Brandy set her watch 4 seconds behind and it falls behind another 1 second every day. How many days had it been since brandy las

kari74 [83]

Answer:

18 days

Step-by-step explanation:

Let x represent number of days.

We have been given that Brandy's watch falls 1 second every day. So Brandy's watch will fall $1x$ seconds behind in x days.

We are also told that Brandy set her watch 4 seconds behind, so Brady's watch will be behind by total $x+4$ seconds in x days.

Since Brady's watch is 22 seconds behind, so we will equate $x+4$ by 22 to solve for x as:

$x+4=22$

$x+4-4=22-4$

$x=18$

Therefore, Brandy set her watch 18 days ago.

-10 ≥ 2x + 14

-24 ≥ 2x [subtract 14 from both sides]

2x ≤ -24 [read right to left]

x ≤ -12 [divide both sides by 2]

Check:

Let x = -13 (It is ≥ -12)

Is this true: -10 ≥ 2(-13) + 14 ?

-10 ≥ -26 + 14 ?

-10 ≥ -14 ?yes

Let x = -11 (it is not ≥ -12)

Is this false:: -10 ≥ 2(-11) + 14 ?

-10 ≥ -22 + 14 ?

-10 ≥ -8 ?yes
