Answer:

To regroup the sum, we need to first break them in tens and ones and then regroup them according to their place values.

Given sum:- 64+43, where 64 can be written as 60+4 and 43 can be written as 40+3, now regroup tens and ones particularly , we get

64+43

=60+4+40+3 [breaking]

=60+40+4+3 [combine according to the corresponding place values ]

=(60+40)+(4+3) [put parenthesis]

=100+7=107

64 + 43 = 107
107 - 43 = 64
107 - 64 = 43

they will each receive $1.75

Step-by-step explanation:

5.50*5= 27.50

5(3+t)-3(t+1) I don't understand how to do this problem.
shtirl [24]
Okay, just break it up so you're not overwhelming yourself or anything :)
So here, do it in steps-

Let's do 5(3 + t) first:
Distribute the 5, or in non-mathematical terms, just multiply 5 by 3 and t. This will give you 15 + 5t.

Now onto -3(t + 1):
Again, just multiply -3 by t and 1. This will come out to: -3t - 3.

*Note: the 3 is negative because it's "MINUS 3" in the original equation and remember that any number times a negative, if it isn't negative itself, will turn out to be negative.... (aka "-" x "-" = "+" | "+" x "+" = "+" | "-" x "+" = "-")*

ANYWAY
Now just put both answer together and you get:
15 + 5t -3t - 3. You can only add and minus the LIKETERMS (which are the things that are the same) - in this case, the liketerms are 15 and -3 ,,,, AND 5t and -3t.

15 - 3 = 12
5t - 3t = 2t

12 + 2t is your final answer. Hope that helps! :)
