Using ratios we know that the total number of sweet Debs and Jamie has is 50.

A ratio in mathematics demonstrates how many times one number is present in another.

For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six.

Two quantities are compared to form a ratio.

An equality of two ratios is a proportion.

How to format a ratio Analyze the ratio to see whether it is part to part or part to whole.

Calculate the whole and the pieces as necessary.

So, we have a ratio of 3:7.

Debs has 20 fewer sweets than Jamie.

Let, Jamie have x sweets and Debs has x - 20.

Now, we get the equation:

3/x - 20 = 7/x

Now, solve as follows:

3/x - 20 = 7/x

3x = 7(x - 20)

3x - 7x - 140

7x - 3x = 140

4x = 140

x = 140/4

x = 35

x - 20 = 35 - 20 = 15

Total: 35 + 15 = 50

Therefore, using ratios we know that the total number of sweet Debs and Jamie has is 50.

. To find the distance between two points, use the distance formula.

It will be the square root of (x2-x1)squared + (y2-y1)squared.

Use (3,-4) as x1, y1. Use (5,1) as x2, y2.

We get the square root of (5-3)squared + (1- -4)squared.

That gives us the square root of 2 squared + 5 squared.

The missing value of x = 6

What is value ?

Value in mathematics can refer to a number of closely related ideas. A mathematical value can generally be any specific mathematical object. This is most frequently a number in elementary mathematics, such as a real number like or an integer like 42.

Depending on where it is in the number, each digit has a different value, which is referred to as value. We figure it out by multiplying the digit's place value by its face value. Place value plus face value equals value.

Values are the benchmarks or ideals by which we judge the acts, traits, possessions, or circumstances of others. Values that are embraced by many include those of beauty, honesty, justice, peace, and charity.

The four integers say a,b,c and d. If a and b are congruent to moulo m and c ,d are congruent to modulo m then ac and bd are must be congruent to modulo m .

Two integers a and b are "congruent modulo n" if their difference is a multiple of n or in other words we say n/(b-a) . For example, 17 and 5 are congruent modulo 3 because 17 - 5 = 12 = 4×3

We have, a ≡ b mod m => m/(a - b)

and c ≡ d mod m => m/(c-d)

Now, a + c - b - d = (a-b) + (c-d)

because, m/( a - b) and m/(c-d)

=> m/( a-b+ c-d )

=> m/(a+c)-(b+d)

=> a+c ≡ b+d mod m

We have to prove that ac ≡ bd mod m.

ac - bd = c(a-b) + b(c- d)

Now, as we see, m/(a-b) => m/c(a-b)

and m/(c-d) => m/b(c-d)

=> m/(c(a-b) + b(c-d))

=> m/(ac - bc + bc - bd)

Answer: y = -1/2x + 4.

The equation of line passes through the points (0, 4) and (8, 0) will be;

⇒ y = -1/2x + 4

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (0, 4) and (8, 0).

Now,

Since, The equation of line passes through the points (0, 4) and (8, 0)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (0 - 4) / (8 - 0)

m = - 4 / 8

m = -1/2

We know that, The slopes of parallel lines are equal.

Thus, The equation of line with slope -1/2 is,

⇒ y - 4 = -1/2 (x - 0)

⇒ y - 4 = -1/2x

⇒ y = -1/2x + 4

Therefore, The equation of line passes through the points (0, 4) and

If the price is reduced to $11.40 the number of DVDs sold will be 1177.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a video store manager observed that the number of DVDs sold seems to vary inversely to the price per DVD. If the store sells 710 DVDs per week when the price per DVD is $18.90.

The number of DVDs sold for $11.40 will be calculated by forming the inverse equation for the number of DVDs.

N = K / P

Here, N is the number and P is the price and K is the inverse constant.

The value of K will be,

K = N x P

K = 18.90 x 710

K = 13419

The number of DVDs for $11.40 will be,

N = K / P

Answer: y=2(x+1)^2 +7

Step-by-step explanation:

The equation for a parabola is y=a(x-h)^2+k

(h,k) would be the vertex but when writing the equation, the sign in front of the h has to be the opposite of the x-value in the vertex (note: the minus sign in front of the h just means opposite of, not always negative) So in this situation since the 1 is negative, it would be positive in the equation

The a represents the distance from the vertex to the focus.

In order to solve this problem you just sub in the opposite of h and the normal value of k and then the a would be two since that is the distance between the focus and the vertex.

This would make your answer 2(x+1)^2 +7

The integer a=0 and b=0 does not have any greatest common divisor.

Suppose n = gcd(0,r)

Then 12|0 and 12|0 also n is the greatest divides both (a=0), (b=0).

But n+1|0, n+1|0 as (n+1)*0 = 0 which is a contradiction to n = gcd(0, r).

The total cost of painting and carpeting the 4 walls and the floor is C = ₹(720x² + 1324.8x).

Given is that a room three times as long as it is broad and its height is 4.6 m. The cost of carpeting its floor at Rs. 240 per square meter be  the cost of painting the 4 walls at Rs. 24 per sq. m.​

Assume that the breadth to be equivalent to [x] meters. Then its length will be [3x] meters.

Area of floor = {3x} x {x} = 3x² sq. m.​

The cost of carpeting the floor = Rs. 240 per sq. m.

For 1 sq. m., the cost is 240 sq. m.

For {3x² sq. m}, the cost will be -

C{f} = 240 x 3x² = 720x²

C{f} = 720x²

The total area of the 4 walls = 4 × (3x) × 4.6 = 55.2x sq. m.

The cost of carpeting the walls = Rs. 24 per sq. m.

For {55.2x sq. m}, the cost will be -

C{w} = 24 x 55.2x = 1324.8x

C{w} = 1324.8x

The total cost of painting and carpeting -

C = C{w} + C{f} = 720x² + 1324.8x

C = ₹(720x² + 1324.8x)

Therefore, the total cost of painting and carpeting the 4 walls and the floor is C = ₹(720x² + 1324.8x).
