They will have same money after 10 weeks.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Brian has $45.25 saved and earns $7.25/week. Dakota has $25.25 saved and earns $9.75/week.
Let the number of weeks be x.
Now, money earned by Brain x weeks is 45.25+7.25x
Money earned by Dakota x weeks is
25.25+9.75x
Now, 45.25+7.25x=25.25+9.75x
2x=20
x=10
Therefore, they will have same money after 10 weeks.

What is the longest time difference that can be found on the map (consider standard time only)? Give the locations and the time zones involved.
72. |x - 3x5| = 6 + y
|9-y + 6| =21
In the equations above, y<0. Which of the following could be the value of x?
Answer:
Step-by-step explanation:
|x-3x^5|=6+y
y<0
|9-y+6|=21
|15-y|=21
15-y±21
either 15-y=21
-y=6
y=-6
or 15-y=-21
y=36
but y<0
so y=-6
|x-3x^5|=6+y
|x-3x^5|=6-6
|x-3x^5|=0
x-3x^5=0
x(1-3x^4)=0
either x=0
or 1-3x^4=0
or (1-√3 x²)(1+√3x²)=0
1-√3 x²=0
x²=1/√3
x=±√(1/√3)
x²=-1/√3
x=±(1/√3)i

Find the 14th term of the geometric sequence below. Leave your answer in fraction form if necessary.
64,-32,16,-8
Step-by-step explanation:
First term (a) = 64 = t1
Second term (t2) = -32
Common ratio (r) = t2/ t1 = -32 / 64 = - 1/2
Now
Tn =
[tex]a {r}^{n - 1} [/tex]
[tex]t14 = 64 \: ( - \frac{1}{2}) ^{14 - 1} [/tex]
[tex] = 64 \: ( - \frac{1}{2} ) {}^{13} [/tex]
= - 64 * 1 / 8192
= - 1/128

50 POINTS!!! Word problem.
A class contributed $8.40 in dimes and quarters to the Red Cross. In all, there was 45 coins. How many coins of each kind were there?
Please also give an explanation. 50 points are a big deal.
Answer:
Step-by-step explanation:
Let d = # of dimes
Let q = # of quarters
45 = d + q
.1d + .25q = 8.40
Then we can use the substitution method and make it so that d = 45 - q.
Then plug in the value for d into the second equation.
.1(45-q)+.25(q)=8.40
4.5-.1q+.25q=8.40
4.5+.15q = 8.40
.15q = 3.90
q = 26
d = 45 - 26 = 19
26 quarters
19 dimes

Associative property of addition, you can add 3 or more different numbers any which way, the sum will be the same.
Commutative Property of Addition - same as the associative property but with 2 numbers.
Identity Property of Multiplication - Any number multiplied by one is itself
Multiplicative Property of Zero: x * 0 = 0
Associative Property of Multiplication - Same as that of addition, yet with multiplication.
Distributive Property: Factoring Out.
EX: (12 x 15) = 3(4 x 5)
