Answer:
[tex]74.1[/tex]$
Step-by-step explanation:
[tex] \frac{x}{57} = \frac{30}{100} [/tex]
[tex](x)100 = (30)57[/tex]
[tex](x)100 = 1710[/tex]
[tex] \frac{(x)100}{100} = \frac{1710}{100} [/tex]
[tex]x = \frac{1710}{100} [/tex]
[tex]x = 17.1[/tex]
[tex]57 + 17.1 = 74.1[/tex]

The product of two consecutive odd numbers equals 55 plus ten times the even number which is between them. Find the even number.
Answer:
14
Step-by-step explanation:
The product of two consecutive odd numbers equals 55 plus ten times the even number which is between them. Find the even number.
Let the two odd consecutive integer be x and x+2
Let the even number between then be x+1
If the product of two consecutive odd numbers equals 55 plus ten times the even number, then;
(x)(x+2) = 55 + 10(x+1)
Expand
x² + 2x = 55 + 10x + 10
x² -8x -65 = 0
x² - 13x+5x - 65 = 0
x(x-13)+5(x- 13) = 0
(x-13) (x+5) = 0
x = 13 and -5
Since the even number is x + 1
Even number = 13 + 1 = 14

Consider a student loan of $15,000 at a fixed APR of 6% for 25 years. a. Calculate the monthly payment. b. Determine the total amount paid over the term of the loan. c. Of the total amount paid, what percentage is paid toward the principal and what percentage is paid for interest.
9514 1404 393
Answer:
a) $96.65
b) $28,995
c) 51.7% to principal; 48.3% to interest
Step-by-step explanation:
a) The monthly payment is given by the amortization formula:
A = P(r/12)/(1 -(1 +r/12)^(-12t))
where P is the loan amount, r is the annual rate, and t is the number of years
Filling in the given values, we find ...
A = $15,000(0.06/12)/(1 - (1 +0.06/12)^(-12(25))) ≈ $96.65
The monthly payment is $96.65.
__
b) The 300 payments total ...
$96.65 × 300 = $28,995
The total amount paid is $28,995.
__
c) The percentage paid toward the principal is ...
$15,000/$28,995 × 100% ≈ 51.7%
The remainder is paid toward interest: 100% -51.7% = 48.3%
51.7% is paid toward principal, 48.3% is paid for interest.

$9.72. What is the cost per ounce?
A $0.18
C $4.32
B $1.80
D $524.88
I need help nowwwwww
Answer:
The correct answer would be "A"
Step-by-step explanation:
You would take the total cost and divide it by however many ounces are there. In this case, take 9.72 and divide by 54. There you get 0.18 cents per ounce. You can go back and check it, so multiply 54 by 0.18 and you get 9.72.

Select all of the equations that have a solution of 4.
A.5x=20
B.8x-32
C.-4x=16
D.x/2=2
E.x/4=16
Answer:
a and d
Step-by-step explanation:
5x = 20
5/5x = 20/5
x = 4
8x = -32
x = -4
-4x = 16
x = -4
x/2 = 2
2*x/2=2*2
x = 4
x/4 = 16
4*x/4 = 16*4
x = 64
The equations 5x = 20 and x/2 = 2 are that have a solution of 4 which is the correct answer would be options (A) and (D).
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
We have to determine the solution of all the given equations.
5x = 20
x = 20/5
Apply the division operation, and we get
x = 4
This is the required solution.
8x = -32
x = -32/8
Apply the division operation, and we get
x = -4
-4x = 16
x = 16/4
x = -4
x/2 = 2
2×x/2=2×2
x = 4
This is the required solution.
x/4 = 16
4×x/4 = 16×4
x = 64
Therefore, the correct answer would be options (A) and (D).

Express -5x(x+6) = 4(x-3)-10 in the form ax^2+bx+c=0 (quadratic formula)
Answer:
[tex]5x^{2} + 34x - 22[/tex]
Step-by-step explanation:
-5x ( x + 6 ) = 4 ( x - 3 ) - 10
Distribute
[tex]-5x^{2} - 30x = 4x - 12 - 10[/tex]
Simplify,
[tex]-5x^{2} -30x = 4x -22[/tex]
Inverse operations;
[tex]-5x^{2} - 30x = 4x - 22\\ +30x +30x\\\\-5x^{2} = 34x - 22\\+5x^{2} +5x^{2}\\\\5x^{2} + 34x - 22[/tex]
Answer:
5x^2 + 34x - 22 = 0
Step-by-step explanation:
-5x(x+6) = 4(x-3)-10
-5x^2 - 30x = 4x - 12- 10
-5x^2 - 30x - 4x + 22 = 0
-5x^2 - 34x + 22 = 0
