If Bert had 3 cents more he would have twice as much as Georgia. If he had 4 cents less, he would have the same amount.

-10w - 400 = o

w= weeks
o = remaining balance

B. f(x)=-1/3x^4+7x^2+15. You can visualize the function using a graphing tool for better understanding.

The least number of times that two planes can cross is zero, since parallel planes do not intersect. A good example would be a floor and a ceiling, which run parallel, hence they do not meet. Conversely, if two planes occupy the same space, they can intersect at infinitely many points, as could happen with a line within that plane.

The provided number is 0.555, which can also be expressed as

In examining the digits post-decimal, each subsequent digit decreases to 1/10 of the preceding one.

Thus, the assertion that "the value of the 5 in the thousands place is ten times as great as the 5 in the hundredth place" is incorrect.

(a) For E based on d, the equation is E = 6500 - 50d (b) After 30 days, the remaining excess will be 5000.
