35
In order to find the value of y, you consider the equation JK/MN = IK/LN, and solve for y, just as follow
JK/MN = IK/LN replace by the values
54/42 = y/35 multiply both sides by 35
(54/42)(35) = y
45 = y
Hence, y = 45
