Completely simplify the rational expression LaTeX: \frac{7x}{3y} + \frac{12x}{9y}

Answers

Answer 1

Answer:

[tex]\frac{11x}{3y}[/tex]

Step-by-step explanation:

[tex]\frac{7x}{3y} + \frac{12x}{9y}[/tex]

To add the two fractions, you need a common denominator.  In this case, the lowest common denominator (LCD) is 9y.  That's because 9y is divisible by both 3y and 9y.

The first fraction must be changed so that its denominator is 9y.  Do this by multiplying both numerator and denominator by 3.

[tex]\frac{7x}{3y}\cdot\frac{3}{3}+\frac{21x}{9y}=\frac{21x}{9y}+\frac{12x}{9y}\\=\frac{21x+12x}{9y}\\=\frac{33x}{9y}[/tex]

Finally, this answer can be simplified ("reduced") by dividing both numerator and denominator by 3, their greatest common factor.

A peanut butter cookie recipe calls for 3 1/2 cups of flour to make 6 dozen cookies. How many cups of flour must be used to make 20

Answers

Complete Question

A peanut butter cookie recipe calls for 3 1/2 cups of flour to make 6 dozen cookies. How many cups of flour must be used to make 20 dozen?

Answer:

11 2/3 cups of flour

Step-by-step explanation:

From the above question:

6 dozen = 3 1/2 cups of flour

20 dozen = x

Cross Multiply

6 dozen × x = 20 dozen × 3 1/2 cups of flour

x = 20 dozen × 3 1/2 cups of flour/6 dozen

x = 20 × 7/2 /6

x = 140/2 ÷ 6

x = 140/2 × 1/6

x = 140/12 cups of flour

x = 11 8/12

= 11 2/3 cups of flour

Therefore, 11 2/3 cups of flour must be used to make 20 dozen.

Kevin rode 24 km in 2 hours. At that rate, how long would it take him to ride 120 km?

Answers

Answer:

10 hours

Step-by-step explanation:

We can convert the speed to km/h, and to do this, you simply have to find the amount Kevin rides in 1 hour. So,

24/2 = x/1

x = 12

So, now we see that Kevin rides at approximately 12 kmph. Now, instead of finding the distance, we need to find the hour at 120 km.

12/1 = 120/x

x = 10

_2. You have a part-time job 4 days per week, 5 hours per day. How many hours will you work in two weeks?
A) 10
B) 20
C) 40
D) 80

Answers

Answer:

C) 40

Step-by-step explanation:

For every one day your work is 5 hours.

1 day = 5 hours

Set up a proportion so it would be:

[tex]\frac{1 day}{5 hours} = \frac{4 days}{x hours}[/tex]

4 days x 5 hours = 20 hours/week

So now you know you know you work 20 hours/week, then multiply by 2 since they're asking how many hours will you work in two weeks:

20 hours x 2 weeks = 40 hours in two weeks

Was it easy? What were the hardest parts? What should i study more to pass it?

Answers

Step-by-step explanation:

To me yes.

Algebra is mostly memorization. If you know the formulas and know how to apply it, you should do good.

I say use this. Algebra topics are like building on top each other.

Heart of Algebra:

Review what the purpose of x in algebra.Then learn things like combining like terms, and solving for x.Since you know the basics of x, you can then review linear equations( imo, a big content of algebra). Stuff like slope, different linear forms, graphs of linear equations, and mostly linear equation word problemsThen you can review system of equations. since you know how to manipulate linear equations, etc.

Then move on to other algebra topics dealing with algebra like

functions, and different types of themexponents, and radicals rulesinequalities.sequences.These aren't the heart of algebra but study them they are useful and it important to know them.

Since you learned different function rules, we can move on to learning exponetial functions, graphs, and word problems.

Then finally, learn most hard thing in Algebra: Quadratics.

Pratice,practice, and practice and you will pass.

Try to memorize the formulas and know when to apply it.

Good Luck

noah wrote that 6+6=12 then has write 6+6-n=12 what property of equality justifies that the equation are equivalent​

Answers

Answer:

This may be written incorrectly.

Assuming that this is written correctly, then we have that:

6 + 6 = 12

is equivalent to:

6 + 6 - n = 12

Here the properties that we can add 0 in one side of the equality and this does not change the equality, so this only works if n = 0.

If we instead had:

6 + 6 = 12

is equivalent to:

6 + 6  - n = 12 - n

In this case, Noah used the additive or subtractive property of equality.

this property says that in an equality we can add (or subtract) the same value on both sides, and it does not change the equality.

Samuel ate
1/2 of the oatmeal cookies and 2/3 of the
sugar cookies for a total of 18 cookies. The number
of oatmeal cookies he ate was six more than the
number of sugar cookies he ate. How many sugar
cookies did he eat?

Answers

Answer:

9 sugar cookies

Step-by-step explanation:

Let the number of sugar cookies be x.

If the number of oatmeal cookies was six more than the number of sugar cookies, then oatmeal cookies can be represented by x + 6.

So, we know that Samuel ate half of the oatmeal cookies and 2/3 of the sugar cookies, for a total of 18 cookies. Let's represent this with an equation.

x + x + 6 = 18

2x + 6 = 18

2x = 12

x = 6

So x represents 6. Recall that he ate 2/3 of the sugar cookies, so 2 parts of sugar cookies is 6.

Therefore, we can do this:

(3/2) x 6 = 9 cookies

This is essentially saying, "I want to find 3 parts if 2 parts is 6 cookies."

He ate 9 sugar cookies.

Simon wants to earn as many points as possible in one turn in a game. Two number cubes whose sides are numbered 1 through 6 are rolled. He is given two options for the manner in which points are awarded in the turn. OPTION A: If the sum of the rolls is a prime number, Simon receives 15 points. OPTION B: If the sum of the rolls is a multiple of 3, Simon receives 12 points. Which statement best explains the option he should choose?

Answers

Answer:

The answer is "Option A"

Step-by-step explanation:

In point A:  

Rolling an indivisible prime number:  

The 2 can be moved just 1 way (1,1)  

The 3 can be moved two different ways (1,2) or (2,1)  

The 5 can be moved four different ways (1,4) or (2,3) or (3,2) or (4,1)  

The 7 can be moved six different ways (1,6) or (2,5) or (3,4) or (4,3) or (5,2) or (6,1)  

The 11 can be moved two different ways (5,6) or (6,5)  

There are 26 approaches to move two dice at a time.  

The likelihood of rolling an indivisible number is: [tex]=\frac{(1 + 2 + 4 + 6 + 2)}{36} =\frac{15}{36}[/tex]

Because rolling an indivisible number is worth 15 focuses, the normal worth is [tex](\frac{15}{36}) \times 15 = 6.25[/tex]

In point B:

When the rolling is a numerous of 3:  

The 3 can be moved two different ways (1,2) or (2,10  

The 6 can be moved five different ways (1,5) or (2,4) or (3,3) or (4,2) or (5,1)  

The 9 can be moved four different ways (3,6) or (4,5) or (5,4) or (6,3)  

The 12 can be moved just 1 way (6,6)  

The likelihood of rolling a numerous of 3 will be:[tex]= \frac{(3 + 6 + 9 + 12)}{36} = \frac{12}{36}[/tex]

because the rolling in the various of 3 is worth 12 focuses, the normal worth is[tex](\frac{12}{36}) \times 12 = 4[/tex]
