Answer:
r=201
d = 77 1/2
Step-by-step explanation:
6) First multiply left and right by 16, to get rid of the fraction:
r - 25 = 11*16
Now add 25 left and right:
r = 11*16 + 25 = 201
7) Add 5 left and right
2/5 d = 31
multiply by 5/2
d = 31 * 5/2 = 77 1/2
Answer:
2)

collect like terms

move the constant to the right hand side and change its sign.

Subtract the numbers

Divide both sides of the equation by 8

Answer:
there is not a complete question here ...
is not in a denominator to rationalize
if it were you would multiply the rational expression (the fraction)
by
the result (in the denominator would end up being "2 -1"
which is 1
Step-by-step explanation:
Answer:
18/(10-7)+2=8
(48/2)-4^2 +2*2=12
I hope you have a nice day!
