Answer:
x< 3
Step-by-step explanation:
first you do the things between ( )
but here you can't change anything between te ( )
then you do the multiplying and dividing
so in this case you get
-3-24x-36>-111
then you do + and -
so in this case you get
-24x - 39 > -111
then you want to get the x so you bring everything without an x to the other side
here you get
-24 x > -111+ 39
-24x> -72
then you separate the x completely
so you get
x<-72/-24
x< 3
above you changed the > to an < because you divide with a negative number
Okay, here is how i got my answer. i divided 300 by 1.08 because 68 seconds translates to 1 minute and 8 seconds. I got 277.77 repeated but you can round it to 278. This is a rate so you might wanna write it like this: 277/minute
Answer:
You can take this equation into two approaches.
#1 subtracting 4x from both sides:
-3x+10=4x-20 (subtract 4x from each side)
-7x+10=-20 (then subtract 10 from each side)
-7x=-30 (then divide by -7 to get x by itself)
x=30/7
#2 Add 3x to both sides:
-3x+10=4x-20 (Add 3x to both sides)
10=7x-20 (then add 20 to each side)
30=7x (divide both sides by 7)
30/7=x
Either way you do it you will get x=30/7 as your answer.
Hope this helps ;)
Notice that both equation has a 2f term in them
solve for 2f for both eqs.
2f= 736-6n
2f= 920-10n
since they both equal to 2f, yo can set them equal to each other
736-6n = 920-10n
and solve for n if you want
