To solve this polynomial equation, we first factor the left side.
To factor x² + 8x + 12 = 0, look for factors of 12 that add to 8.
These factors are 6 and 2 so we have (x + 6)(x + 2) = 0.
So either x + 6 = 0 or x + 2 = 0 and solving for
x in each equation, our answer is {-6, -2}.
22%=.20
50*.20=11
mark=(+) number (adding)
50+11=61
ans:61
hope it help u:)
Answer:
Step-by-step explanation:
The ratios of the numbers shown in the table are all ...
y/x = 16/4 = 20/5 = 4
Then the missing y-value is ...
y = 4x
y = 4(2) = 8
__
And the missing x-value is ...
36 = 4x
36/4 = x = 9
_____
<em>Additional comment</em>
The x- and y-values in a "ratio table" are proportional to each other. That means the y corresponding to half an x-value will be half the y-value. In other words, the y for x=2 will be half the y for x=4, or 16/2 = 8.
Also, the values add. We notice that y=36 is the sum of y=16 and y=20. This means the corresponding x-value for y=36 will be the sum of x=4 and x=5, or x = 4+5 = 9.
Answer:
50 employees
Step-by-step explanation:
We can set up a proportion which would be
4/x = 8/100
This shows 4 out of x people is the same as 8% of 100.
We divide 100 by 8, and then multiply by 4 to get 50.
We can check this by plugging 50 into the proportion.
4/50 = 0.08
8/100= 0.08
There are 50 total employees at the shop.
Answer:
n=3.75
Step-by-step explanation:
6-4n=9
4n=9+6
4n=15 /4
n=3.75
