Answer:
20x = 55
Step-by-step explanation:
First you have to add 3x to both sides of 11-3x=x

Now that you have 11 = 4x you divide 4 on both sides 
11/4 = x
But you can't divide 11 by 4 unless you are looking for the decimal form of 11/4 which is 2.75
so now we take 11/4 or 2.75 depending on if you need your answer in fraction or as a decimal and replace that with x however both will equal the number 55
<span>the formula that I used would be
p = a √( 2 - 2 cos(A) ) = a √( 2 + 2 cos(B) )q = a √( 2 + 2 cos(A) ) = a √( 2 - 2 cos(B) )<span>p2 + q2 = 4a2
this would give us these measurements for the diagonals
p=9
q=15</span></span>
200+30 but its hard to understand what you are trying to say so please be more specific
Answer:
x=9
Step-by-step explanation:
2x+10=28
2x=18
x=9
41 and 9/11 - 27 1/3 is equal to 14and 6/33
Hope it helps!
Think about what I gave you!:D
