Two decimals are 0.34, 0.83, and 0.83 and Holland could have used it to make a sum of 2.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
We get x + x = 2x by using x to signify our missing values and the assumption that there are two missing values. We obtain the equation 2x + 0.34 since it is the product of these integers and 0.34; after setting it equal to 2, 2x + 0.34 equals 2.
First, take 0.34 off both sides to get 2x = 1.66. To get x = 0.83, divide both sides by 2 now.
Therefore, the decimals are 0.34, 0.83, and 0.83.

There is a proportional relationship between the amount of dark chocolate (in ounces), x, and the amount of almonds (in ounces), y, in each package of Sweet and Salty trail mix.
x (ounces of dark chocolate) 2 y (ounces of almonds) 8
Answer:
y = 4x
Step-by-step explanation:
You want an equation that represents the proportional relationship between ounces of chocolate (x) and ounces of almonds (y) when we know (x, y) = (2, 8).
Proportional relationA proportional relation can be written using the equation ...
y = kx
where k is a constant.
The value of k can be found if a pair of values is known for x and y.
k = y/x . . . divide by x
k = 8/2 = 4 . . . . use (x, y) = (2, 8) from the table.
The equation for the relationship is ...
y = 4x
The proportional relationship that accounts between the amount of dark chocolate and the amount of almonds is y = 4x.
What is ratio and proportion?
Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. An equation known as proportion shows that the two ratios presented are equal to one another. A ratio is the comparative or condensed form of two quantities of the same type. We may determine how many times one quantity is equal to another using this relationship. The ratio can be defined as the number that can be used to represent one quantity as a percentage of another.
Given, for 2 ounces of dark chocolate(x), 8 ounces of almonds(y) are put in.
Taking the ratio as y to x, we have:
y/x = 8/2 ⇒ y/x = 4 ⇒ y = 4x
Thus, the proportional relationship that accounts between the amount of dark chocolate and the amount of almonds in each package of Sweet and Salty trail mix is y = 4x.

What are mathematics operations?
An operation is a function in mathematics that converts zero or more input values (also known as "operands" or "arguments") to a well-defined output value.The operation's arity is determined by the number of operands.Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the most commonly studied operations.A zero-arity operation, also known as a nullary operation, is a constant.The mixed product is an example of an arity 3 operation, also known as a ternary operation.Amy has 4 pounds of ground beef to make meatballs and he uses 3/8 pound per meatball to make 9 meatballs
We have to subtract 3/8 from 4
= 4 - 3/8
= 29/8
There are 29/8 pounds of ground beef left
Therefore the number of 1/8 pound meatball that can be produced from 29/8 pounds of ground beef can be calculated as follows;

Answer:
39/15
Step-by-step explanation:
-4/5+-1/3+1 2/5+7/3
Convert all to fractions having the least common denominator. The mixed denominators of 3 and 5 could be converted to denominators of 15, thereby allowing them to be numerically combined.
-4/5+-1/3+1 2/5+7/3
(-4/5)(3/3) = -12/15
(-1/3)(5/5) = -5/15
(+1 2/5) = (5/5 + 2/5) = (7/5)(3/3) = 21/15
(7/3)(5/5) = 35/15
Since we have a common denominator (15) we can now sum the individual fractions by adding their numerators:
-12 -5 + 21 + 35 = 39
Now add back the denominator
The result is 39/15

Answer:
Step-by-step explanation:
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y and an x-intercept is a point where the graph of a function or relation intersects with the x-axis of the coordinate system. To find the x-intercept we set y = 0 and solve the equation for x. This is because when y=0 the line crosses the x-axis. When an equation is not in y = mx + b form, we can solve for the intercepts by plugging in 0 as needed and solving for the remaining variable. For example In algebra, 2-dimensional coordinate graphs have a horizontal axis, or x-axis, and a vertical axis, or y-axis. The places where lines representing a range of values cross these axes are called intercepts. The y-intercept is the place where the line crosses the y-axis and the x-intercept where the line crosses the x-axis. For simple problems, it is easy to find the x-intercept by looking at a graph. You can find the exact point of the intercept by solving algebraically using the equation of the line.

homeowner makes the trough from a rectangular piece of of aluminum that is 20 in. long and 12
in. wide. He makes a fold along the long sides a distance of x inches from the edge. If he wants the
trough to hold 360 in³ of water, how far from the edge should he make the fold?
Answer:20 in * (12 in - 2X in) * (X in) = 360 in3
This can be simplified by dividing both sides by 20 in:
20 in * (12 in - 2X in) * (X in) = (360 in3/ 20 in)
After dividing both sides by 20 in:
(12 in - 2X in) * X in = 18 in2
Distribute X in. across (12 in -2X in):
12X in2 - 2X2 in2 = 18 in2
1.Subtract 18 in2 from both sides:
12X in2 - 2X2 in2 - 18 in2 = 0
2. Rearrange the equation:
-2X2 in2 + 12X in2 - 18 in2 = 0

Round to 1 significant figure
What is Rounding?
To estimate a certain number in a context, rounding is a process. Look at the next digit in the correct position to determine how to round a number; if it is less than 5, round down, and if it is 5 or more, round up. The term "rounding decimals" describes the accurate rounding of decimal figures.
How to round a figure
It rounds to the most important figure in the number. To round to a significant figure: look at the first non-zero digit if rounding to one significant figure. look at the digit after the first non-zero digit if rounding to two significant figures.
To understand this term lets take and example:
24982 correct to 1 significant figure
If we round up, then the answer is
30,000
but if we were to round down, the answer would be
20,000;
If we want to determine which one is correct, we have to look at the second digit of the original number, which is
4
Since the second digit is less than 5
we can round down, so the answer would have to be
20,000
Hence, 24982 round to 1 significant figure is 20,000
