C. y=4 through isolating of the variable
Answer: her monthly allowance is $630
Step-by-step explanation:
Let x represent her monthly allowance.
Claire spent $450 of her allowance each month and saved the rest. This means that the amount she saved each month is x - 450
If she increased her spending by 18% her savings would decrease by 30%. The expression for an 18% increase in her spending would be
(18/100 × 450) + 450 = 81 + 450
= 531
The expression for a 30% decrease in her savings would be
(x - 45) - [30/100 × (x - 450)]
= (x - 45) - [0.3(x - 450)]
= (x - 45) - [0.3x - 135]
= x - 45 - 0.3x + 135
= x - 0.3x - 45 + 135
= 0.7x + 90
Therefore,
0.7x + 90 = 531
0.7x = 531 - 90
0.7x = 441
x = 441/0.7
x = $630

D. lie in the same plane.</span><span>
The definition of capillarity is that points are considered as co-planar when these points are on the same plane, so it is obvious that the answer D is true because this statement is the definition of capillarity. This is shown in Figure 1.

A. lie on the same line.</span><span>
If four points lie on the same line then there will be a plane that contains this line, therefore the definition is fulfilled. This is shown in Figure 2.
</span><em>Finally, the correct answers are A. and D.</em>
