What is the length of AC ?
Lelechka [254]
Triangles ABC and CDE and similar with ABC being dilated larger. This means we can use ratios to help solve for x, and then solve fo AC.

\frac{84}{156-x} =  \frac{7}{x}
\frac{84x}{156-x} = 7
84x = 7(156 - x)
84x = 1092 - 7x
91x = 1092
x = 12
So, from this problem we now know that x is equal to 12. We merely need to plug that into what is given for AC and solve for AC.
AC = 156 - 12
AC = 144
Therefore, A is equal to 144.

Rearrange the equation so u is the independent variable. -12u+13=8w-3 <br><br> w= ___
Rama09 [41]

Answer:

w = \frac{-12u+16}{8}

Step-by-step explanation:

Reverse the equation placing w on the left side

8w - 3 = - 12u + 13 ( add 3 to both sides )

8w = - 12u + 16 ( divide both sides by 8 )

w = \frac{-12u+16}{8}
