Least common denominator of 4/19 and 7/10

Answer:

5x

Step-by-step explanation:

you have to subtract 5x to 1y

Answer:

10

Step-by-step explanation:

f(x)=3x-1

g(x)= - 2x-4.  

g( f(-2))

First find f(-2)

Let x = -2

f(-2)=3(-2)-1 = -6-1 = -7

Now find g(-7)

g(-7) = -2(-7) -4 = 14 -4 = 10

Answer:

[tex]f(x) = 3x - 1 \\ g(x) = - 2x - 4 \\ g(f(x)) = - 2(3x - 1) - 4 \\ g(f(x)) = - 6x + 2 - 4 \\ g(f(x)) = - 6x - 2 \\ g(f( - 2)) = - 6( - 2) - 2 \\ g(f( - 2)) = 12 - 2 \\ \boxed{g(f( - 2)) = 10}[/tex]

Answer:

12.5%

Step-by-step explanation:

The question stated that 4 of her teeths have fillings out of her 32 teeth. From this info, we can represent 4 and 32 in fraction form; we can write it as 4/32. Now all you have to do is write 4/32 as a fraction. Divide 4 by 32 = 0.125. Multiply 0.125 by 100 to get 12.5%. Therefore, the answer is 12.5%.

Hope this helps!

Can you mark me brainliest pls? (Only if you want, I won’t mind if you don’t)

Answer:

12.5%

Step-by-step explanation:

There are two ways to go about this:

One way...Set up a proportion

4/32 = x/100

You know that 32 is basically 100% and you are trying to figure out the missing percentage which is represented by "x"

All you have to do once you set up this proportion is to cross multiply...

32 · x = 32x

4 · 100 = 400

and you are left with:

32x = 400

Divide both sides to isolate "x"

x = 12.5

Thus, your answer would be 12.5%

Second Way...

You can divide 4 by 32.

4 ÷ 32 = 0.125

Then multiply by 100 to get the percent

0.125 · 100 = 12.5

And you get 12.5%

Hope this helps!!! Let me know if you have any further questions :)

Answer:

1.Geometric proofs can be written in one of two ways: two columns, or a paragraph. A paragraph proof is only a two-column proof written in sentences. ... A two-column geometric proof consists of a list of statements, and the reasons that we know those statements are true.

2.ray AB is not same as ray BA as ray AB has the starting point A and ray BA has B as the starting point.

3.∠ABC  refers to an angle, a geometric object.

m∠ABC  refers to the measure of  ∠ABC  which is a real number describing how “open” the angle is.

Answer:

The price per ounce is  about 6 cents .

Step-by-step explanation:

2.5 pounds costs $2.51

      1 ounce cost $ ?

We need to convert the pounds to ounces so we can answer the question.

1 pound = 16 ounces

2.5 pounds = 2.5 *16 = 40 ounces

Substitute the 2.5 pounds by 40 ounces

40 ounces costs $2.51

     1 ounce cost $ ?

$? = (1 * 2.51)/ 40 = .06275 ≅.06

1 ounce is $.06 or  6 cents

Hint :-

Solution :-

We need to find out the sum of 50 terms of the given sequence . After splitting the given sequence ,

[tex]\implies S_1 = \dfrac{1}{2},\dfrac{1}{4},\dfrac{1}{8}[/tex] .

We can see that this is in Geometric Progression where 1/2 is the common ratio . Calculating the sum of 25 terms , we have ,

[tex]\implies S_1 = a\dfrac{1-r^n}{1-r} \\\\\implies S_1 = \dfrac{1}{2}\left[ \dfrac{1-\bigg(\dfrac{1}{2}\bigg)^{25}}{1-\dfrac{1}{2}}\right] [/tex]

Notice the term [tex]\dfrac{1}{2^{25}}[/tex] will be too small , so we can neglect it and take its approximation as 0 .

[tex]\implies S_1\approx \cancel{ \dfrac{1}{2} } \left[ \dfrac{1-0}{\cancel{\dfrac{1}{2} }}\right] [/tex]

[tex]\\\implies \boxed{ S_1 \approx 1 }[/tex]

[tex]\rule{200}2[/tex]

Now the second sequence is in Arithmetic Progression , with common difference = 3 .

[tex]\implies S_2=\dfrac{n}{2}[2a + (n-1)d] [/tex]

Substitute ,

[tex]\implies S_2=\dfrac{25}{2}[2(4) + (25-1)3] =\boxed{ 908} [/tex]

Hence sum = 908 + 1 = 909

Hi There!

9f+5=77

Make sure all numbers are on the right side of the equation.

9f=77-5

9f=72

Now divide both sides by 9 to isolate f:

f=8

Answer:

c

Step-by-step explanation:

the line is going down so we know it has to be a negative slope narrowing the answer choices down to a and c but when you pick a point to check for the reigon (i used 0,0 as a basic point) only c satisfies the inequality while keeping the point , not a.

Answer:

2.1+5.8-4.1  

= 3.8

Step-by-step explanation:

2.1 + ( 5.8 - 4.1 )

Add 2.1 and 5.8 to get 7.9

7.9 - 4.1

subtract 4.1 from 7.9 to get 3.8

3.8

Answer:

False is the correct answer.

Answer:

B) [tex]-\frac{a}{-b}[/tex]

Step-by-step explanation:

1. First, we have to know that two negatives equal positive.

2. Given the information above, [tex]-\frac{-a}{b}[/tex] can simplify to [tex]\frac{a}{b}[/tex].

3. Let's go through each answer choice and see which one also simplifies to [tex]\frac{a}{b}[/tex].

A:

B:

Therefore, the answer is B) [tex]-\frac{a}{-b}[/tex].

Answer:

See below

Step-by-step explanation:

It has only one solution when the line mx + 1 is parallel to one part of |2x - 4|.

As per graph, we see m = 2 makes it parallel to y = 2x - 4. This is the only solution.

---------------------------

Now, as I understand, you are looking for 2 solutions instead of one. It means the line mx + 1 will have 2 points of intersection with the line |2x - 4|.

One of those solutions is attached as well, where m = 1. And you may get many more options for this.
