We have to determine the number of blocks. We know that that number have 9 in the ones place. It also has the number in the hudreds place ( x ) which is 1 more than the number in the tens place ( y ). And: x + y = 11. Another equation is: x = y + 1. Therefore y + 1 + y = 11; 2 y = 11 - 1; 2 y = 10; y = 10 : 2; y = 5 and x = 5 + 1 = 6. Answer: There are 659 blocks<span>.</span>

Sometimes the best way to tell whether two variables are associated is to ask yourself whether they are not associated. Think backward. In a two-way frequency table, if the relative frequencies for one variable are the same (or close) for all categories of another variable, there is no (or little) association.
Answer:
x + 3y = 3
Step-by-step explanation:
The standard form equation ...
ax +by = c
has slope -a/b. Here, we want -a/b = -1/3, and we want a > 0. We can choose ...
a = 1, b = 3
and we can find the constant c using the given point.
x +3y = 12 +3(-3) = 3
The desired standard-form equation is ...
x + 3y = 3
If it is a negative power, you do the reciprocal. so it would be 1/49^1/2
1/2 power means find the square root.
the final answer would be 1/7
