Answer:

Constant of variation: 1/4

Slope of the line: 1/4

Step-by-step explanation:

The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.

The slope formula states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".

Maria is 8 years older than her brother, and the sum of their ages is 72 years. How old is her brother?

Maria's brother is 32 years old.

Let's assume that:

As per the provided information, Maria is 8 years older than her brother, so her age can be expressed as [tex]\large\rm{x+8}[/tex].

The sum of their ages is 72 years, so we can set up the equation:

[tex]\Large\begin{aligned}\rm{x + (x+8)}& =\rm{72}\end{aligned}[/tex]

Substitute Maria's age into the above equation and solve for x:

[tex]\Large\begin{aligned}\rm{x + (x+8)}& =\rm{72}\\\rm{2x + 8}&=\rm{72}\\\rm{2x + \cancel{8 \red{-8}}}&=\rm{72 \red{-8}}\\\rm{2x}&=\rm{64}\\\rm{\dfrac{\cancel{2}x}{\cancel{\red{2}}}}&=\rm{\dfrac{64}{\red{2}}}\\\rm{x}&=\bold{32}\end{aligned}[/tex]

[tex]\therefore[/tex] Maria's brother is 32 years old.

To check our answer, we can substitute [tex]\large\rm{x = 32}[/tex] into the equation [tex]\large\rm{x + (x+8) = 72}[/tex]:

[tex]\Large\begin{aligned}\rm{x + (x + 8)}&=\rm{72}\\\rm{\red{32} + (\red{32}+8)} &=\rm{72}\\\rm{32 + 40}&=\rm{72}\\\rm{72}&=\rm{72}\end{aligned}[/tex]

This is true, so our assumption that Maria's brother's age is 32 is correct.

Answer:

Maria's brother is 32 years old.

Step-by-step explanation:

Let's denote Maria's brother's age as [tex]\bf{x}[/tex]. Since Maria is 8 years older than her brother, her age can be represented as [tex]\bf{x + 8}[/tex]. The sum of their ages is 72, so we can write the equation:

[tex]\LARGE \boxed {\boxed{x + (x + 8) = 72}}[/tex]

Solving this equation, we get:

Now, we need to isolate [tex]x[/tex]. First, we can subtract 8 from both sides:

Next, we can divide both sides by 2:

So, Maria's brother is 32 years old.

Step-by-step explanation:

Look at the number and the angles

Multiple the angles all together that's how u find x

Answer:

The answer for number one is X=37. This is because 37 is half of 74.

Basically, these are all equal angles. The ones across from eachother are, and the angles that are right next to eachother are always going to equal 180, or half of 360. Number 4 is the same as the rest, but it seems more confusing because of the 5th line. If you add 55 and 85, then divide it by 8, you will get the answer.

This is pretty easy so this is it

Answer: Justin  dirty laundry was  reduced by 74. 18%

Step-by-step explanation:

Step 1

Total amount of clothes = 124 pieces

 Number of clothes reduced to = 32 pieces

To find the amount of the reduction, We will first Subtract the  number reduced to from the initial amount of clothes  giving us

Amount of reduction =  124- 32 =92 pieces of clothes

Step 2---Then we Divide the amount of the reduction of the clothes  by the total amount of clothes  to find the rate of reduction, giving us

Rate of reduction =  92/124 = 0.741

Step 3--- we finally Multiply the rate of reduction of clothes by 100 to find the percentage reduction.

0.741 x  100 = 74. 18%

Answer:

The length of the third side is 75.

Step-by-step explanation:

You have to use pythagorean theorem to solve this problem.  The pythagorean theorem is:  a² + b² = c².

In this case, the third side is equal to c.  Side c is always opposite of the right  angle.  It doesn't matter whether 60 or 45 is a or b because you are going to add them together anyways.

60² + 45² = c²

c² = 5625

c = 75 ...... You get 75 by taking the square root of 5625.

Hey there!

ax = 6

Divide both of your sides by “a”

ax/a = 6/a

Cancel out: a/a because that gives you 1 (or you can say)

Keep: 6/a because it is our value of x

Thus, your answer is mostly likely: x = 6/a

Answer:

0.98g+ 0.02m= 7.1224 gallons standard mixture

0.96g+ 0.04m= 6.25 gallons break oil

3.92 gallons of gasoline  is required for  4 gallons the standard mixture

Step-by-step explanation:

If we have to use 6 gallons of gasoline this means that 98%= 6 gallons and 2% would be 6/98*2

Gasoline: Motor oil

6              :    x

98        : 2

Using the product rule

x= 6*2/98= 0.1224 gallons of motor oil is required.

Let the gasoline be represented by g and motor oil by m then for the standard oil the equation would be

0.98g+ 0.02m= 7.1224 gallons standard mixture

For break in oil

Gasoline: Motor oil

6              :    x

96        : 4

Using the product rule

x= 6*4/96= 0.25 gallons of motor oil is required.

Let the gasoline be represented by g and motor oil by m then for the break oil the equation would be

0.96g+ 0.04m= 6.25 gallons break oil

Part b. For  4 gallons of the "break in" mixture

96% of the 4 gallons of the "break in" mixture is gasoline =  3.84 gallons of gasoline

4% of 4 = 0.16 gallons of motor oil

Now the standard mixture 4 gallons would contain 98 % of gasoline and 2 % of motor oil

98% of 4 gallons= 3.92 gallons of gasoline

2% of  4 gallons= 0.08 gallons of motor oil.

With 6 gallons of gasoline you could obtain 6.12 gallons of standard mixture or 6.25 gallons of break in mixture. In turn, if 4 gallons of break in mixture were prepared, there would be 2.16 gallons of gasoline left to prepare standard mixture.

Since the standard gasoline and oil mixture is about 98% gasoline and about 2% motor oil, and the "break in" mixture for a new engine is about 96% gasoline and about 4% motor oil, to determine the possible combinations of each kind of mixture you can prepare using 6 gallons of gasoline and, if you prepare 4 gallons of the "break in" mixture, how much gasoline will you have for the standard mixture, the following calculations should be performed:

A)

Therefore, with 6 gallons of gasoline you could obtain 6.12 gallons of standard mixture or 6.25 gallons of break in mixture.

B)

Therefore, if 4 gallons of break in mixture were prepared, there would be 2.16 gallons of gasoline left to prepare standard mixture.
