Answer:
L=2v/n -c n and -c is seperated.
Answer:
2(x-9) = 2
Step-by-step explanation:
Difference indicates subtraction:
The difference of a number and
9
is
(
x
−
9
)
Twice the difference means
2
(
x
−
9
)
We know that the answer to this is
2
, so as an equation:
2
(
x
−
9
)
=
2
If you solve it we would have:
x
−
9
=
1
←
÷
2
x
=
1
+
9
x
=
10
The difference between
10
and
9
is
1
and twice
1
is
2
.
The number is correct.
Note that written as:
The difference of twice a number and
9
would have a different expression. This would be
2
x
−
9
Answer:
Angle 2 is 36 degrees
Step-by-step explanation:
73 - 37 = 36
I believe it would be 50 pounds. if one ream is 5 pounds, you would multiply that by however many reams you have. so if you have 10 you do 5 • 10 which gives you 50
x+y = 47
x-y = 21
------------ add together
2x =68 divide by 2
x=34
x+y = 47
34+ y = 47
subtract 34 from each side
y = 13
the two numbers are 34 and 13
