Step-by-step explanation:

Conversion a mixed number 3 1/

4

to a improper fraction: 3 1/4 = 3 1/

4

= 3 · 4 + 1/

4

= 12 + 1/

4

= 13/

4

To find new numerator:

a) Multiply the whole number 3 by the denominator 4. Whole number 3 equally 3 * 4/

4

= 12/

4

b) Add the answer from previous step 12 to the numerator 1. New numerator is 12 + 1 = 13

c) Write a previous answer (new numerator 13) over the denominator 4.

Three and one quarter is thirteen quarters

Conversion a mixed number 2 1/

3

to a improper fraction: 2 1/3 = 2 1/

3

= 2 · 3 + 1/

3

= 6 + 1/

3

= 7/

3

To find new numerator:

a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/

3

= 6/

3

b) Add the answer from previous step 6 to the numerator 1. New numerator is 6 + 1 = 7

c) Write a previous answer (new numerator 7) over the denominator 3.

Two and one third is seven thirds

Add: 13/

4

+ 7/

3

= 13 · 3/

4 · 3

+ 7 · 4/

3 · 4

= 39/

12

+ 28/

12

= 39 + 28/

12

= 67/

Answer:

\(\Large \boxed{\textbf{12}}}\)

Step-by-step explanation:

​To find the square​​ root of 144, we​​ can use prime​​ factorisation.​

Finding a number that, when multiplied by itself, gives another number can be done using square roots. For example, since 2 + 2 = 4, the square root of 4 is 2. When you meet the square root sign, which looks this: \(\sqrt{x}\), you should look for the number that, when multiplied by itself, gives you the result under the symbol.

The process of dividing a composite number into its prime factors is known as prime factorisation. A number with more than two factors is called a composite number, whereas a number with exactly two factors—the number 1 and itself—is called a prime number. A number's prime factors can be discovered using a variety of techniques, including the factor tree method and the division method.

Step 1: Determine the prime factors of 144

We can start by dividing 144 by the smallest prime number, which is 2. We get:

\(\frac{144}{2} = 72\)

So, 2 is a factor of 144. We can repeat this process with 72:

\(\frac{72}{2} = 36\)

So, 2 is a factor of 144 twice. We can continue with 36:

\(\frac{36}{2} = 18\)

Again, 2 is a factor of 144 twice. We can continue with 18:

\(\frac{18}{2} = 9\)

Now, we cannot divide by 2 anymore, so we move on to the next prime number, which is 3:

\(\frac{9}{3} = 3\)

So we get 3, since it's a prime number, we don't need to divide it again, since we will get the same result — 3.

We have now found all the prime factors of 144:

144 = \( \text{2 x 2 x 2 x 2 x 3 x 3} \)

Step 2: Group the prime factors of 144 in pair

We can group the prime factors in pairs of two:

\( \text{144 = 2 x 2 x 2 x 2 x 3 x 3 = ( 2 x 2) x (2 x 2) (3 x 3)} \)

Step 3: Take the product of one factor from each pair.

We can take one factor from each pair and multiply them together:

\(\sqrt{144} = \sqrt{\text{(2 x 2) x (2 x 2) x (3 x 3)}} \text{= 2 x 2 x 3 = 12}\)

Therefore, the square root of 144 is 12.

We can also check our answer by squaring 12:

\( 12^{2} = \text{144} \)

So, our answer is correct!

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A

Answer:

A = -6; B = 15

Step-by-step explanation:

4x-Ay=15

-4x+6y=B

This is your system of equations. For it to have infinitely many solutions, the lines have to be the same. This means that if you multiply one equation by a constant, you should be able to get the other one.

With this system, you have 4x in one equation and -4x in the other. You can use this to figure out the constant. Because -4 is, well negative four, you know that the second equation is the opposite of the first; everything is multiplied by -1.

That means A = -6 and 15 = -B (The other coefficients and constants of the equations also have to be opposites.), and you can solve for B now. Divide by -1 to get B=15.

Answer:

This represents a proportional relationship, the ratios are equivalent, and the constant of proportionality is 7.7.

Step-by-step explanation:

Since we know that six cell phones weigh 46.2 oz, we can divide 46.2 by 6 to find the weight of each, so 46.2/6=7.7.

We also know that fourteen cell phones weigh 107.8 oz, so we divide 107.8 by fourteen and get 7.7 as well.

Since both ratios equal 7.7 oz per cell phone, the ratios are equal and the relationship is proportional.
