To solve for

You first need to find a common denominator.
To do so, you need to make both denominators 10 by multiplying the top and bottom of

by 5

=

Reduce by dividing both the top and bottom by 2
Your answer is
Maybe because you're finding the "difference" between the two numbers. We could also question why the answer to an addition problem is called sum.
Well, 'sum'body said that's what they should be called a long time ago, that's why we're using that term to call them now.
Answer:
6 x 10= 60
60/2=30
Answer is<u> 30</u> i think

Answer:
21.5cm
Step-by-step explanation:
41,572=4/3*pi*r^3
Work backwards to solve for r
neither
• Parallel lines have equal slopes
• The product of perpendicular slopes = - 1
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y =
x + 3 is in this form
with slope m = 
rearrange 20x + 12y = 12 into this form
subtract 20x from both sides
12y = - 20x + 12 ( divide all terms by 12 )
y = -
+ 1 ← in slope-intercept form
with slope m = - 
Neither of the conditions for parallel/ perpendicular slopes are met
Hence the lines are neither parallel/ perpendicular
