Hi! I'm happy to help!

To first solve this, we need to make those mixed numbers improper fractions.

To make 4 1/2 an improper fraction, you have to turn 4 into halves (multiply four by 2) then add the extra half, giving you 9/2.

[tex]\frac{9}{2}[/tex]​ ÷(−1[tex]\frac{3}{7}[/tex]​ )

Now, we turn 1 3/7 into an improper fraction. We turn 1 into sevenths (multiply 1 by 7) then add the other 3 sevenths, giving you 10/7.

[tex]\frac{9}{2}[/tex]​ ÷(−[tex]\frac{10}{7}[/tex]​ )

From here, we need to turn this problem into a multiplication problem in order to solve. Since multiplication is the opposite of division, we need to get the opposite of something, so we use our second fraction and flip it.

[tex]\frac{9}{2}[/tex]​ ×(−[tex]\frac{7}{10}[/tex]​ )

Now, we multiply the top by the top, and the bottom by the bottom. (any positive multiplied by a negative gives a negative)

-[tex]\frac{63}{20}[/tex]

Since we cannot simplify, our final answer is -63/20.

Answer:

Step-by-step explanation:

16. Use Euclid Perfect Number formula:

If [tex]2^{n} -1[/tex]a a prime number, then [tex]2^{n-1}(2^{n} -1)[/tex] is a perfect number. 6 is a perfect number when n=2 Let try when n=3

[tex]2^{2} (7)=28[/tex]

So 28 is a perfect number

We will find that the ratio of 3 less than k to 2 more than k is:

(k - 3):(k + 2)

The ratio between two numbers A and B can be written as:

A:B

This is the ratio of A to B

and

B:A

Is the ratio of B to A.

Then for the ratio of 3 less than k to 2 more than k we have:

"3 less than k" is: k - 3

"2 more than k" is: k+ 2

Then the ratio is:

(k - 3):(k + 2)

3,700 x 11 Walks= 40, 700

Answer:

x=-5

Step-by-step explanation:

2(5x-4)=10x-8

-3(3x-1)=-9x+3

10x-8-9x+3

x=-5

The answer you are looking for is -5.

Writing out the equation,

2(5x-4)-x-3(3x-1)

Using the Distributive Property for 2(5x-4) and -3(3x-1),

10x-8-x-9x+3

Using the Associative Property,

10x-x-9x-8+3

Simplifying the similar terms,

9x-9x-8+3

Canceling both "9x" terms, since 9x-9x is obviously 0,

0-8+3, or simply just -8+3.

-8+3=-5

So, therefore the final answer is -5.

I hope that this has helped you. Enjoy your day, and take care.

a = 32

Step-by-step explanation:

This is a right triangle and the square value of hypotenuse is equal to sum of square value of other two side lengths

68^2 = 60^2 + a^2

4624 = 3600 + a^2

4624 - 3600 = a^2

1024 = a^2 find the root for both sides

32 = a

Step-by-step explanation:

[5+3x] is an expression that cannot be added because 5 is a natural interger but 3x is an unknown

and therefore it cannot be divided by 2 to get 4

Better example :

if the question will give 4x , then

it should be [5x+3x]/2 = 8x/2 = 4x

it's obvious from the example I gave that 8x can be divided by 2 to give 4x
