Answer:

$\mathsf {x = 76}$

Step-by-step explanation:

The given pair of angles lie on a line, hence they are classified as linear angles. They possess the property by which their sum is equal to 180°.

$\textsf {Solving :}$

$\implies \mathsf {x + 17 + 87 = 180}$

$\implies \mathsf {x + 104 = 180}$

$\implies \mathsf {x = 180 - 104}$

$\implies \mathsf {x = 76}$

A 1 inch thick stack of printer paper is found to contain 175 sheets to the nearest thousandth of an inch how thick is each shee

MariettaO [177]

the answer you're looking for, rounded to the nearest thousandth, is 0.006 and we get that answer because we must round 0.0057 to the nearest thousandth, meaning that we must look at the seven, and realize that the seven tells us that the 5 is supposed to be a 6 because we are rounding to the nearest thousandth. So the answer is 0.006 I hope that this helps!

4 - 3 = 1

1 - 3 = -2

-2 - 3 = -5

-5 - 3 = -8

It's the arithmetic sequence.

$a_n=a_1+(n-1)d$

$a_1=4,\ d=-3$

substitute

$a_n=4+(n-1)(-3)=4-3n+3=-3n+7$

Answer: $a_n=-3n+7$
