Answer:
30 per hour
Step-by-step explanation:
you need to divide the crates by the hour
X+y=15
2x+3y=37
15-x=y
2x+3(15-x)=37
2x+(45-3x)=37
2x-3x+45=37
-1x=-8
x=8
x is the amount of bikes, so there are 8 bikes. 8x2=16.
37-16=21
21/3=7
There are 7 tricycles.
376.64-109.38=267.26
The tenth place is the first number after the decimal. 5 and up make the number in front go up. Since we have a 6 here, the 2 goes to 3.
267.26 rounded to the nearest tenth is 267.3

Associative property of addition is used when you want to group addends.
This is mainly used to cluster set of numbers or in this case, addends. How do
you use the associative property when you break apart addends? Simple you group
them using the open and closed parentheses or brackets. Take for an example 1 +
1 + 2 = 4. Using the associative property you can have either (1 + 1) + 2 = 4
or 1 + (1 + 2) = 4 clustered into place.
Seems to me like the question is: What are the two numbers ?
They have to multiply to 2,800 .
It's fairly easy to find two numbers that do that, BUT ...
they're not supposed to be multiples of 10 .
1 x 2,800 = 2,800 . . . . . No good. 2,800 is a multiple of 10 .
2 x 1,400 = 2,800 . . . . . No good. 1,400 is a multiple of 10 .
4 x 700 = 2,800 . . . . . No good. 700 is a multiple of 10 .
5 x 560 = 2,800 . . . . . No good. 560 is a multiple of 10 .
7 x 400 = 2,800 . . . . . No good. 400 is a multiple of 10 .
8 x 350 = 2,800 . . . . . No good. 350 is a multiple of 10 .
10 x 280 = 2,800 . . . . . No good. 280 is a multiple of 10 .
14 x 200 = 2,800 . . . . . No good. 200 is a multiple of 10 .
16 x 175 = 2,800 . . . . . Finally ! Neither one is a multiple of 10 .
