Answer:
The operation would be marked as undefined
Step-by-step explanation:
Many people don't feel comfortable using negative numbers so find the absolute values of both numbers.
|-10| = |-20| to 10 = 20
Since 10 is not equal to 20, it is undefined
-----------------------------------------------------------------------------------------------------------------
Just in case
If you meant (-10)x = (-20) Then do this:
-10x = -20
/-10 /-10 Divide by -10 do get x
A negative divided by a negative makes the answer positive.
-20/-10 = 2
x = 2
AB=10
The triangles are proportional. DC*2=AC. 12*2=24.
So DE*2=AB. 5*2=10
153.8 = 3.14r^2
Divide each side by 3.14 to get r alone.
48.9 = r^2
Take the square root of each side to isolate r.
r = 6.999
r= 7
Answer:
<h3>Convert the mixed number 247 2 4 7 into an improper fraction first by multiplying the denominator (7) by the whole number part (2) and add the numerator (4) to get the new numerator. Place the new numerator (18) over the old denominator (7) .</h3>
