This is the symmetric property of equality, and in a more general form it can be written as: if a=b then b=a.
<span>This is not to be confused with communicative property, which says that the order doesn't matter in some operations, such as addition, and can be written as a+b=b+a</span>
I cant see ur attached thing
We know that the area of a rectangle can be written as: length x width
so:
l x (1/5) = 9/20
9/20 x 5/1 = 45/20, which can be reduced to 9/4
So the length is 9/4 miles
Answer:
Step-by-step explanation:
<u><em># 21.</em></u>
÷ ( - 0.35 ) = - ÷ = - ÷ = - × = - <em>(B).</em>
<u><em># 22.</em></u>
( - ) ÷ ( - 2.5 )
= = 3.5
= = = 9.75
( 3.5 - 9.75 ) ÷ ( - 2.5 ) = ( - 6.25 ) ÷ ( - 2.5 ) = 2.5 <em>(D).</em>
75/25= 3
72/24= 3
7*3= 21
x= 21
I hope this helps!
