RS=4y+4, ST=3y+4, and RT=43 <br> What is the value of y?

Shkiper50 [21]

The value of y is 5

<h3>How to determine the value </h3>

From the given line, it can be concluded that:

The segment RT is divided into RS and ST

But we have the following parameters

The length of the sides are:

RS=4y+4
ST=3y+4
RT=43

Since RT is RS added to ST:

We have;

RT = RS + ST

substitute the values

43 = 4y + 4 + 3y + 4

collect like terms

43 = 4y + 3y + 4 + 4

Add like terms

43 = 7y + 8

43 = 7y + 8

Make '7y' subject of formula

7y = 43 - 8

7y = 35

Make 'y' the subject of formula

y = 35/ 7

y = 5

Thus, the value of y is 5

A n =−1+3(n−1) an=−1+3(n−1) what is the 55 term in the sequence

Sindrei [870]

ANSWER

$a_{55}=161$

EXPLANATION

The general term for the sequence is

$a_n=-1+3(n-1)$

To find the 55th term, we have to substitute
$n = 55$
in to the general term and simplify.

This implies that,

$a_{55}=-1+3(55-1)$

$a_{55}=-1+3(54)$

$a_{55}=-1+162$

$a_{55}=161$

Therefore the 55th term is 161.

Suppose you know that <T and<S are supplementary, and that m<T=3(m<S). How can you find m<T?

stealth61 [152]

Answer:

∠T = 135°

Step-by-step explanation:

Supplementary angles sum to 180°, thus

∠T + ∠S = 180

However, ∠T = 3∠S, hence

3∠S + ∠S = 180

4∠S = 180 ( divide both sides by 4 )

∠S = 45°, hence

∠T = 180° - 45° = 135°
