Answer:

Step-by-step explanation:

-21+-13+20=14

This is true because when subtracting negatives by negatives you pretty much add them and then when you add a positive to a negative you are technically removing the negative by the amount you are adding.

In short its kind of like using inverse operation in a way.

Hope this helps and have a nice day

siny=s/8
tany=s/t

$\\ \tt\longmapsto cosy=\dfrac{siny}{tany}$

$\\ \tt\longmapsto cosy=\dfrac{s/8}{s/t}$

$\\ \tt\longmapsto cosy=8/t$

Secy=1/cosy=t/8

Find the value of x that will make A||B. 5x + 9 A B 6x-2 X = [?] Enter

givi [52]

Answer:

$x = 11$

Step-by-step explanation:

Given

Parallel lines A and B

Required

Find x

For A and B to be parallel, then 5x + 9 and 6x - 2 are alternate interior angles

And alternate interior angles are always equal

This means that

$5x + 9 = 6x - 2$

Collect like terms

$5x - 6x = -2 -9$

$-x = -11$

Multiply both sides by -1

$-1 * -x = -11 * -1$

$x = 11$
