The sum of the numbers 13 + 13 + 13 is 39.
What is Addition?Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum.
Given expression is,
13 + 13 + 13
Here 13 is added to itself three times.
When 13 added to 13, we get 13 + 13 = 26
Again if we add the number 13 to 26, we get 13 + 26 = 39
13 + 13 + 13
= 26 + 13
= 39
This can also be written in the form of multiplication as 3 × 13, which is also equal to 39.
Hence the number 13 added to itself three times gives 39.

In London. I pint of milk costs 58p.
In Paris, 1 litre of milk costs 1.05 euros.
1 litre = 1.76 pints
£1 = 1.17 euros
In which city is the milk better value for money, London or Paris?
You must show your working.
Comparing the equivalent cost of Milk in Euro in the two countries, then we can conclude that Milk is a better value for money in Paris.
In other to make accurate comparison of the cost ; we need to using the same unit or milk and same currency value :
Cost of 1 pint of Milk in London :
1 pint = 0.58 pounds
The equivalent value of 1 pint of Milk in terms of Euro in London will be :
1 pound = 1.17 euro
0.58 pound = x
Cross multiply :
x = 1.17 × 0.58
x = 0.6786 euro
x = 0.68 euro
Hence, 1 pint of Milk cost 0.68 euro in London
Cost of 1 pint of Milk in Paris :
1 Litre = 1.76 pint
Hence,
1.76 pint = 1.05 euro
1 pint = c
1.76c = 1.05
c = 1.05 / 1.76
c = 0.597 euro
Hence, cost of 1 pint of Milk cost 0.60 euro in Paris
Therefore, since the cost of Milk in Paris cost less in Paris than in London, then Milk is a better value for money in Paris.

Answer:
The value of the algebraic expression when n is given as 6 will be 38.
An algebraic expression is when we use numbers and words in solving a particular mathematical question.
Based on the information given in the question, the expression will be:
= 1 + 7n - 5
Note that the value of n = 6
Therefore, 1 + 7n - 5 will be:
= 1 + 7n - 5
= 1 + 7(6) - 5
= 1 + 42 - 5
= 38
Step-by-step explanation:Therefore, the value of the algebraic expression when n is given as 6 is 38.

Explain.
Answer: Horizontal Line
Step-by-step explanation:
Joy is correct. This is a horizontal line. It has the same y coordinates so it will be a horizontal line.
Joy is saying correct by saying it is a horizontal line.
What is coordinates?Coordinates are a set of values which helps to show the exact position of a point in the coordinate plane.
Given:
coordinates (-9, 4) and (6,4)
If we plot these point on the graph it will have the y- coordinates same for both coordinates.
Also, if the graph have same y- coordinates then the line joining these points are horizontal in nature.

The number T of teams that have participated in a robot-building competition for high-school students over a recent period of time x(in years) can be modeled by T(x) = 17.155x^2 + 193.68x + 235.81, 0 ≤ x ≤ 6.
After how many years is the number of teams greater than 1000? Justify your answer.
Solving the quadratic equation, it is found that the number of teams is greater than 1000 after 3.1 years.
The number of teams after x years is given by:
[tex]T(x) = 17.155x^2 + 193.68x + 235.81[/tex]
Initially, there are T(0) = 236 teams. If will 1000 be when T(x) = 1000, thus:
[tex]17.155x^2 + 193.68x + 235.81 = 1000[/tex]
[tex]17.155x^2 + 193.68x - 764.19 = 0[/tex]
Which has coefficients [tex]a = 17.155, b = 193.68, c = -764.19[/tex], then:
[tex]\Delta = (193.68)^2 - 4(17.155)(-764.19) = 89950.66[/tex]
[tex]x_{1} = \frac{-193.68 + \sqrt{89950.66}}{2(17.155)} = 3.1[/tex]
[tex]x_{2} = \frac{-193.68 - \sqrt{89950.66}}{2(17.155)} = -14.3[/tex]
We want the positive root, so the number of teams is greater than 1000 after 3.1 years.

While making a sketch for art class, Justin drew the shape shown and then wanted to make sure the triangles were perfectly congruent. After labeling the figure, he used a ruler and found that DF and GE bisect each other at point H.
Which of the following could Justin use to prove ∆DEH ≅ ∆FGH?
A. SAS
B. SSA
C. definition of perpendicular bisector
D. alternate interior angles are congruent
The two triangles have a pair of corresponding sides as well as the
included angles between them that are equal.
Justin could prove that ΔDEH ≅ ΔFGH by A. SAS
Reason:
The known information are;
DF bisects GE, therefore; GH = EH
GE bisects DF, therefore; DH = FH
∠DHE = ∠FHG by vertical opposite angle theorem
Therefore;
DH and EH in triangle ΔDEH = FH and GH in triangle ΔFGH
∠DHE in triangle ΔDEH = ∠FHG in triangle ΔFGH
Therefore, two sides and an included angle triangle in ΔDEH are equal to (congruent) to the corresponding two sides and an included angle in ΔFGH.
Therefore;
ΔDEH ≅ ΔFGH by SAS, Side-Angle-Side congruency theorem
