How many integers $n$ satisfy $-4n\ge 12$ and $n+5>2$??

Dahasolnce [82]

-4n ≥ 12 ==> n ≤ -3

n + 5 > 2 ==> n > -3

But n cannot be both less than/equal to -3 AND greater than -3, so there are no integers n that satisfy these inequalities.

Angle bisectors AX and of triangle ABC meet at point I. Find angle C in degrees, if AIB = 109.

UkoKoshka [18]

Answer:

angle C = 38 degrees

Step-by-step explanation:

Refer to attached figure (sorry, forgot to attach earlier)

Given

AIB = 109

Let

CAX = XAB = x

CBY = YBA = y

XIB = YIA = x+y ........exterior angles

XIB = YIA = 180-109 = 71 ............ sum of angles on a line

x+y = 71

ACB = 180 - 2x -2y ................. sum of angles of a triangle

= 180 - 2(x+y)

= 180 - 2(71)

= 180 - 142

= 38

Andy has a collection of movie dvds. in andys collection 3/5 of the dvds are action 1/4 of the dvds are comedy. andy said that 4

Cerrena [4.2K]

This question is based on greatest common multiple.

Answer:

Cynthia is right that Andy made an error.

Step-by-step explanation:

As per Andy, action dvds are = $\frac{3}{5}$

And comedy dvd's are = $\frac{1}{4}$

So, in total these become = $\frac{3}{5}+ \frac{1}{4}$

= $\frac{12+5}{20}$ = $\frac{17}{20}$

This is not 4/9 as per Andy.
