George has cut down a 60ft high oak tree. He now wants to chop it into smaller pieces. He first cuts it into two pieces that are both 30ft. And then he continues on into making ten pieces that all are 6ft long before loading them onto his truck.

By looking at the different pieces of wood we can see that the following holds true.
60=30+30=6+6+6+6+6+6+6+6+6+6
This is called the reflexive property of equality and tells us that any quantity is equal to itself
a=a
We can also use this example with the pieces of wood to explain the symmetric property of equality. This property states that if quantity a equals quantity b, then b equals a.
ifa=b,thenb=a
Or if we use our example
if60=30+30,then30+30=60
Another property that can be explained by this is the transitive property of equality. It tells us that if a quantity a equals quantity b, and b equals the quantity, c, then a and c are equal as well.
ifa=bandb=c,thena=c
Or in the numbers taken from the oak tree example
if60=30+30
and30+30=6+6+6+6+6+6+6+6+6+6
then60=6+6+6+6+6+6+6+6+6+6
Since we know that 30 + 30 = 20 + 40 and that 30 + 30 = 60 we can substitute 30 + 30 for 20 + 40 and get 60 = 20 + 40. This is called the substitution property of equality.
If a = b, then a can be substituted for b in any expression.George has cut down a 60ft high oak tree. He now wants to chop it into smaller pieces. He first cuts it into two pieces that are both 30ft.

Guillermo bought some reams of paper for $10 each and a $100 printer. He spent a total of $450. Write and solve an equation to find the number of reams of paper Guillermo purchased.
Answer:
x = amount of paper
10x + 100 = 450
10x = 350
x = 35

A triangle has a perimeter of 15 feet. Side B is one foot longer than side A. Side C is two feet longer than side A. What is the length of each side.
Answer:
Side A = 4
Side B = 5
Side C = 6
Step-by-step explanation:
In the following equation, variable a is the length of Side A
a + (a + 1) + (a + 2) = 15
a + a + a + 1 + 2 = 15
3a + 3 = 15
- 3 - 3
3a (÷ 3) = 12 (÷ 3)
a = 4
Side A = 4
Side B = (a + 1) = (4 + 1) = 5
Side C = (a + 2) = (4 + 2) = 6
Choose the expression that represents a quadratic expression.
O 6x4 - 5x3 + 3x2 -7x - 8
) 5x3 + 3x2 -7x - 8
O 2x2 + 3x - 1
. 3x - 1
Answer:
3) 2[tex]x^{2}[/tex] + 3x - 1
Step-by-step explanation:
A quadratic expression is an expression involving a squared term
It can be written as y = a[tex]x^{2}[/tex] + bx + c, where a ≠ 0
// note that here b and c can be equal to 0
1) 6[tex]x^{4}[/tex] - 5[tex]x^{3}[/tex] + 3[tex]x^{2}[/tex] - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a quartic function, since the unknown variable x in forth degree. It can be written as y = a[tex]x^{4}[/tex] +b[tex]x^{3}[/tex] +c[tex]x^{2}[/tex] + dx + e, where a before [tex]x^{4}[/tex] ≠ 0
2) 5[tex]x^{3}[/tex] + 3[tex]x^{2}[/tex] - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a cubic function, since the unknown variable x in third degree.
3) 2[tex]x^{2}[/tex] + 3x - 1 is correct
4) 3x - 1 is incorrect because there is no squared term. You could also say that here a = 0 and write it as y = 0 * [tex]x^{2}[/tex] + 3x - 1. It is also called a linear function because if you'd draw a graph, it would be a line

A tank that holds up 10 gallons. when its active, a drain empties water from the tank at a constant rate, when Jada first see the tank, it contains 7 gallons of water. three minute later the tank contains five gallons of water.
At what constant/rate is the amount of water changing in the tank?
Answer:
-2/3 gallon/minute
Step-by-step explanation:
In three minutes the water volume has decreased by 2 gallons (7 less 5 is 2). The unit rate of decrease of the amount of water in the tank is thus:
- 2 gallons
------------------- = -2/3 gallon/minute

The following table shows the number of fire hydrants in each neighborhood overseen by Fire District 9
Answer:
15
Step-by-step explanation:
The median, is just the middle number in a set of numbers.
In this case, our set is: 17, 8, 15, 21, 12.
However, the set must be in increasing order, so the set becomes: 8, 12, 15, 17, 21.
This gives us the median, which is the middle number, to be: 15.

a=-b+5
2b+a=11
Answer:
a = -1
b = 6
Step-by-step explanation:
a = -b + 5
2b + a = 11
2b + a = 11
2b + (-b + 5) = 11
2b - b + 5 = 11
b + 5 = 11
b = 11 - 5
b = 6
2b + a = 11
2(6) + a = 11
12 + a = 11
a = 11 - 12
a = -1

Solve the following equation: 4(x + 2) - 17 = 35
A: -11
B: 25/2
C: 15
D: 11
Answer:
D: 11
Step-by-step explanation:
4(x + 2) - 17 = 35
4x+8 - 17=35
4x-9=35
4x=35+9=44
x=44/4=11
