Step-by-step explanation:

Let a be the number of adults, and let c be the number of children. We set up and solve this system of equations:

a + c = 267---------> 7a + 7c = 1869

12a + 7c = 2379------->12a + 7c = 2379

-----------------------

5a = 510

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

1.5*c = 12

c = 12/1.5 = 8

Answer:

The sand is 2/5 and the cement is 5/7

Step-by-step explanation:

You need to get the total parts of both by adding the numerator and the denominator, and then divide the amount of parts by the total amount of parts.

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

s(r(4)) = 102

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.

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

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.

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.

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

Answer:

Step-by-step explanation:

sorry if it doesnt help

The correct expression to show the distance between 2 and -7 is :

∣∣2−(−7)∣∣

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||

= ||9||

= 9

Hence, the expression that shows the distance on the number line between 2 and −7 is 9 units.

Answer:

720

Step-by-step explanation:

Formula: P (n,r) = n! ÷ (n - r)!

n = Total number of objects in a set

r = The number of items you choose

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)

!/Factorial = Product of all positive numbers less than or equal to the given positive number

Therefore, 6! = 1 x 2 x 3 x 4 x 5 x 6

P (n,r) = P(6,6) = 6! ÷ (6-6)! = 720
