Answer:
Hey there,
(It would be good to note that i just learned how to simplify/solve algebraic expretions)
P=21+2w
P/21=2w
then we flip it
2w=p/21 which could also be
w=2(p/21) i think
Answer:

since 5.46 is equal to 5.5...
I think the answer is the first one
Answer:
-6/5
Step-by-step explanation:
solution;
let,the number be x,
product of <u>twice</u><u> </u><u>of</u><u> </u><u>x</u> and <u>six</u> = the <u>difference </u>
<u>difference of eleven times x and 6/5</u>
or, (2x×6)=(11×x)-(6/5)
or, 12x = 11x - 6/5
or, 12x - 11x = -6/5
therefore,x =-6/5
Therefore, the number required is (-6/5) whose product of twice a number and six is the same as the difference of eleven times the number and 6/5 .
This is hard to write... I hope this makes sense to you...
3x-2y=-39
x+3y= 31
We want to use elimination therefor, we need to either get our x or our y to add together to get zero.
To do this, we will multiply -3 to (x=3y=31)
NEW EQUATION
3x-2y=-39 PLUS
-3x-9y= -93 Equals
Answer: -11y= -54
y= 4.9
Plug in to solve for x (put new y in)
3x-2(4.9)=-39
x= -9.73
99.60 or 100.00? I haven’t done this for a longgggg time
