Answer:
The second one
Step-by-step explanation:
This is because it is asking for a budget meaning that you have to spend less or equal to 200
I’ll do an example problem, and I challenge you to do this on your own!
If the example is find the difference between 0645 and 1200, we know that there are 60 minutes in an hour, so 0645 is 6 hours and 45 minutes or 6+45/60=6+3/4 of an hour by dividing both the numerator and denominator by 15. Finding that in minutes, we have 60*6+45=360+45=395 minutes due to that you add 60 minutes for every hour.
1200 is just noon, but that’s 12 hours, so we can convert that into minutes - 60*12=720
Finding the difference, we get
720
-395
_____ due to that -395=-400+5, so 720-400=320 and 320+5=325
325
Converting them back into hours, we get 325/60=5+25/60, which is 5 60 minute increments (5 hours) and 25 minutes, or 0525
Good luck, and feel free to ask any further questions!
Answers:
8. 12x+3= 27
move 3 to the other side , sign changes from +3 to -3
12x+3-3=27-3
12x= 24
divide by 12 for both sides
12x/12=24/12
x= 2
9. 6(y-10)=42
mutiply the bracket by 6
(6)(y)(6)(-10)= 6y-60
6y-60= 42
move -60 to the other side, sign changes from -60 to +60
6y-60+60=42+60
6y=102
divide by 6
6y/6=102/6
y=17
10. 9x-2=4x+13
move +4x to the other side
9x-4x-2= 4x-4x+13
5x-2= 13
5x-2+2= 13+2
5x= 15
divide by 5 for both sides
5x/5= 15/5
x= 3
11. 4/3y+5/2y= 1
find the common denominator for both of the fractions which is 6.
Mutiply by 2 for 4/3y .
4(2)/3(2)y=8/6y
Mutiply by 3 for 5/2y
5(3)/2(3y)= 15/6y
8/6y+15/6y= 23/6y
23/6y= 1
Mutiply both sides by 6/23
23/6y(6/23)= 1 (6/23)
Cross out 6 and 6 , divide by 6 and then becomes 1.
Cross out 23 and 23, divide by 23 and then becomes 1.
1*1*y=y
y= 6/23
To determine the minimum amount that Marian should pay for her credit card, multiply the new balance on her credit card with the percentage given. This is shown below.
m = ($148.73) x 0.12 = $17.8476
Thus, Marian's minimum payment is approximately $17.85.
Well, if earth's climate is getting warmer then the glaciers would probably start to melt. I'm not sure how to answer the second one either, maybe since glaciers are so big, they would be a lot of animals living on them and they would loose their habitat maybe causing them to have to move somewhere else?
