Answer:
7 , or 7/1
Step-by-step explanation:
Let ? = x. Set the equation:
(3/10)x = 21/10
Isolate the variable, x. Multiply 10/3 to both sides of the equation:
x * (3/10) * (10/3) = (21/10) * (10/3)
x = 21/10 * 10/3
Simplify the equation. Divide common factors from both the numerator and denominator, and then simplify:
x = (21 * 10)/(10 * 3)
x = (21/3) = 7/1 = 7
x = 7

Question 7 of 25 Which of the binomials below is a factor of this trinomial? x - 6x-16 O A. X-1 O B. X-8 OC. X-16 O D. x-2
Answer:
(x-8) is the factor.
Step-by-step explanation:
The given trinomial is [tex]x^{2}-6x-16[/tex].
We need to find the factor of this trinomial.
[tex]x^{2}-6x-16=x^2-8x+2x-16\\\\=x(x-8)+2(x-8)\\\\=(x+2)(x-8)[/tex]
The factors of [tex]x^{2}-6x-16[/tex] is (x-2) and (x-8).
So, the factor of [tex]x^{2}-6x-16[/tex] is (x-8). Hence, the correct option is (B).

Step-by-step explanation:
In a chemistry lab, acid and water are mixed in the ratio 1 : 5. A bottle contains 228 ml of the mixture. How much water were needed to make this amount of mixture?
Given that,
The ratio of acid and water is 1 : 5.
A bottle contains 228 ml of the mixture.
To find,
How much water were needed to make this amount of mixture.
Solution,
Let acid is x and water is 5x. ATQ,
x+5x = 228
6x = 228
x = 38
Acid = 38 mL
Water = 5x
= 5(38)
= 190 mL
Hence, 190 mL of water is needed.

Answer:
205
Step-by-step explanation:
Answer: 2.05 dollars
=================================================
Work Shown:
1 quarter = 25 cents
5 quarters = 125 cents .... multiply both sides by 5
1 dime = 10 cents
8 dimes = 80 cents .... multiply both sides by 8
(5 quarters) + (8 dimes) = (125 cents) + (80 cents) = 205 cents
205 cents = 205/100 = 2.05 dollars
-------------------------
Another way to approach the problem is to compute
5*25 + 8*10 = 205
that's the total number of cents

A credit card company charges a 3.5% transfer fee to transfer a balance to a new account. What would the transfer fee be for a balance transfer of $7,500?
Answer:
$262.5
Step-by-step explanation:
We are told that:
A credit card company charges a 3.5% transfer fee to transfer a balance to a new account.
The transfer fee be for a balance transfer of $7,500 is calculated as:
3.5% × $7500
= 3.5/100 × $7500
= $262.5
The transfer fee for a balance transfer of $7500 is $262.5

Part A: Marguerite rented a truck at $125 for 2 days. If she rents the same truck for 5 days, she has to pay a total rent of $275.

(4 points) Part B: Write the equation obtained in Part A using function notation. (2 points) Part C: Describe the steps to graph the equation obtained above on the coordinate axes.

Part B: Write the equation obtained in Part A using function notation. (2 points)
Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals. (4 points)
(10 points)
Answer:
:)
Step-by-step explanation:
Part A: To get an equation into standard form to represent the total amount rented (y) that Marguerite has to pay for renting the truck for x amount of days, we use the formula for the equation of a straight line.
Remember that the equation of a straight line passing through points is ( x_{1} , y_{1} ) and the points ( x_{2} , y_{2} ) is given by
y - y_{1} / x - x_{1} = y - y_{2} / x - x_{2}
Knowing that Marguerite rented a truck at $125 for 2 days, we know if she rents the exact same truck for 5 days, she has to pay a total of $275 for the rent.
This means that the line modeling this situation crosses points at (2, 125) and (5, 275).
The equation modeling the total rent (y) that Marguerite has to pay for renting the truck for x days is given by
y - 125 / x - 2 = 275 - 125 / 5 - 2 = 150 / 3 = 50
But if you are writing the equation in standard form it would be
50x - y = -25
Part B:
When writing the function using function notation it means you are making y the subject of the formula and then replacing the y with f(x).
If you remember that from part A, we have that the equation for the total rent which is y that Marguerite has to pay for renting the truck for x amount of days is given by
y = 50x + 25.
Writing the equation using the function notation would give us this
f(x) = 50x + 25
Part C:
To graph the function, we name the x-axis the number of days and name the y-axis total rent. The x-axis is numbered using the intervals of 1 while the y-axis is numbered using the intervals of 50.
The points of (2,125) and of (5,275) are marked on the coordinate axis and a straight line is drawn to pass through these two points.

6v+18-9v=-12
solve for v.
Answer:
v = 10
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
6v + 18 - 9v = -12
Step 2: Solve for v
Combine like terms: -3v + 18 = -12Isolate v term: -3v = -30Isolate v: v = 10Step 3: Check
Plug in v into the original equation to verify it's a solution.
Substitute in v: 6(10) + 18 - 9(10) = -12Multiply: 60 + 18 - 90 = -12Add: 78 - 90 = -12Subtract: -12 = -12Here we see that -12 does indeed equal -12.
∴ v = 10 is the solution to the equation.
