Let the number be x.
2x-3=55
2x=55-3
2x=52
x=52/2
x=26
we know that
if two lines are perpendicular, then the product of their slopes is equal to minus one
so

Step 1
<u>Find the slope of the given line</u>
we have

Solve for y
Divide by
both sides


the slope of the given line is 
Step 2
<u>Find the slope of a line that is perpendicular to the given line</u>
we have



substitute the value of m1

therefore
<u>the answer is</u>
the slope is 
Answer:
9
Step-by-step explanation:
Substitute w = 3 into the expression
6w - 9
= 6(3) - 9
= 18 - 9
= 9
<span>circumference = 60*PI cm
If an arc is 140 degrees of the circle then its length =
</span>
<span>60*PI cm * (140 / 360)
arc length = 23.33333 cm
