I’m going to say the top one it seems like that would be correct
Original price is $150 so you times 150 by 0.40
150 x 0.40 = 60
So you take the $150 and you subtract $60 from $150
150 - 60 = 90
So the answer is $90
34x=0
So we need to isolate x. Since 34 is multiplied by x, we need to isolate x by moving 34 over the equal sign. Whenever you move something over the equal sign, the opposite is done. For 34, instead of being multiplied, it will be divided.
34x=0
X=0/34
Then you solve for x
X=0
Hope this helps!
Words over minutes.
So 36/(2/3)
Basically saying
36 * (3/2) = 54
6 hikers = 4.5 lbs of trail mix
4.5 divided by 6= .75 lbs each hiker.
