Answer:

16/24

Step-by-step explanation:

So you need to get a common denominator before you try to answer the whole question. Turn the denominator into 24. Since you would multiply 8 by 3, multiply the 7 by 3. That would make 21/24. Make the 3 a 24, multiplying it by 8 and doing the same to the 2 making 16/24.

If x=10, write an expression in terms of x for the number 5,364
LenKa [72]

Answer:

(5,354 + x)

or

536.4*x

Step-by-step explanation:

We know that x = 10.

Now we want to write an expression (in terms of x) for the number 5,364.

This could be really trivial, remember that x = 10.

Then:  (x - 10) = 0

And if we add zero to a number, the result is the same number, then if we add this to 5,364 the number does not change.

5,364 = 5,364 + (x - 10) = 5,364 + x - 10

5,364 = 5,354 + x

So (5,354 + x) is a expression for the number 5,364 in terms of x.

Of course, this is a really simple example, we could do a more complex case if we know that:

x/10 = 1

And the product between any real number and 1 is the same number.

Then:

(5,364)*(x/10) = 5,364

(5,364/10)*x = 5,364

536.4*x = 5,364

So we just found another expression for the number 5,364 in terms of x.
