which least number should be subtracted from 1000 so that 30 divides the difference exactly
.3x=30%of x When x=the number you are taking the percentage of
The number is negative 852.
-30 and -30

40 (30 must be 3/4 of orig number so (30/3)*4) pls give explanation?
Algebraic factorization of 30a3b2 = 30 x a x a x a x b x b
The same as linear growth, e.g. start with 30 hats, buy 3 new ones each year. There is algebraic/linear growth of the number of hats through the years
3 represents the number 30, it is also in the tens place
You said that " 7x - 4x = 30 ".From only that much information, I can see that 3x must be 30,which leads me directly to the realization that 'x' is 10 .
XXL is a clothing size, not a number. You've probably transposed it from LXX, which is 50 + 10 + 10 = 70. If it were a number, it would be XX = 20 before (therefore subtracted from) V, which is 50, making 30. As XXX is commonly understood to be 30, then there's no advantage in less numerals used with XXL - so it is kept purely for sizing clothes.
36 The number of neutrons is the mass number (the 66) minus the atomic number (which is 30 for zinc and represents the number of protons).
30. 20--10, two-'s equals +. 20+10=30
Zn represents ZINC, having atomic number 30 and mass number 65.39.
The Roman numeral LXXXI represents the number 8150 + 30 + 1 = 81
Let x = your number;( 3 x ) - 24The 3x portion represents three times a number, then you subtract (24 less) the 24.
