Answer:
x=−5
Step-by-step explanation:
Step 1: Subtract 5x from both sides.
−4x+10−5x=5x+55−5x
−9x+10=55
Step 2: Subtract 10 from both sides.
−9x+10−10=55−10
−9x=45
Step 3: Divide both sides by -9.
−9x
−9
=
45
−9
x=−5
Answer:
x=−5
Answer:
D. X + 9
Step-by-step explanation:
x² + 2x - 63
What 2 numbers multiply to -63 and add to 2
9 * -7 = -63
9+-7 = 2
(x+9)(x-7)
We know that
<span>8 machines in the factory could make all the bottles in 5 days
so
100%-----------> 5 days
1 day------------> 100%/5------> 20% with 8 machines
1 machine work at the rate-------> 20%/8-----> 2.5% per day
day 1---------> </span><span>4 machines are used to make the bottles-----> 4*2.5%---> 10%
</span>day 2--------> 4 machines are used to make the bottles-----> 4*2.5%---> 10%
day 3-------->8 machines are used to make the bottles-----> 8*2.5%---> 20%
day 4-------->8 machines are used to make the bottles-----> 8*2.5%---> 20%
day 5-------->8 machines are used to make the bottles-----> 8*2.5%---> 20%
day 6-------->8 machines are used to make the bottles-----> 8*2.5%---> 20%
<span>total work in 6 days=[10+10+20+20+20+20]------> 100%
the answer is
6 days

Answer:
The given Expression is sometimes true.
Step-by-step explanation:
from the question,
The given expression by Cary is 
.
So, solving the expression we get
⇒ 
Let 
is an integer.
Whenever,
(a) 
{ 
}
The given Expression always gives negative value.
(b) 
{
}
The given Expression always gives positive value.
Here, we get that the given Expression is not providing the Negative value always, that's why it is not always true and can't be never true.
Hence,
According to Cary's claimantion the given Expression is sometimes true.
