Answer:

125/2 or 62.5 or 62 1/2 (x=)

Step-by-step explanation:

25/4=x/10 multiply everything by 20

25*20/4=20x/10 simplify

25*5=2x simplify

125=2x divide on both sides

125/2 or 62.5 or 62 1/2=x

0=-20.5x+16.35x-0.1245

Pachacha [2.7K]

The value of x in the given equation $-20.5x+16.35x -0.1245 = 0\\$ is 0.03

Step-by-step explanation:

The given equation is that $-20.5x+16.35x -0.1245 = 0\\$

The steps to be followed to solve the equation are :

Add the like terms together to reduce the equation in a simplified form.

Here, there are two x terms and they must be reduced to a single term.

For this, add the both terms together so that the equation is simplified into one x term and a constant term.

⇒ $(-20.5x+16.35x) - 0.1245 = 0$

⇒ $4.15x-0.1245 = 0$

To eliminate the constant term on the left side of the equation, add 0.1245 on both sides.

⇒ $4.15x -0.1245+0.1245 = 0.1245$

⇒ $4.15x = 0.1245$

Now, the equation is further simplified by dividing 4.15 on both sides,

⇒ $4.15x / 4.15 = 0.1245/4.15$

⇒ $x = 0.03$

Therefore, the value of x is 0.03

Two accounts earn simple interest. The balance y (in dollars) of Account A after x years can be modeled by y=10x 500. Account B

12345 [234]

In an installment loan, a lender loans a borrower a principal amount P, on which the borrower will pay a yearly interest rate of i (as a fraction, e.g. a rate of 6% would correspond to i=0.06) for n years. The borrower pays a fixed amount M to the lender q times per year. At the end of the n years, the last payment by the borrower pays off the loan.

After k payments, the amount A still owed is

A = P(1+[i/q])k - Mq([1+(i/q)]k-1)/i, = (P-Mq/i)(1+[i/q])k + Mq/i. The amount of the fixed payment is determined byM = Pi/[q(1-[1+(i/q)]-nq)]. The amount of principal that can be paid off in n years isP = M(1-[1+(i/q)]-nq)q/i. The number of years needed to pay off the loan isn = -log(1-[Pi/(Mq)])/(q log[1+(i/q)]). The total amount paid by the borrower is Mnq, and the total amount of interest paid isI = Mnq - P.

Austin bought 5 pairs of jeans and 2 shirts for $166. Travis bought 3 pairs of jeans and 4 shirts for $164 at the same store. Ho

OLEGan [10]

Answer:

pair of jeans = 21

shirt = 30.5

Step-by-step explanation:

Let the cost of each pair of jeans be $ x, and the cost of each shirt be $ y.

Since, cost of each pair of jeans is $ x, the cost of 5 pair of jeans will be $ 5x and cost of 2 shirts will be $ 2x.

Likewise, the cost of each pair of jeans is $ x, so the cost of 3 pair of jeans will be $ 3x and cost of 4 shirts will be $ 4y.

5 pair of jeans and 2 shirts for $166. This means:

Equation 1: 5x + 2y = 166

3 pair of jeans and 4 shirts for $164. This means:

2x + 4y = 164

Dividing both sides by 2, we get:

Equation 2: x + 2y = 82

Subtracting Equation 2 from Equation 1, we get:

5x + 2y - (x + 2y) = 166 - 82

5x + 2y - x - 2y = 84

4x = 84

y = 30.5

Using the value of x, in Equation 2, we get:

21 + 2y = 82

2y = 61

y = 30.5

Since, x represents the cost of pair of jeans, the cost of each shirt is $ 16.

y represents the cost of sweater, so the cost of each sweater is $ 33.
