AC side and BC side have the same length because ΔCDA and ΔCDE are congruent.
The equation will be
AC = BC
Solve the equation
AC = BC
2x = 3x - 10
2x - 3x = -10
-x = -10
x = 10
The value of x is 10
Answer:
a = 20, b = 5
Step-by-step explanation:
| x-a| ≥ b
| x - 20 | ≥ 5
a = 20 ... car speed
b = 5 ... either 5 m/h above or lower than the limit speed 20 m/h
Answer:
D

becuase the -3 is going threw the dots
Answer:
The probability of receiving reimbursement within 42 days of filing is 0.8849 = 88.49%
Step-by-step explanation:
Let 
the probability of being reimbursed in an interval of a to b days, we want 
First, standardize x by doing the change
where 
is the mean of our original distribution and 
the standard deviation. So
This change transforms the original distribution in a normal distribution N(0,1) with mean 0 and standard deviation 1.
This is done in order to easily compute the area under the normal curve.
Since,
we then have
And we want the area under the normal curve between -7.2 and 1.2. This can be done either by using a table or a computer, and we find this area is 0.8849,
Hence, the probability of receiving reimbursement within 42 days of filing is 0.8849 = 88.49%
Answer:
x=-5
Step-by-step explanation:
Set up the rational expression with the same denominator over the entire equation.
2x-2/6=3x+3/6
Since the expression on each side of the equation has the same denominator, the numerators must be equal.
2x−2=3x+3
Move all terms containing x to the left side of the equation.
−x−2=3
Move all terms not containing x to the right side of the equation.
-x=5
Multiply each term in x=−5 by −1
x=−5
