Answer: Option A

P = \$\ 1.05

Step-by-step explanation:

If we have 5 cans of ketchup they cost $ 5.25. Then the unit price of cans is what each can costs individually.

The unit price should then be less than $ 5.25, and that is the price for 5 cans and we want to know the price for just one can of ketchup.

Then to calculate the price of each can divide the price of the 5 cans by 5.

P = \frac{5.25}{5}

P = \$\ 1.05

What is the product? StartFraction x squared minus 16 Over 2 x + 8 EndFraction times StartFraction x cubed minus 2 x squared + x
zubka84 [21]

Answer:

[x(x - 1)(x - 4)]/(2(x + 4))

Step-by-step explanation:

We want to find;

[(x² - 16)/(2x + 8)] * [(x³ - 2x² + x)/(x² + 3x - 4)]

Now,

x² - 16 can be factorized as;

(x + 4)(x - 4)

Also, 2x + 8 can be factorized as;

2(x + 4)

Also, (x³ - 2x² + x) can factorized as;

x[x² - 2x + 1] = x[(x - 1)(x - 1)]

Also,(x² + 3x - 4) can be factorized out as; (x - 1)(x + 4)

So plugging in these factorized forms into the equation in the question, we have;

[(x + 4)(x - 4)/(2(x + 4))] * [x[(x - 1)(x - 1)] /((x - 1)(x + 4))

This gives;

((x - 4)/2) * x(x - 1)/(x +4)

This gives;

[x(x - 1)(x - 4)]/(2(x + 4))

Which of the following examples is an error of addition by one? A. 7363 + 1535 = 8798 B. 3415 + 2174 = 5589 C. 5167 + 4622 = 978
Sloan [31]

Answer:

(A) and (B)

Step-by-step explanation:

(A) The given example is:

7363 + 1535

Adding these two numbers, we get

8898

which is an error of addition by one.

Thus, this option is correct.

(B)The given example is:

3415 + 2174

Adding these two numbers, we get

6589

which is an error of addition by one.

Thus, this option is correct.

(C)The given example is:

5167+4622

Adding these two numbers, we get

9789

which is not an error of addition by one.

Thus, this option is not correct.

(D) The given example is:

2683+6215

Adding these two numbers, we get

8898

which is not an error of addition by one.

Thus, this option is not correct.
