Let x = number of miles, cost per mile = 93 cents = $0.93
Cost = 20.95 + 0.93*x
200.44 = 20.95 + 0.93x
0.93x + 20.95 = 200.44
0.93x = 200.44 - 20.95
0.93x = 179.49
x = 179.49/0.93
x = 193
He drove 193 miles.
Answer:
Andre's Method is the only one that works
Step-by-step explanation:
Noah's method won't work because he doesn't follow the order of operations. You can pull the the 9 out first you have to distribute the 2 first.
Elena's method doesn't work because to eliminate the 18 you must use the reverse operation it must be added not subtracted.
Andre's Method is the only one that works
Answer:
The center is at ( (-1, -2) and the radius is 5.
Step-by-step explanation:
X^2 + 2X + Y^2 + 4Y = 20
Complete the square on the x and y terms.
(x + 1)^2 -1 + (y + 2)^2 - 4 = 20
(x + 1)^2 + ( y + 2)^2 = 25 Comparing this with the standard form:
(x - h)^2 + (y - k)^2 = r^2
- the center is at ( (-1, -2) and thr radius is 5.

Answer: B. Accurate but not reliable
Step-by-step explanation:
An experiment is said to be "reliable" when it consistently gives the same answers when done repeatedly, when the experiment is carried out several times it gives the same result each times.
An experiment is said to be " accurate "
when it produce a correct result using the right procedure and method .
In this case the research assessing a new screening tools for early identification of prostate cancer, test result is "accurate but not reliable ", since the consistent test result was not accurate.
