Convert 15 2/3 to an improper fraction;

- 15 × 3 + 2/3 - 5 2/3

Simplify 15 × 3 to 45

- 45 + 2/3 - 5 2/3

Simplify 45 + 2 to 47

- 47/3 - 5 2/3

Convert 5 2/3 to an improper fraction

- 47/3 - 5 × 3 + 2/3

Simplify 15 + 2 to 17

- 47/3 - 17/3

Join the denominators

-47 - 17/3

Simplify

- 64/3

Convert to a mixed fraction;

<u>-21 \frac{1}{3}</u>

How do I choose a method then find the product for 70x55?
Molodets [167]
Okay so you would line them up then you would multiple 5 and 0 then 7 and 5 and then you add a 0 then you would get the answer 350 then you would multiply the same numbers then the answer you would get is 3500 then you add 3500+350=3850

Use the chart to multiply the binomial by the trinomial.
melomori [17]

Answer:

Option (1) is correct.

The product of  (y+3)(y^2-3y+9) is  y^3+27

Step-by-step explanation:

Given, (y+3)(y^2-3y+9)

We have to find the product of above,

We have to multiply each term as ,

(y+3)(y^2-3y+9) can be written as,

\Rightarrow y(y^2-3y+9)+3(y^2-3y+9)

When we multiply each term we get,

\Rightarrow (y^3-3y^2+9y)+(3y^2-9y+27)

These terms are same as we have filled in table below.

On adding like terms we get,

\Rightarrow y^3-3y^2+9y+3y^2-9y+27

\Rightarrow y^3+27

Thus, the product of  (y-3)(y^2-3y+9) is  y^3+27

What is a of n equal to?<br> What is the 10tn term in the sequence?
Helen [10]

Answer:

nth term, T_n=1(2)^n^-^1

10th term, T_1_0=512

Step-by-step explanation:

From the question;

  • We are given the first term, a_1=1
  • The common ratio, r = 2

We are required to write the formula of getting nth term and find the 10th term of the sequence;

  • We need to know that for nth term in a geometric sequence, we use the formula;

T_n=a_1r^n^-^1

Therefore, in this case;

nth term will be given by;

T_n=1(2)^n^-^1, where n is the term in the sequence;

Therefore;

To get the 10th term of the sequence;

T_1_0=1(2)^1^0^-^1

T_1_0=1(2)^9

T_1_0=512

Therefore, the tenth term of the sequence is 512
