We are asked to solve for a number such that:

Twice that number plus 4 equals 6

Which can be written in math terms as:

2 x + 4 = 6

Now we proceed to isolate the unknown in steps.

First we subtract 4 from both sides:

2 x + 4 - 4 = 6 + 4

we combine like terms:

2 x = 10

Now we divide both sides by 2 so as to cancel the factor 2 that accompanies "x":

2 x / 2 = 10/ 2

perform the indicated operations:

x = 5

Bill's projected monthly payment under the Monthly Payments for Long-Term Loans using the Rule of Thumb is $870.00.

Bill's exact monthly payment using the Monthly Payments calculation is $933.36.

The real monthly payment is approximately $63.36 more than the predicted cost.

Simple procedures may be used to calculate the Monthly Payments for Long-Term Loans Rule of Thumb.

To begin, divide the annual percentage rate (APR) by 12 to obtain the monthly percentage rate (MPR).

Second, calculate the MPR on the principal amount. The product is the estimated monthly payment, which is similar to the real monthly payment and was computed using a financial calculator below.

Estimated Monthly Payment:

Home Mortgage = $116,000

Term of loan = 30 years

APR = 9%

Monthly interest rate = 0.0075 (0.09/12)

Estimated monthly payment based on the Monthly Payments for Long-Term Loans Rule of Thumb

($116,000 x 0.0075) = $870

Actual Monthly Payment Formula:

N (# of periods) = 360 months (30 x 12)

I/Y (Interest per year) = 9%

PV (Present Value) = $116,000

FV (Future Value) = $0

The outcome is given as:

PMT = $-933.36

Sum of all periodic payments = $-336,010.40

Total Interest = $220,010.40

Actual monthly payment =  $933.36

Estimated monthly payment 870.00

Difference = $63.36

Answer:

  (a) ∠e +∠d = 180°  is false

Step-by-step explanation:

You want to know which angle expression is not true.

We can figure the measures of all of the unknown angles, then check the given expressions.

Angles 'a' and 130° are corresponding angles, so congruent:

  a = 130°

Angles 'a' and 'e' are vertical angles, so congruent:

  e = a = 130°

Angle 'd' and 62° are vertical angles, so congruent:

  d = 62°

Angles 'b' and 'd' are corresponding angles, so congruent:

  b = d = 62°

Angles 'f' and 62° are corresponding angles, so congruent:

  f = 62°

Angles 'c' and 130° are a linear pair, so supplementary:

  c + 130° = 180°

  c = 50° . . . . . . subtract 130°

(a) ∠e +∠d = 180°   ⇒   130° +62° = 180° . . . . false

(b) ∠d +∠b = 124°   ⇒   62° +62° = 124° . . . . true

(c) ∠a +∠c = 180°   ⇒   130° +50° = 180° . . . . true

(d) ∠ 180° -∠f = 118°   ⇒   180° -62° = 118° . . . . true

Lenght of a rectangle: L

Widht of the rectangle: W

Perimeter of the rectangle: P

length of a rectangle is four times it's width: L = 4W

Perimeter is at most 106: P <= 106

Perimeter is 2L + 2W: P = 2L + 2W

P <= 106

if we use the value of P = 2L + 2W, we can write:

2L + 2W <= 106

Since L = 4W, then we can write this equation:

2L + 2W <= 106

2(4W) + 2W <= 106

8W + 2W <= 106

10W <= 106

W <= 106/10 = 10.6

W <= 10.6

Therefore, the greatest possible value for the width is 10.6

he TLAST OPTION is correct.

Answer:

Let width of rectangle be x cm.

Width = x cm

Length = 4x cm

Area of rectangle = length x width

4x × x = 144

4x² = 144

x² = 144 ÷ 4 = 36

x = √36 = 6

Width = 6 cm

Length = 6 × 4 = 24cm

Perimeter = 6 + 24 + 6 + 24 = 60 cm

Answer:

  c.  3

Step-by-step explanation:

You want to know the limit of the composite function f(f(x)) as x approaches zero.

The function f(x) can be evaluated at x=0. The graph shows the value to be ...

  f(0) = 2

The function f(x) can also be evaluated at x=2. The graph shows the value to be ...

  f(2) ≈ 3

The nearest value to f(f(0)) is 3.

Additional comment

For a continuous function, the limit at a point is simply the value at that point. F(x) is continuous in the neighborhoods of the points of interest, so we simply need to find the function value.

The number of chips and drinks are 46 chips and 56 drinks respectively.

Let the number of drinks be d.

Let the number of chips be c.

From the information, he works at a football concession stand selling drinks for $2 and bags of chips for $3 and he makes a total of $246 and sells a total of 100 drinks and bags of chips.

This will be:

c + d = 100 ........ i

2d + 3c = 246 ........ ii

From equation i, c = 100 - d

Substitute this into equation ii

2d + 3c = 246

2d + 3(100 - d) = 246

2d + 300 - 3d = 246

Collect like terms

2d - 3d = 246 - 300

-d = -54

d = 54

Number of drinks = 54

Since c + d = 100

c + 54 = 100

c = 100 - 54 = 46

Answer:

to solve for x, you gotta make the two equations equal to each other then you can move the numbers to get the value of x

20x+10=30x-10

20x-30x=-10-10

-10x=-20

x=2

Answer:

x=2

Step-by-step explanation:

if m/A and m/B are equal, to find x, your equation would be 20x+10=30x-10. doing two step equations, you would substract 20x from both sides, making your equation look like 10=10x-10. then you would add 10 from both sides making your equation 20=10x. then you would divide 10x from both sides making x=2.

there is no proportional relationship between the two qualities

For two quantities to be proportional, it must follow the formula:

y = kx

where k = proiportionality constant

k = y/x

if y = 950, x = 1

inserting in the equation:

950= 1k

k = 950

The equation becomes: y = 950 × x

We check for other values. if k is the same, it is proportional

when y = 2852, x = 3

2852 = k × 3

k = 2852/3 = 950.67

when y = 5.1, x = 4845

4845 = k × 5.1

k = 4845/5.1 = 950

From the above, the value of k which is different is for the 2nd value.

Since they are not all the same, we say there is no proportional relationship between the two qualities

Using the  sinking fund formula, the monthly payment needed to accumulate 270,000 with 5% interest or combine did monthly for 28 years, the monthly invested payment is 369.65.

A sinking fund, also referred to as a sinking fund, is defined by its name. Fundamentally speaking, it is built to sink. Although there are some similarities between a sinking fund and a reserve fund, their purposes differ significantly. Unlike reserve funds, which typically serve no particular purpose, sinking funds have a designated purpose.

Simply put, a reserve fund is a company's method of saving its surplus funds. There are numerous uses for reserve funds. They can be applied to a variety of costs, including those related to emergency situations, asset purchases, business expansions, and capital expenditures.

Sinking fund (A) = P × [tex]\frac{(1+r/n)^{tn}-1}{r/n}[/tex]

Where

A – Money accumulated

P – Periodic contribution,

r – Interest rate

t – Number of years

n – Number of payments per year

So, periodic contribution P = A / (((1 + r / n) ^ (t * n) – 1) / (r / n))

Here given that,

A – 270,000

r – 5%

t – 28 years

Answer:

no solution that's my answer

The valid solution to the problem is: The smallest value of all the common fractions that can be formed using the digits 3, 4, 5, and 8 is 34/85.The smallest value of all the common fractions that can be formed using the digits 3, 4, 5, and 8 is 34/85.

Let's solve the problem step by step to determine the smallest value of all the common fractions that can be formed using the digits 3, 4, 5, and 8. We'll express the answer as a reduced fraction.

We have 4 boxes arranged in a square as described:

 A  B

 C  D

The fraction can be represented as AB/CD.

To make the fraction as small as possible, we need to arrange the digits in a specific way. We want to minimize the numerator (AB) and maximize the denominator (CD).

For the numerator (AB), we want the smallest two-digit number. The smallest two-digit number that can be formed using the digits 3, 4, 5, and 8 is 34.

For the denominator (CD), we want the largest two-digit number. The largest two-digit number that can be formed using the digits 3, 4, 5, and 8 is 85.

Therefore, the smallest fraction that can be formed is 34/85.

To ensure that this fraction cannot be further reduced, we need to check if 34 and 85 share any common factors greater than 1. If they do not share any common factors other than 1, then the fraction is in its reduced form.

Checking for common factors:

Factors of 34: 1, 2, 17, 34

Factors of 85: 1, 5, 17, 85

The only common factor is 1, which means the fraction 34/85 is already in its reduced form.

Thus, the valid solution to the problem is:

The smallest value of all the common fractions that can be formed using the digits 3, 4, 5, and 8 is 34/85.
