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.
Answers
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

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?
Answers
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

This is a help site, so I'll explain each property and see if you can match them yourself.
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.
