Simplify the expression: –3(9 − x) =

steposvetlana [31]

Answer:

Expand $-3(9-x): -27 + 3x$

Step-by-step explanation:

$-3(9-x)$

Apply the distributive law: $a(b-c)=ab-ac$

$a = -3, b=9, c=x$

$=-3*9-(-3)x$

Apply minus - plus rules:

$-(-a)=a$

$= -3*9+3x$

Multiply the numbers: $3 * 9 = 27$

$=-27+3x$

This is the angle similarity of triangles btw. I will give brainliest to whoever finds the missing angle measures.

A triangle should always add up to 180 degrees. So just add up the angles you have and subtract them from 180

Which measure is equivalent to 25,200 seconds? 1 min = 60 s 1 h = 60 min

sertanlavr [38]

Solution:

Note that:

1 min = 60 sec
1 h = 60 min.

The given time is in seconds. Convert it into minutes by dividing it by 60.

=> 25,200 seconds = 25,200 ÷ 60 minutes = 420 minutes

The obtained time is in minutes. Convert it into hours by dividing it by 60.

=> 420 minutes = 420 ÷ 60 hours = 7 hours

We can conclude that:

25,200 seconds = 420 minutes = 7 hours
