Using the concept of solving equation, (a) after four months, the total cost would be the same and (b) total cost for each club A and B are: 105.

Equations simultaneously, or a system of equations Multiple equations in algebra must be solved simultaneously. There must be an equal number of equations and unknowns for a system to have a singular solution. When two or more equations use the same variables, they are said to be in a system of equations. Graphing, substitution, and elimination are the three techniques used to solve systems of equations.

Let, x be the number of months of membership

y be the total cost

Club A : y = 20x + 25 ......... (i)

Club B : y = 23x + 13 ........... (ii)

Because we know that the prices, y would be equal, we can set the two equations equal to each other.

20x + 25 = 23x + 13

or, 3x = 12

or, x = 4

So, after four months, the total cost would be the same.

Total cost for each club A and B are: 105.

Answer:

m = 5 and n = 6

Step-by-step explanation:

In a parallelogram, opposite sides of the figure are congruent (equal to each other).

This means that 3m - 7 = m + 3 and 2n + 12 = 4n

We can now solve for the variables

3m - 7 = m + 3

==> add 7 to both sides

3m = m + 10

==> subtract 2 from both sides

2m = 10

==> divide both sides by 2

m = 5

2n + 12 = 4n

==> subtract 2n from both sides

12 = 2n

==> divide both sides by 2

6 = n

Answer:

n=6,m=2

Step-by-step explanation:

4n=2n+12

2n =12

n=6

m+3=3m-1

4=2m

m=2

Their ages Mario is four years old, while Martina is five.

If a person is "x" years old now, then "n" years from now, that person will be "x + n" years old. The age of this would be equal to x - n years n years ago.

Mario is four years old, while Martina is five.

Explanation:

2x -y = 6 adding two to the number 4x -2y = 12

3x + 2y = 23

The sum of the two figures

4x - 2y = 12

3x + 2y = 23

7x = 35 by 7 multiply both sides.

Marina is x years old.

2x - y = 6 Put 5 in place of x, then figure out y.

2(5) -y = 6

10 -y = 6 From both sides, deduct 10

-y = -4 Divide the two sides by -1.

a.  An inequality to represent how long the family should drive on the first day :

n ≥ 11.

b. the family should drive 11 hours.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given:

To get to the beach for vacation,

Cheng's family must drive at least 660 miles on the first day.

They are traveling at a constant speed of 60 miles per hour.

The total time  = 660 / 60 = 11 hours.

That means, the family should drive 11 hours.

An inequality to represent how long the family should drive on the first day :

The number that replaces the question mark is 5.

Number is a mathematical object used to count, measure, and label. It is an abstract concept that can be represented by a symbol, such as a numeral or word. Numbers are used in various ways, including counting, measuring, and labeling. They can also be used to represent relationships between objects and ideas, and to measure the size, volume, and distance of objects.

This is because the pattern of the sequence is to add the two numbers that are next to each other together to get the next number. In the sequence, the two numbers that are next to the question mark are 6 and 7. When 6 and 7 are added together, the result is 13. Since 13 is greater than 12, the next number in the sequence must be 5.

The perimeter of the triangle is  40.42 cm

The height of the triangle is 14 cm

A right triangle's three sides are related in Euclidean geometry by the Pythagorean theorem, also known as Pythagoras' theorem. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

The length of the base is 9.5 cm

The total area of the triangle is 66.5 cm²

We know,

Area = (1/2)*base * height

⇒ 66.5 = (1/2)*9.5* h

⇒h = 14 cm

The height is 14 cm

By using Pythagoras theorem  

hypotenuse = √{(base)² + (height)²} = √{(9.5)² + (14)²}  = 16.92 cm

The hypotenuse is 16.92 cm

The perimeter of the triangle is height + base + hypotenuse = 14 + 9.5 + 16.92 = 40.42 cm

Step-by-step explanation:

This is because the point (1,4) is on the line.

a) The amount of the monthly mortgage payment is 843.86

b) The total amount of interest Ato Liku that will pay over the life of the mortgage is 104,000

c) The amount of the mortgage Ato Liku will have paid after 10 years is 101,263.20

a) To determine the amount of the monthly mortgage payment, we need to use the formula for the monthly mortgage payment (also known as the loan payment formula):

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1]

where M is the monthly mortgage payment, P is the principal (the remaining balance after the down payment), i is the monthly interest rate (12%/12 = 1%), n is the number of payments (30 years x 12 months/year = 360 payments), and ^ denotes exponentiation.

P = 250,000 x (1-.20) = 200,000

n = 30 x 12 = 360

i = 0.12/12 = 0.01

M = 200,000 [ 0.01(1 + 0.01)^360 ] / [ (1 + 0.01)^360 - 1]

M = 843.86

b) To determine the total amount of interest Ato Liku will pay over the life of the mortgage, we can subtract the original loan amount (200,000) from the total amount of the payments over the life of the loan:

total interest = total payments - original loan amount

total payments = M x n = 843.86 x 360 = 304,000

total interest = 304,000 - 200,000 = 104,000

c) To determine the amount of the mortgage Ato Liku will have paid after 10 years, we need to multiply the monthly mortgage payment by the number of payments made after 10 years.

10 years x 12 months/year = 120 months

Mortgage paid after 10 years = 843.86 x 120 = 101,263.20

Answer: x is equal to 0.88

Step-by-step explanation:

To solve for x, we can start by simplifying both sides of the equation:

89(54x - 36) + 2 = -34(-40 + 16x) + 90x

First we can simplify the left side of the equation:

89(54x - 36) + 2 = 4846x - 3204 + 2 = 4846x - 3202

Now we can simplify the right side of the equation:

-34(-40 + 16x) + 90x = -34(16x - 40) + 90x = -544x + 1360 + 90x = -454x + 1360

Now we can set the left side of the equation equal to the right side and solve for x:

4846x - 3202 = -454x + 1360

Now we can add 454x to both sides and subtract 1360 from both sides

5,300x = 4660

x = 4660/5300

x = 0.88

Therefore, x is equal to 0.88

Answer:

0.86

Step-by-step explanation:

89(54x-36)+2=-34(-40+16x)+90x

4806x-3204+2=1360-544x+90x

4806x+500x-90x=3204-2+1360

5260x=4562

x= 4562/5260

The function that represents the point (x, y) being reflected across the y-axis is F(x, y) = F(-x, y)

A point (x, y) can be reflected across the y-axis by multiplying the x-coordinate by -1.

This is because the y-axis is a vertical line running through the center of a coordinate plane, and reflecting a point across this line means reversing its position along the horizontal (x) axis.

So, to reflect a point (x, y) across the y-axis, the function can be represented as:

f(x, y) = (-x, y)

This function takes in the coordinates (x, y) of a point and returns the new coordinates (-x, y) after reflecting it across the y-axis.

x−y=−2

4x−y=4

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

x−y=−2,4x−y=4

Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.

x−y=−2

Add y to both sides of the equation.

x=y−2

Substitute y−2 for x in the other equation, 4x−y=4.

4(y−2)−y=4

Multiply 4 times y−2.

4y−8−y=4

Add 4y to −y.

3y−8=4

Add 8 to both sides of the equation.

3y=12

Divide both sides by 3.

y=4

Substitute 4 for y in x=y−2. Because the resulting equation contains only one variable, you can solve for x directly.

x=4−2

Add −2 to 4.
