Answers

2a 49.73
Bc 4973\100=49.73
1b 30.4
Bc 3040/100=30.4
3b73.03
Bc 730.3/10=73.03
4b 100
Bc 2820/28.2=100
2a is 49.73
1b is 30.4
3b is 73.03
4b is 100

for these problems you move the decimal to the right for the end answer depending on how many 0’s are in the number you’re multiplying by. for example, 100•__=3040. you would move the 3040 two decimals to the left since there are two 0s in 100, making the answer 30.4

ooh fun

so xyz=number
z=2x
x+y+z=14
subsitute z=2x into x+y+z=14
x+y+(2x)=14
3x+y=14
number must be 3 digit and less thaan 500
since the tens digit's max is 9 then
z+x≥14-9
z=2x
3x≥5
x max=5 because 500 is max so 
x could be 2,3,4 so 

284
356
428
are the numbers
