I believe the answer is C.
93.53 - 21.41 = 72.12
If you simplify C, its answer becomes equivalent to the answer of the original problem:
(90 - 20) + (3 - 1) + (0.5 - 0.4) + (0.03 - 0.01)
70 + 2 + 0.1 + 0.02
72.12
Answer:
7
Step-by-step explanation:
7 is approximate to 
because 7 is 
, and 49 is close to 47
Yes the quotient of 9 is rational
Answer:
45 does not go into 285 evenly
The quotient contains a repeating decimal
The quotient is 6.3
Step-by-step explanation:
285/45 = 6.33333333
6.33333333 = 6.3
1) let both have x ,
so putting in eqn ;
4x+0.50 = 9x-3
5x=2.50
x=0.50
therefore both have 50 p in the beginning !!
2) let the number be x
so in eqn;
(x+18)/2=5x
x+18=10x
9x=18
x=2
so the number must be 2 !!
if you have still any problem, comment !!
