Answer:
Step-by-step explanation:
1) group any number with an X together and rewrite answer (if there is a negative in front of a number always carry it with it when rearranging.)
10x-10x-6-2
2) lets solve the numbers with Xs together
10x+10x= 20x
3) now lets solve whole numbers
-6-2=-8
4) bring down the 20x and the -8/ rewrite problem with your solved numbers
20x-8
5) we have to have X alone so in order to get rid of the 20 in front of the X you must divide 20 by 20x,
20x/20 ( it cancel's out and now you're left with X)
X=-8
6) but whatever you do to one side of the equal sign you have to do to the other side so now you must divide -8/20 which will leave you with
Answer: X=-0.4 or -2/5
which of these probability values indicates an event that is certain to happen
-0.80
-0.60
0.50
1
0.50 and 1 probability values indicates an event that is certain to happen
An event that is certain to happen has a probability of 1. An event that cannot possibly happen has a probability of zero. If there is a chance that an event will happen, then its probability is between zero and 1.
Probability of an event can not be negative.
We can easily discard first two options i.e. -0.80 and -0.60 as they are negative values.
Last two options i.e., 0.5 and 1 are positive values and they also lies in the range from 0 to 1. We can say that these values are considerable.
Final answer: 0.50 and 1 probability values indicates an event that is certain to happen

5. The 50 snakes in the serpentarium include families of 10 vipers, 23 colubrids, 9 elapids, and 8 giant snakes.
Calculate the percent of each type of snake. Use the percent that you find and multiply each times 360° to
find the number of degrees for each sector.
I need help solving the percent and degree
Percent of vipers is 20% and its degree is 72 degrees.
Percent of colubrids is 46% and its degree is 165.60 degrees.
Percent of elapids is 18% and its degree is 64.80 degrees.
Percent of giant snakes is 16% and its degree is 57.60 degrees.
How we do calculate the percent and degree?The percent can be calculated as follows:
Percent of vipers = (Number of vipers / Total number of snakes) * 100 = (10 / 50) * 100 = 0.20 * 100 = 20%
Percent of colubrids = (Number of colubrids / Total number of snakes) * 100 = (23 / 50) * 100 = 0.46 * 100 = 46%
Percent of elapids = (Number of elapids / Total number of snakes) * 100 = (9 / 50) * 100 = 0.18 * 100 = 18%
Percent of giant snakes = (Number of giant snakes / Total number of snakes) * 100 = (8 / 50) * 100 = 0.16 * 100 = 16%
The degrees can be calculated as follows:
Degree of vipers = Percent of vipers * 360 = 20% * 360 = 72 degree
Degree of colubrids = Percent of colubrids * 360 = 46% * 360 = 165.60 degree
Degree of elapids = Percent of elapids* 360 = 18% * 360 = 64.80 degree
Degree of giant snakes = Percent of giant snakes * 360 = 16% * 360 = 57.60 degree

Answer:
C. 1889
Step-by-step explanation:
Given fixed weekly costs of $3778 and a variable cost per handle of $1, you want to know how many handles must be produced weekly for sale at $3 each to break even.
Contribution marginThe "contribution margin" of each handle is the difference between its variable cost and its selling price:
$3 -1 = $2
Break evenThe enterprise will break even when the sum of contribution margins is equal to the fixed costs. If h is the number of handles produced and sold, then to break even, we must have ...
2h = 3778
h = 1889
1889 handles must be molded weekly to break even.
__
Additional comment
You get the same result if you write the profit equation and solve for the number of handles that makes profit be zero.
profit = revenue -cost
0 = (3h) -(3778 +1h)
3778 = 2h . . . . . as above
1889 = h

Slope intercept form is y=mx+b
Where m is the slope
general form is ax+by+c=0
this means, 2 is b
3x-2y=-16
y=3/2x+8
Now
subtract ax from both sides
3x -2y-3x= -16-3x
-2y=-16-3x
Subtract C from both sides
-2y=-3x+-16
divide both sides by b
y=-3/-2 x -16/-2
the slope is given by -a/b and the y intercept is given by -c/b
simplify
y=3/2x+8

In linear equation, he travelled 6 kilometers .
What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.the tricycle fare for the first kilometer costs = 15.00
additional amount = 6.50
Anthony paid to the tricycle driver = , 47.50

In this given sum we are provided with the values of principal , rate of interest , and the number of years , we are asked to calculate the amount payable after 4 years that is the matured amount which is calculated with the addition of the principal amount and the simple interest. For that we had to first find out the amount of interest and then we need to add that with the principal amount to get the matured amount or the amount that is payable at the end of 4 years.
