To solve an inequality, we need to isolate the value of x, and to do so we will perform a series of calculations in such a way that it remains the inequality unchanged, or at least still true.

To do so, we will perform first a sum of 2x to both sides of it, as follows:

Now, we subtract 3 from both sides:

To finish it, we divide both sides by 2:

In another way, we can express the following:

It means that the solution is option B.

To solve the second part, we need a filled line that comes from the negative infinity and goes until 2, but it must be including the number 2, and for this reason, the correct answer in the second part is:

It is given that the product of 7 and a number, increased by 3, is equal to twice the number, subtracted from 39.

It is required to find the number.

To do this, write the statement as an algebraic statement.

Let the number be x.

The product of 7 and a number is:

The product of 7 and a number increased by 3 is:

Twice the number is:

Twice the number subtracted from 39 is:

Since it is given that these expressions are equal, it follows that:

Solve the resulting equation for x:

The number is 4.

Answer:

A) 384, 216

b) 14575

Step-by-step explanation:

A) to find the missing values you do 3-1 which gives you 2.

here is a trick!

then you take your answer (in this case it is 216) and add it to your second row (168) to get the first row's answer (384). so you are basically going backward.

B) here you do the same thing go backward!

5967+8608 = 14575

then if you want you can double-check by subtracting them.

The equation that represent the situation of the quadrilateral is 40 = 3q + 7

A quadrilateral is a polygon with 4 sides.

Three sides of a quadrilateral are the same length, q.

The length of the fourth side is 7 inches.

The perimeter of the quadrilateral is 40 inches.

The equation to represent the situation is as follows:

perimeter of a figure is the sum of the whole sides.

Hence,

perimeter of the quadrilateral = q + q + q + 7

perimeter of the quadrilateral = 3q + 7

The change that Grant received to the nearest cent after giving the delivery driver with a $100 bill is $ 32.6.

This is a question of percentages.

Given that:-

Price of bouquet of flowers = $ 55

Sales tax % = 6.5 %

Tip % = 15 %

Delivery fee= $10

We have to find the change that Grant received to the nearest cent after giving the delivery driver with a $100 bill.

Sales tax = (6.5/100)*55 = $3.575

$55 + $3.575 = $58.575

Tip = (15/100)*58.575 = $ 8.78625

Total money paid by Grant = 55 + 3.575 + 8.78625 = $ 67.36125 ≈ $ 67.4

Step-by-step explanation:

the loan payment on a fixed term mortgage loan of $100,000 at 8% for 30 years will be $ 340,000.

Principal amount = $ 100,000

Interest rate = 8 %

Time period = 30 years.

Now, the interest is simple interest as it is a fixed rate/ fixed term mortgage.

So, the interest will be:

Simple interest = p r t / 100

SI = 100,000 × 8 × 30 / 100

SI = $ 240,000

Amount will be:

A = $100,000 + $ 240,000

A = $ 340,000

Therefore, we get that, the loan payment on a fixed term mortgage loan of $100,000 at 8% for 30 years will be $ 340,000.

Given data:

Cost = $26,000

Useful life  = 5 years

Salvage value = $3,200

First step is to calculate the  depreciation expenses:

Particular Amount

Cost $26,000

Less: Salvage value ($3,200)

Net cost (a) $22,800

Useful life (b) 5

Depreciation expenses (a/b) $4,560

($22,800 / 5 years)

Second step is to compute the  book value of furniture on 31 Dec of first year:

To determine the book value we would have to deduct the depreciation expenses from the cost.

Particular Amount

Cost of an furniture $26,000

Less: Depreciation ($4,560)

Using the normal distribution, it is found that the indicated z-score is Z = 1.08. A normal distribution with a mean of zero and a standard deviation of one is known as the standard normal distribution.

A normal distribution with a mean of zero and a standard deviation of one is known as the standard normal distribution. The standard normal distribution is centered at zero, and the standard deviation indicates how much a specific measurement deviates from the mean.

While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

The z-score of a measure X in a normal distribution with mean and standard deviation is given by:

z = (x-μ)/σ,

It counts the number of standard deviations the value deviates from the mean.

We look at the z-score table after determining the z-score to determine the p-value, which is the percentile of X.

We want Z in this problem to have a p-value of 0.8599, thus Z = 1.08.

Answer:

(0, 8) and (-4, 0)

Step-by-step explanation:

Equation is -2x + y = 8

Manipulate this equation so that it becomes a slope-intercept form of equation

To do this:

Add 2x on both sides

-2x + 2x + y = 2x + 8

y = 2x + 8

Once we have this, 2 points which definitely lie on the line are its x and y intercepts

This is the equation of a line with slope = 2 and x-intercept = 8

x-intercept is y-value when x = 0
We can check by plugging in 0 for x in y = 2x + 8

=> y = 2(0) + 8 = 8

=> Point(0, 8) is one of the ordered pairs

Similarly we can find the x-intercept by setting y = 0 and solving for x

Setting y = 0 in y = 2x + 8

=> 0 = 2x + 8

Switch sides

2x + 8 = 0

Subtract 8 from both sides

2x + 8 - 8 = 0 - 8

2x = -8

Divide both sides by 2

=> 2x/2 = -8/2

x = -4

So (-4, 0) is another point on the line

Two ordered pairs are therefore

(0, 8) and (-4, 0)

The attached graph shows you that it is indeed so
