Find the 3rd term of an arithmetic sequence with t2= 9/2 and t5= 6

1 answer:

5 0

<span>Well a simply way is to look at the problem as

Term 1 | 2 | 3 | 4 | 5 ----------------------------
Value | 9/2 | | | 6

There are 3 terms from 2 to 5 and the value increases 6 - 9/2 = 3/2 so the common difference is 3/2 divided by 3 so the common difference is 1/2 so to find the 3rd term add 1/2 to the 2nd term the pattern is each term is increasing by 1/2.. or 1/2 is added to the previous term. </span>

Solve for x each is a parallelogram

jonny [76]

Answer:

UW = EW+UE=2×EW because, EW=UE

7x-2=2×6= 12

7x=14

x=14/7

x=2

<h2>2 is the right answer.</h2>

x + 80 = 180 - (64 + 36)

x + 80 = 180 - 100

x + 80 = 80

x = 0

<h2>0 is the right answer.</h2>

What is -1.1 repeating as a fraction

Thepotemich [5.8K]

$Hey \\ There!$

$\frac{-1.1}{1} ( \frac{10}{10} )\\ \\ -1.1(10) = -11 \\ \\ 1(10)= 10 \\ \\ \\ Fraction: \frac{-11}{10}$ this is also $equal$ to: $-1\frac{1}{10}$

Your answer would probably be: $\frac{-11}{10} = -1\frac{1}{10}$

Good luck on your assignment and enjoy your day!

The diagram shows a parallelogra,. 3x-15, 2x, 2x, 2x+24, work out x

liraira [26]

Answer:

x = 39

Step-by-step explanation:

In a parallelogram the opposite angles are congruent, thus

3x - 15 = 2x + 24 ( subtract 2x from both sides )

x - 15 = 24 ( add 15 to both sides )

x = 39
