DE + EF = 4x+2
DE = x+7
EF = 7
Substitute these in
x + 7 + 7 = 4x + 2
x + 14 = 4x + 2
subtract x from both sides
14 = 3x + 2
subtract 2 from both sides
3x = 12
divide both sides by 3
x = 4
substitute this in to find the length of DE
DE = x + 7
(4) + 7 = 11
the answer is 11
Y=-9x+10 is the equation solved for y.
Answer:
Step-by-step explanation:
4/1000=0.0004
200/10= 20
8/100=0.08
30/100=3
7/1000=0.0007
6/10=0.6
Answer:
Probability = 0.15%
Step-by-step explanation:
The provided information is:
Let X be the scores of the IQ scores that is normally distributed with mean and standard deviation
.
That is
So, 58 is 3 standard deviation left to the mean.
As 99.7% of probability lies within the three standard deviation.
Thus, above three standard deviation is:
Thus, the required probability is 0.15%
Hi there!
First of all simplify x+5(x-1)=(x-3)4-1.
This would make 6x-5=4x-13.
Next, subtract 4x from both sides.
6x-5-4x=4x-13-4x
2x-5=-13
Then add 5 to both sides.
2x-5+5=-13+5
2x=-8
Finally divide by 2 on both sides.
2x/2=-8/2
x=-4
Your answer is -4.
Hope this helped!
