Answer:

Step-by-step explanation:
Let that number be
. We can build an equation, and solve for
.
less than half of
is
.
more than
is
.
We are given that the two quantities are equal, so we have that
.
Adding
to both sides gives
.
Multiplying both sides by
gives
.
Subtracting
from both sides gives
.
Multiplying both sides by
gives
.
So, the number is
and we're done!
The check is left as an exercise to the reader.
Answer:
Her first error was adding the wrong number to both sides. Instead of 4², it should be 2²
Step-by-step explanation:
When completing the square, the number that needs to be added to both sides is (b/2)²
In this problem, b is 4. So, Carly should have added 2² to both sides, but she added 4² instead.
So, her first error was adding 4² to both sides instead of 2²
Increases I’m sure if it’s not right let me know because I think it is if not it’s c
Answer: 1/3 x + -1
Step-by-step explanation:
X f πxf
-1 2 -2
3 1 3
-1 -2 2
0 -3 0
total =3
mean (π)=πxf ÷n
= 3÷4
= 0.75 these is not answer I thank so
