How do you add a fraction?

First you have to check if they have common denominator. If so, add the numerators and keep the denominator. If Not, you have to find common denominator before added. After that,  check if your fraction need to be simplify.

Solve:

Least common multiplier of 10 and 5 is 10

[tex]\frac{3}{10}+\frac{2}{5}[/tex]

Since [tex]\frac{3}{10}[/tex] already have a denominator of 10 we keep it.

[tex]\frac{2}{5}=[/tex] [tex]\frac{2\times2}{5\times2}[/tex] [tex]=\frac{4}{10}[/tex]

Now we have;

[tex]\frac{3}{10}+\frac{4}{10}[/tex]

Apply fraction Rule which is; [tex]\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}[/tex]

[tex]=\frac{3+4}{10}[/tex]

3 + 4 = 7

[tex]=\frac{7}{10}[/tex]

Hence, [tex]\frac{3}{10}+\frac{2}{5}=\frac{7}{10}[/tex]

Answer:

M = (36.5-8)/5

[M = 5.7 miles/day]

Step-by-step explanation:

The goal is 36.5 miles.  The remaining miles needed to achieve this goal is reduced by the miles already ridden, 8 miles.

(36.5 - 8) = 28.5 miles remaining.

We are asked to find a value for M, which is the average number of miles Ian would have to ride to reach his goal.  By average, we can assume it is the average miles/days remaining.  The days remaining are 5, so we have:

(28.5 miles remaining)/5 days = 5.7 miles/day

An equation for M using these steps would be:

M = (36.5-8)/5

A 3:2 image ratio refers to the proportion of the width to the height of an image or screen. It means that for every 3 units of width, there are 2 units of height.

The aspect ratio 3:2 is commonly used in digital photography, particularly for DSLR cameras and some mirrorless cameras.

In photography, the 3:2 aspect ratio is considered a standard format, it's the same as the traditional 35mm film frame, it's also the same as the aspect ratio of most modern digital cameras. It allows photographers to capture a wide range of scenes and subjects, and it's also a good option for cropping and printing photos.

For example, if an image's resolution is 3000x2000 pixels, it means that it has a 3:2 aspect ratio. The width of the image is 3000 pixels and the height is 2000 pixels, so 3000/2000 = 3/2

It's worth noting that the aspect ratio of 3:2 is a compromise between the wider aspect ratio of 16:9, used for video and some photography, and the taller aspect ratio of 4:3, used for more traditional photography.

For the given equation of the line 2x + 3y = 6 , the slope = -2 /3,

the x-intercept = 3 and the y-intercept = 2.

As given in the question,

Given equation of the line is :

2x + 3y = 6

Standard equation of the line with slope 'm' and y -intercept = c

y = mx + c

Convert the given equation into standard form we get,

2x + 3y = 6

⇒ y = (-2/3)x + 6/3

⇒y = (-2/3)x + 2

Slope of the line = -2/3

y - intercept when x = 0

y = 2

x - intercept when y = 0

x = 3

The right angle, 99, 171, and 159 are four of the angles. It follows that the x and y angles, which are also equal, must both equal 201/2.

A place where two lines converge creates an angle. They are quantified in degrees and are denoted by the symbol °. Four essential types are reflex, acute, right, and obtuse angles. A circle has 360 degrees. One terminal exists when two rays (half-lines) are merged form an angle. The rays are referred to as the angle's sides, occasionally as its legs, and occasionally as its arms, while the latter is referred to as the angle's vertex. The place where all points of an angle converge is known as the vertex.

Answer: Yes, after 7 weeks, they will have the same amount of money

Step-by-step explanation: So let’s say Joyce will be equation 1, so it would be - T = 13 + 6x, where T represents the total money, and x represents the number of weeks. And let’s say Enrique will be equation 2, which will be - T = 80 - 5x, where once again, T represents the total money, and x represents the number of weeks.

So, let’s start going off numbers, we will start at 5 weeks, when we put that in, Joyce will have $43 and Enrique will have $65, so we know it will be more than 5 weeks, so let’s try 8 weeks, Joyce will have $61 and Enrique will have $40, so it’s below 8, so how about we try 7, at 7 weeks, Joyce will have $55, and Enrique will have $55 too. So this means, after 7 weeks, Joyce and Enrique will have the same amount of money

Step-by-step explanation:

1.y = x * (1-0.4)

2.y = x - 0.4x

3.x = y / (1-0.4)

4.x = y + 0.4y

The equation 1 and 2 correctly represent the situation. In the first equation, we are multiplying the initial amount of water (x) with (1-0.4) which is the percentage of the water that is remaining after drinking 40% of it. In the second equation, we are subtracting 0.4x from x, which is equivalent to multiplying x by (1-0.4).

The equation 3 and 4 are not correct, as they are trying to calculate the initial amount of water from the remaining amount, but it's not possible to know the initial amount once it has been consumed.

You have 0.6X amount water remaining.

The amount of water remaining in the water bottle is X minus 40%. This means that if you had X amount of water at start you now have 60% of X left.  That is, you have 0.6X amount of water remaining.

The angles are congruent and the ratios of sides are equal, then the polygons are similar.

What is the similarity of polygons?

The similarity of polygons refers to the relationship between two or more polygons in which the corresponding angles are congruent (equal in measure) and the corresponding side lengths are in proportion.

We have,

Polygon 1:

Opposite Sides 24 = 24, 12=12,

Angles = 90°

Polygon 1:

Opposite Sides 16 = 16, 8=8,

Angles = 90°

This means that if two polygons are similar, their corresponding angles will have the same measure, and their corresponding side lengths will be in the same ratio. In other words, the ratio of any pair of corresponding sides of similar polygons will be the same.

For example, two triangles are similar if the ratio of their corresponding sides is the same, and their corresponding angles are equal. Similarly, two quadrilaterals are similar if the ratio of their corresponding sides is the same and their corresponding angles are equal.

It's important to note that similarity is a stronger relationship than congruence, because in congruence all the sides and angles must have the same measure, while in similarity only the angles and ratios of sides are the same.

Additionally, the similarity of a polygon can be determined by measuring the angles of the polygon, and comparing the ratios of the corresponding sides.

If the angles are congruent and the ratios are equal, then the polygons are similar.

Hence, the angles are congruent and the ratios of sides are equal, then the polygons are similar.

From the question, we have the following parameters that can be used in our computation:

h(x) 0 –12 0 8 0

The x-intercepts are where y = 0

So, we have

x = -2, x = 1 and x = 3

The multiplicity is 1

So, we have

Solutions can be divided into supersaturated, unsaturated, and saturated solutions based on how well the solute dissolves in the solvent.

A homogeneous mixture with the major ingredients solute and solvent is referred to as a solution.

Solutions can be divided into supersaturated, unsaturated, and saturated solutions based on how well the solute dissolves in the solvent.

Supersaturated solution: The excess solute will crystallize quickly in a supersaturated solution because it contains a lot of solute at a temperature where it will be decreased.

Unsaturated solution: When a solvent can dissolve any more solute at a specific temperature, the solution is said to be unsaturated.

Saturated solution: A saturated solution is one in which a solvent can no longer dissolve any more solute at a particular temperature.

The inverse function of f(x) = (x - 5)/3 is f^-1(x) = 3x + 5.

Solution:

To find the inverse of a function, we need to switch the x and y variables, and then solve for y.

Starting with f(x) = (x - 5)/3, we can switch the x and y variables to get y = (x - 5)/3.

We can then solve for x by multiplying both sides by 3, giving us 3y = x - 5.

We can then add 5 to both sides to get 3y + 5 = x, which is the inverse of our original function.

Therefore, the inverse of f(x) = (x - 5)/3 is f^-1(x) = 3x + 5.
