For example, think about 8.4 - 2.9.
You have to regroup because you can't subract 4 - 9.
4 turns into a 14 since you borrow from the left number, 8.
8 turns into a 7 after that.
Now, you have to subtract 14 - 9 and 7 - 2. You're answer is 5.5.
You can check your work by doing inverse opperations:
By adding:
5.5 + 2.9 = 8.4
Or by subracting 8.4 - 5.5 = 2.9
Hope this helped you! If you need a better explaination or another example, I will be happy to help you! :)
Yes, they are equivalent
6+7-5=8. -5+10+3=8
Take 60 minutes and times that by 60 to find your seconds. (s)
Next, take 240 times 3 to find your feet. (f)
Then, take your feet divided by seconds. (T)
f/s =T
Answer:
Following are the answer to this question:
Step-by-step explanation:
In the given-question, the information is missing. first, we declare the missing information, after that we define its solution:
Missing information:
plotting the Points (2, 0), (2, 4), (2, 1), and (2, -1).
solution:
please find the attachment.
In the given attachment file, all the points lie within the same line, which indicates its points, and the set may be interpreted throughout the form of (2,y), or even the points may also be placed on the line x=2.
Answer:
The price of the admission is 15.
Step-by-step explanation:
From the information given, you can write the following equations:
a+3e=45 (1)
a+5e=65 (2), where:
a is the admission cost
e is the exhibition cost
First, you can solve for a in (1):
a=45-3e (3)
Second, you can replace (3) in (2):
45-3e+5e=65
45+2e=65
2e=65-45
2e=20
e=20/2
e=10
Finally, you can replace the value of e in (3):
a=45-3e
a=45-3(10)
a=45-30
a=15
According to this, the price of the admission is 15.
