Ustin weighs 15 pounds less than greg weighs. half of greg's weight is 75 pounds less than justin's weight. how much does each of them weigh? a. greg weighs 200 pounds, and justin weighs 185 pounds. b. greg weighs 190 pounds, and justin weighs 175 pounds. c. greg weighs 180 pounds, and justin weighs 165 pounds. d. greg weighs 170 pounds, and justin weighs 155 pounds.
option b. 1.93, -11.93 is the right answer.
here the given equation is x²-23 = 10x and we have to solve the equation for the value of x.
first we simplify the equation to bring in the shape of ax²+bx+c=0
x²-23 = 10x
(x²-23)-10x = 10x-10x
x²-10x -23 = 0
now we the formula for the value of
now x = (-5+6.93) = 1.93
and x = (-5-6.93) = -11.93
the correct answer is 8. but in the option there is no option with answer 8
the given expression is,
x - 9 = -6 + 5
rhs = -6 + 5 = -1
lhs = x -9
lhs = rhs
therefore x - 9 = -1
x = -1 + 9 = 8
therefore the correct answer is 8.
there is no option with correct answer. so we cant
the mean is the average of all numbers and is sometimes called the arithmetic mean.
in the data center, means and medians are often tracked over time to spot trends, which inform capacity planning or power cost predictions.the statistical median is the middle number in a sequence of numbers. to find the median, organize each number in order by size; the number in the middle is the median.
the mode is the number that occurs most often within a set of numbers.
the range is the difference between the highest and lowest values within a set of numbers.
area = 1/2 * sum of the parallel lines * height
= 1/2 * (3+8+3+8) * 12
= 1/2 * 22 * 12
= 132 in^2.
