Answer:
C. -26=x
Step-by-step explanation:
3(3x-2)=5(2x+4)
9x-6=10x+20
9x-10x=20+6
-x=26
-x/-1=26/-1
x= -26

To find
, Beau found
and
. He said that since 5 is between 4 and 9,
, is between 2 and 3. Beau thinks a good estimate for
, is
Is his estimate high or low? How do you know?
Answer:
The estimation is high because 5 is very close to 4 so
will also be very close to
which is lower than the estimate
In order to get a good estimate
The first step is to choose a number between 2 and 3 let say 2.8 , 2,85 , 2.9 and the square them
i.e



From here we can see that
lies between 2.2 and 2.3 but is closer to 2.2
So a good estimate for
is 2.2

Answer: I got -6a + 48
Step-by-step explanation:I distributed and I got negative 6a because when you distributed the variable goes with whatever number is before it and I got 48 because -6 multiplied by 8 you get positive 48 because the 8 is bigger then the negative 6 so I don't know if your teacher wants you to solve for the answer but like I said I got -6a + 48
Answer:
T-.5 = x (200)
Step-by-step explanation:
Let T = total time in hours
30 mn = .5 hours 30
/60
=
.5
$ 2.00 is the rate per hour.
so T
−
.5
= the time that will be charged at the rate
Therefore the total charge is then
T
−
.5
