Answer:
I. First number, a = 40.
II. Second number, b = 50.
III. Third number, c = 120.
Step-by-step explanation:
Let the three numbers be a, b and c respectively.
Given the following data;
Translating the word problem into an algebraic equation, we have;
a + b + c = 210
b = a + 10
c = 3a
Substituting the value of b and c into the equation, we have;
a + a + 10 + 3a = 210
5a + 10 = 210
5a = 210 - 10
5a = 200
a = 200/5
a = 40
To find the value of b;
b = a + 10
b = 40 + 10
b = 50
To find c
c = 3a
c = 3*40
c = 120

Find the solution of this system of equations.
Separate the x- and y-values with a comma.
X + 2y = 8
x - y = 2
Answer:
Step-by-step explanation:
x + 2y = 8
x - y = 2
x + 2y = 8
-x + y = -2
3y = 6
y = 2
x - 2 = 2
x = 4

Given the function g(x) = -3x + 4, compare and contrast g(-2) and g(4). Choose the statement that is true concerning these two values.
Answer: D
Step-by-step explanation:
Fill in the x's with -2 for the first time to get one answer then go back and fill in 4 for the second answer.
g(-2)= 10
g(4)=-8
Proving g(-2) is greater than g(4).

What type of symmetry does the figure have?
line symmetry only
rotational symmetry only
both line and rotational symmetry
none of the above
Answer:
B. rotational symmetry onlyStep-by-step explanation:
Line symmetry is when the line acts like a mirror. We don't have such a symmetry here.
The figure has rotational symmetry only, if you rotate it about its center it will map to itself every 180 degrees.
Correct option is B
Answer:
B. rotational symmetry only

The polynomial ax2 − 64 is a difference of two squares. Find all possible values of a between 1 and 100 inclusive. The inclusive values are
Answer:
[tex]a = \{1,4,9,16,25,36,49,64,81,100\}[/tex]
Step-by-step explanation:
Given
[tex]ax^2 - 64[/tex]
Required
Determine possible values of a
For the expression to be a difference of two squares, then a must be a perfect square between 1 and 100 (inclusive).
Let [tex]a = k^2[/tex] where [tex]k \ge 1[/tex]
When k = 1
[tex]a = 1^2 = 1[/tex]
k = 2
[tex]a = 2^2 = 4[/tex]
k=3
[tex]a = 3^2 = 9[/tex]
It goes on until k = 10
[tex]a = 10^2 = 100[/tex]
So, the possible values of a are:
[tex]a = \{1,4,9,16,25,36,49,64,81,100\}[/tex]

The Sugar Sweet Company is going to transport its sugar to market. It will cost $3500 to rent trucks plus $250 for each ton of sugar
transported. The total cost, C (in dollars), for transporting n tons is given by the following.
C = 3500+ 250n
What is the total cost of transporting 15 tons?
In the total cost is $8750, how many tons is the company transporting?
Answer: Equation relating C to S :
The total cost to transport 19 tons of sugar is $11, 250.
Step-by-step explanation:
Given : It will cost $6500 to rent trucks, and it will cost an additional $250 for each ton of sugar transported.
Total cost = $6500 + $250 x (amount of sugar transported ( in tons))
Let C represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported.
Then, the equation relating C to S would be :
When S= 19 , we get
Hence, the total cost to transport 19 tons of sugar would be $11, 250.
