Sarah needs an additional monthly income of $1125.77 to pay off her credit card in 9 months.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Using the information given,

We can find the current monthly payment Sarah is making using the formula for the present value of an annuity:

[tex]PMT = PV \times r \times (1 + r)^n / [(1 + r)^{n - 1}][/tex]

where PV is the present value (balance), r is the monthly interest rate (APR/12), and n is the number of months (36).

PMT.

[tex]= 9450 \times 0.17/12 \times (1 + 0.17/12)^{36} / [(1 + 0.17/12)^{36} - 1][/tex]

= $338.48

To pay off the balance in 9 months, Sarah needs to increase her monthly payment.

Let's call this additional payment x.

Then, we have:

[tex]9450 \times 1.17^{9/12} = (338.48 + x) \times ((1 + 0.17/12)^{9 - 1}) / (0.17/12)\\[/tex]

Solving for x, we get:

x = $1125.77

Therefore,

Sarah needs an additional monthly income of $1125.77 to pay off her credit card in 9 months.

Answer: $116.15

Step-by-step explanation:

We first would start with the last  thing, the $38.50 Lisa has left! From reading the word problem, we can tell that she had another $38.50 she spent on a radio.She spends $7.20 (ring) + $1.95 (battery) before this and gives her mom $30.

All of these are subtractions from the initial amount:

x - 1.95 - 30.00 - 7.20 - 38.50 = 38.50

x - 77.65 = 38.50

x = $116.15

Answer:

length = 12

width = 9

Step-by-step explanation:

Let w= width of rectangle

length = w + 3

2w + 2(w + 3) = 42

2w + 2w + 6 = 42

4w = 36

w = 9 ( width of rectangle)

width = 9 inches

length = 9 + 3 = 12 inches

The domain of a function is the set of possible input value, the function can take.

The domain is [0,10]

The given parameters are:

[tex]Flat\ Fee = 15.25[/tex]

[tex]Rate = 3.45[/tex]

So, the function f(x) is:

[tex]f(x) = Flat\ Fee + Rate \times x[/tex]

[tex]f(x) = 15.25 + 3.45 \times x[/tex]

[tex]f(x) = 15.25 + 3.45x[/tex]

Because x represents the number of orders, the value of x cannot be negative.

The teacher budgets $49.75.

This means that: f(x) = 49.75

So, we have:

[tex]49.75 = 15.25 + 3.45x[/tex]

Collect like terms

[tex]49.75 - 15.25 = 3.45x[/tex]

[tex]34.5 = 3.45x[/tex]

Divide both sides by 3.45

[tex]10 = x[/tex]

Rewrite as

[tex]x = 10[/tex]

Hence, the domain is [0,10]

Answer:

58 degree

Step-by-step explanation:

the total degree of the three interior angles together of a triangle = 180

here 2 sides are given so to find the 3rd angle we can just add the other 2 angles and subtract it from 180

so it'll be

[tex]65 + 57 = 122[/tex]

[tex]180 - 122 = 58 \: degrees[/tex]

Answer:

4.5

Step-by-step explanation:

Use a proportion.

3 3/8 = 3.375

9 inch is to 12 hours as 3.75 inches is to x hours.

9/12 = 3.375/x

3/4 = 3.375/x

3x = 4 * 3.375

x = 4 * 1.125

x = 4.5

Answer: 4.5 hours

Using rate if a 9-inch candle burns down in 12 hours, the amount of hours  it have burned 3 ³/₈ inches is 4 ¹/₂ h

Rate is the amount per unit time of a substance

Since a 9-inch candle burns down in 12 hours. To determine after how many hours will it have burned 3 ³/₈ inches, we proceed as follows.

.

First, we calculate the rate at which it burns which is given as r = Length of candle/time

Since

Substituting the values of the variables into the equation, we have that

r = Length of candle/time

r = 9 in/12 h

r = 3/4 in/h

To determine how many hours it would have burned 3 ³/₈ in, we have that

rate, r = Length/time

time = Length/rate

Since

Substituting the values of the variables into the equation, we have that

time = Length/rate

= 27 in/8 ÷ 3/4 in/h

= 27/8 in × 4/3 h/in

= 9/2 h

= 4 ¹/₂ h

So, it will have burned for 4 ¹/₂ h

Answer:

SF = 2/5

Step-by-step explanation:

The side on figure A which has the 10 is between angles with one mark and 2

The side on figure B which has the 4 is between angles with one mark and 2

The scale factor is what we multiply 10 by to get 4

10 * SF = 4

Divide each side by 10

10 * SF /10= 4/1-

SF = 4/10

SF = 2/5
