Answers

Answer:

x = 7/5

I hope this helps

Step-by-step explanation:

7x - [5 + (3x - 2)] = x - (4x - 5) + (2x - 1)

7x - 5 -3x +2 = x -4x +5 +2x -1

4x -3 = -x +4

4x +x = 4+3

5x = 7

x = 7/5

Given:

The table of values.

v and x are in direct proportion.

To find:

The formula connecting v and x.

Solution:

(a)

v and x are in direct proportion.

[tex]v\propto x[/tex]

[tex]v=kx[/tex]            ...(i)

Where, k is the constant of proportionality.

Putting v=13.6 and x=32.64, we get

[tex]13.6=k(32.64)[/tex]

[tex]\dfrac{13.6}{32.64}=k[/tex]

[tex]\dfrac{5}{12}=k[/tex]

Putting the value of k in (i), we get

[tex]v=\dfrac{5}{12}x[/tex]

Therefore, the required formula that connecting v and x is [tex]v=\dfrac{5}{12}x[/tex].

(b)

Putting v=n and x=8.16, we get

[tex]n=\dfrac{5}{12}(8.16)[/tex]

[tex]n=3.4[/tex]

Therefore, the value of n is 3.4.

Step-by-step explanation:

To solve this, use the Pythagorean Theorem: a² + b² = c². You insert the measurements you have: 3² + b² = 5² or 9 + b² = 25. To solve this, subtract 9 from both sides: b² = 16. To solve for b (length) specifically, find the square root of 16: 4.

There are two questions :v

Answers

Answer:

Step-by-step explanation:

One

v^2 - 16

This formation is called the difference of squares. That's because there are 2 squares v^2 and 16. The key to this question is the minus sign.

The square root of v^2 = v

The square root of 16 = 4

You get (v + 4)(v - 4)

Let's see what happens when you expand it.

v*v = v^2v*(-4) = - 4vv*(4) = 4v4*-4 = - 16

Look what happens when you add these 4 terms together.

v^2 - 4v + 4v - 16v^2 - 16

is what is left. The two middle terms cancel out.

Two

This one is a perfect square

w^2 + 16w + 64

(w + 8)(w + 8)

Notice both factors are the same. You might wonder how I new that.

w^2 is a perfect square so take the square root.  ....   v      

64 is a perfect square so take the square root    .....    8

Now you have to work backwards to see if it is right.

w*w = w^2w*8 = 8w8*w = 8w8^2 = 64

Adding you get w^2 + 16w + 64 which is what you started with.

What are credit cards and their uses?

A credit card is a kind of credit service, delivered by banks that permit customers to borrow money within a pre-approved credit limit. It allows customers to make purchase transactions on goods and services.


Since option A, C and D can be omitted because, on parking fee, lotto ticket and soda spending through credit card can be possible but more likely because the spending on these items are very less and service provider do not intentionally accept the credit card
But engine repair is most likely to be paid from the credit card, because the liquidity in the business is very much high comparatively.
