Step-by-step explanation:

116° + y° = 180°. (sum of angles on a straight line = 180°)

Therefore y° = 64°.

The angles x°, y°, 72° and 125° are interior angles of a quadrilateral. (4-sided polygon)

In a quadrilateral, sum of interior angles = 360°.

So x° = 360° - y° - 72° - 125°

= 360° - 64° - 72° - 125°

= 99°.

Hence x° = 99°.

Answer:

x = 99°

Step-by-step explanation:

<u>First find y as its on straight line with 116°</u>

y = 180° - 116° = 64°

<u>Now, the sum of interior angles of a quadrilateral is 360°</u>

x = 360° - (64° + 125° + 72°) = 99°

Step-by-step explanation:

First, calculate her balance after the deposit in June:

150 + 25

= 175

Then, calculate her balance after July's withdrawl:

175 - 105

= 70

So, her balance in August is $70

Two more than 5 times a number is greater than or equal to 3

jenyasd209 [6]

Answer:

n ≥ 1/5

Step-by-step explanation:

Let the number be n. Then 5n + 2 ≥ 3.

If you want to solve this for n, then subtract 2 from both sides, obtaining:

5n ≥ 1. Isolate n by dividing both sides by 5. Then we have n ≥ 1/5

Last questions, plz help

Goryan [66]

Answer:

9. $a_n=7+6n$

10. $a_n=a_{n-1}+7$

Step-by-step explanation:

9. Given the sequence

$13, 19, 25, ...$

In this sequence,

$a_1=13\\ \\a_2=19\\ \\a_3=25\\ \\...$

Note that

$a_2-a_1=19-13=6\\ \\a_3-a_2=25-19=6,$

then the common difference in this sequence is $d=6$

You have

$a_1=13\\ \\d=6,$

then the explicit formula is

$a_n=a_1+(n-1)d\\ \\a_n=13+(n-1)\cdot 6\\ \\a_n=13+6n-6\\ \\a_n=7+6n$

10. Given the sequence

$-10,-3, 4, 11, ...$

In this sequence,

$a_1=-10\\ \\a_2=-3\\ \\a_3=4\\ \\a_4=11\\ \\...$

Note that

$a_2-a_1=-10-(-3)=-10+3=-7\\ \\a_3-a_2=-3-4=-7\\ \\a_4-a_3=11-4=7,$

then the common difference in this sequence is $d=7$

You have

$a_1=-10\\ \\d=7,$

then the recursive formula is

$a_n=a_{n-1}+d\\ \\a_n=a_{n-1}+7$
