We will say that x is the salary before the raise, to calculate how much the salary grows, we just have to take the given percent from x, in this case, the payment increased by 4% (0.04 expressed in decimal form) then the increased amount would be x times 0.04.

Salary increase = x*0.04 = 0.04x

Adding 0.04 x to the original salary x (before applying the increase) we get the actual monthly salary, $2,496, then we can formulate the following expression:

Current salary = original salary + salary increase

2,496 = x + 0.04x

From this equation, we can solve for x like this:

1. Factoring x on the right side of the equation:

2,496 = x(1+0.04)

2. making the sum inside the parentheses:

2,496 = x*1.04

3. Dividing both sides by 1.04:

2,496 / 1.04 = x * 1.04 / 1.04

2400 = x

x = 2400

Then, Linda was making $2400 before the pay increase

The standard deviation in statistics is a measurement of how much a group of values can vary or be dispersed. A low standard deviation suggests that values are often close to the set's mean, whereas a large standard deviation suggests that values are dispersed over a wider range. It demonstrates how different things are from the standard.

Given Data

And in the second blank it will be,

If x represents the age of the youngest child, then the equation that models this scenario is x+3(x+4) = 5(x+2)-5 and the ages of the three sisters are 7, 9 and 11 years respectively.

According to the question,

We have the following information:

There sisters have ages that are consecutive odd integers. The sum of the age of the youngest and three times the age of the oldest is five less than five times the middle sister's age.

Age of youngest sister = x years

Middle sister = (x+2) years

Oldest sister = (x+4) years

Now, the equation according to the given situation is:

(a) x+3(x+4) = 5(x+2)-5

(b) Now, we can solve this equation:

x+3x+12 = 5x+10-5

4x+12 = 5x+5

12-5 = 5x-4x

x = 7

Middle sister = 7+2 = 9 years

Oldest sister = 7+4 = 11 years

Hence, the equation is x+3(x+4) = 5(x+2)-5 and their ages from the youngest to the oldest are 7, 9 and 11 years respectively.

Step-by-step explanation:

With the full question now given (see attached image), I would allocate equal resources to Whole Milk and 0-1% fat milk. This exercise is about the Allocation of Resources in a free economy with the help of market trends. See further explanation below.

The allocation of available resources to diverse purposes is referred to as resource allocation in economics. In the framework of a whole economy, resources can be distributed through a variety of mechanisms, including markets and planning.

Note that in the attached graph, the demand for Whole Milk has been falling while the demand for 0-1% fat is dropping. While the reasons for this trend is beyond the scope of this exercise, suffice it to say that it is reasonably expected that the consumption data in 2001 will most likely be equal to each other.

1980 to 1985 the movement in 0-1% fat milk was negligible but it shot up the next 5 year period.

It is logical to expect that this pattern will reoccur since the demeand has been stable for the last 10 years (hence a reoccurring pattern).

On the other hand, every 5 years, the demand (consumption) for Whole Milk has consistently dropped. Hence the reason for the decision.

Mark knows the account number includes the numbers 2,3,5,7,8, and 9. There are obviously 6 numbers in total in this set and 6 he must choose in order to have a 6 digit account number, which the problem also directly states he has.

That means P(n,r) = P(6,6)

The number such that when 3/4of it is added to 3 whole number 1/2 the sum is the same as when 2/3 of it is subtracted from the 6 whole number 1/2 is 36/17

A fraction, which derives from the Latin word fractus, which means "broken," is a portion of a whole or, more broadly, any number of equal pieces. A fraction, such as the one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English. A common, vulgar, or simple fraction is one that has a non-zero denominator that is displayed below (or after) the line on which the numerator is shown. Compound fractions, complicated fractions, and the mixed numeral fractions are examples of uncommon fractions that use numerators and denominators.

The numerator and denominator of the positive common fractions are both natural integers. The denominator tells how many of those equal parts make up single unit or fraction, whereas the numerator represents the number of equal parts. Since a whole can never be made up of zero parts, denominator cannot be zero.

By solving a system of equations we will see that 8 cups were sold on store A.

Let's define:

c= cups sold on store A.

p = plates sold on store A.

pᵇ = plates sold on store B

cᵇ = cups sold on store B.

For "Store B sold twice as many cups and half as many plates"

We can write:

pᵇ = 0.5*p

cᵇ = 2*c

We can write the system of equations:

c + p = 36

0.5*p + 2*c = 39

We want to solve this for c, so we isolate p on the first equation and replace that in the second one.

p = 36 - c

0.5*(36 - c) + 2c = 39

18 + 1.5*c = 30

1.5*c = 30 - 18

The given functions are

r(x) = - 2x - 2

s(x) = x^2 + 2

To find s(r(4)), the first step is to substitute x = - 2x - 2 into s(x) = x^2 + 2. Thus, we have

s(r(x)) = (- 2x - 2)^2 + 2

s(r(x) = (- 2x - 2)(- 2x - 2) + 2

s(r(x) = 4x^2 + 4x + 4x + 4 + 2

s(r(x)) = 4x^2 + 8x + 6

Finally, we would substitute x = 4 into s(r(x) = 4x^2 + 8x + 2. Thus, we have

s(r(4)) = 4(4)^2 + 8(4) + 6

s(r(4)) = 64 + 32 + 6

a. The answer to the subject of the formula, "d," is d = P/64.

b. A submerged object will be 10. 5 feet deep at a pressure of 672 pounds per square foot.

What is a function?

A function can be defined as an expression, law or rule that shows the relationship between two variables.

These variables are namely;

given the role as;

P = 64d

Where;

P stands for pounds per square foot of pressure.

d represents the object's depth in feet.

Let's now make the variable "d" the focus of the formula.

The coefficient of the variable "d," which is 64, is used to divide both sides of the equation. So that the variable can stand on its own, this is done.

We possess

P/64 = 64d/64

d = P/ 64

P equals 672 pounds per square foot if there is pressure.

When the variable's value is substituted into the formula, we get;

d = P/64

Then,

d = 672/64

Discover the quotient.

d = 10. 5 ft.

The value is 10.5 feet.

Therefore,

a. The answer to the subject of the formula, "d," is d = P/64.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

2x + 3 is an example of a variable mathematical expression. Every variable must have a coefficient, which is a number multiplied by the variable. The coefficient of x in the formula 2x + 3 is the number 2, and it signifies 2 times x plus 3.

The expression that shows the distance on the number line between 2 and −7 is |2−(−7)|. If we solve the given expression to calculate the distance then it can be solved as,

||2−(−7)||

= ||2 + 7||

The rate of change of y with respect to x for this function is equal to: C. 2.

In Mathematics and Geometry, the rate of change (slope) of any straight line can be determined by using this mathematical equation;

Rate of change (slope) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Rate of change (slope) = rise/run

Rate of change (slope) = (y₂ - y₁)/(x₂ - x₁)

By substituting the given data points into the formula for the rate of change (slope) of a line, we have the following;

Rate of change (slope) = (y₂ - y₁)/(x₂ - x₁)

Rate of change (slope) = (5 - 1)/(2 - 0)

Rate of change (slope) = 4/2

Rate of change (slope) = 2.
