By using simultaneous linear equation, it can be calculated that-

Number of children are 118 and number of adults are 363

What is simultaneous linear equation?

At first it is important to know about linear equation

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A one degree equation is known as linear equation.

Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.

Here, a simultaneous linear equation needs to be solved

Let the number of children be x and number of adults be y

481 people used the public swimming pool.

x + y = 481 ..... (1)

The daily prices are $1.75 for children and $2.00 for adults.
Total price = $(1.75x + 2y)

By the problem,

1.75x + 2y = 932.50

7x  + 8y = 3730 .... (2)

Multiplying (1) by 7

7x + 7y = 3367.... (3)

Subtracting (3) from (2)

y = 363

Putting the value of y in (1)

x  + 363  = 481

x = 481 - 363

x = 118

Number of children are 118 and number of adults are 363

The solution of the given system of equation is (6, 12). So the option c is correct.

In the given question, Carissa works as a babysitter during her summer vacation.

She gets paid one rate for daytime hours and a higher rate for nighttime hours.

One week, she worked 12 daytime hours and 4 nighttime hours and earned $120.

The next week, she earned $60 for a total of 4 daytime hours and 3 nighttime hours.

Let x represent the hourly daytime rate and y represent her hourly nighttime rate.

The system of equations is

12 x + 4 y = 120……………(1)

4 x + 3 y = 60……………(2)

We have to find the solution to the system of equations.

To find the solution for the system of equation we solve the given equation using elimination method.

Multiply equation by 3 on both sides, we get;

12x + 9y = 180

Subtract equation 3 and 1

12x+9y-(12x+4y)=180-120

12x+9y-12x-4y=60

5y=60

Divide by 5 on both side, we get;

y=12

Now putting the value of y in equation 2

4x+3×12=60

4x+36=60

Subtract 36 on both side, we get

4x=24

Divide by 4 on both side, we get

x=6

Hence, the solution of the given system of equation is (6, 12). So the option c is correct.

The correct option is c. It is a solution to f(x) = g(x) because it is the x-coordinate where the two graphs intersect.

x = −1 is also a solution to f(x) = g(x) because it is asking for the values of x that make f(x) equal to g(x). In this case, x = −1 is a value that makes both f(x) and g(x) equal to −1, so it is a solution to the equation f(x) = g(x).

The graph of f(x) = g(x) is simply the set of all points that are on both the graph of f(x) and the graph of g(x)

These points are the points where the two graphs intersect. In this case, the graph of f(x) = g(x) is a single point at x = −1, which is the x-coordinate where the two graphs intersect

D. y + 3= –2/3(x – 3)

E. y – 1 = –2/3(x+3)

An equation that represents a line whose slope is given as m, and it intercepts the y-axis at b, is expressed in slope-intercept form as y = mx + b.

To find the equation of the given line above, pick two points on the line, (0, -1) and (-3, 1) and find the slope (m):

Slope of the line (m) = change in y / change in x = (1 - (-1)) / (-3 - 0)

Slope of the line (m) = 2 / -3

Slope of the line (m) = -2/3.

The line intercepts the y-axis at -1. This means the y-intercept of the line is b = -1.

To write the equation of the line, substitute m = -2/3 and b = -1 into y = mx + b:

y = -2/3x - 1

It can be rewritten as 2x + 3y = –3 in standard form, or as y + 3= –2/3(x – 3) or y – 1 = –2/3(x+3) in point-slope form.

3x = 1500 multiply both sides by 100

x = 500

500x0.12 = 60

The 12 percentage of the number is A = 60

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let's call the number we're looking for N

We can set up an equation based on the information given:

0.03N = 15

To solve for N, we can divide both sides by 0.03:

N = 15 / 0.03

N = 500

So the number we're looking for is 500

Now , the percentage value is = 12 %

Three vertices make up a triangle, a three-sided polygon. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

Given that,

one leg of a right triangle is 6 inches longer than the other leg.

hypotenuse is 30 inches.

Let assume, the other leg be x

It is given that, one leg of a right triangle is 6 inches longer than the other leg. So, One leg = x + 6

Since it is a right angled triangle,

h² = p² + b²

Where, h = hypotenuse

p = perpendicular

B = Base

So, (30)² = (x+6)² + x²

or, x = -24, 18

As, the length of side cannot be negative so x becomes 18.

Thus, x + 6 = 18 + 6 = 24 inches

Hypotenuse = 30 inches

If the ratio of the measure of the three sides of the triangle is 9:7:5 and the perimeter is 191.1 inches, then the three sides of the triangle are 81.9 inches, 63.7 inches and 45.5 inches

The ratio of the measure of the three sides of a triangle = 9 : 7 : 5

Then three sides of the triangles = 9x, 7x and 5x

Where x is the constant

The  perimeter of the triangle = 191.1

The perimeter of the triangle is the sum of the three sides of the triangle

Then the equation will be

9x + 7x + 5x = 191.1
