B^-2/ab^-3 = b^-2/b^-3 x 1/a = b^[-2-(-3)] x 1/a = b x 1/a = b/a
X² = Side1² + Side2² - 2[(Side1)(Side2)] cos(Toby's Angle)x² = 55² + 65² - 2[(55)(65)] cos(110°)x² = 3025 + 4225 -7150[cos(110°)]x² = 7250 - 2445.44x = √4804.56x = 69.31m
∴The distance, x, between two landmarks is 69.31m

Answer:
x = -13
Step-by-step explanation:
Let the number be x. ATQ,

The above equation shows Three-fourths of the difference of a number and 7 is negative fifteen. We need to find the number.
cross multiplying both sides,

So, the number is -13.
The value of x is 1
Explanation:
The equation is 
Subtracting both sides by 3, we get,

Taking log on both sides, we get,

Rewriting the equation by 
Thus, we have,

Applying log rule, if
, then 
Thus, 
Substituting
in
, we get,

Also, since,
, then 
Thus, 
Hence, the value of x is 1
