The answer of 2/7 + 3/5 is a fraction. The answer is 31/ 35.
To add two fractions, the denominators must be the same, in this case, the denominators are different, so we need to find a common denominator to add these two fractions.
A common denominator for 2/7 and 3/5 is 35.
So we can convert both fractions to have 35 as the denominator,
2/7 becomes (2×5)/(7×5) = 10/35
3/5 becomes (3×7)/(5×7) = 21/35
then we can add the numerators:
10/35 + 21/35 = 31/35
so the final answer is 31/35
This is also the simplest form of this fraction which would be 31/35.

6x + 11= 21 tape diagram
Answer:
x = 5/3
Step-by-step explanation:
6x + 11 = 21
6x = 10
x = 10/6
x = 5/3
Let's check
6(5/3) + 11 = 21
30/3 + 11 = 21
10 + 11 = 21
21 = 21
So, x = 5/3 is correct!

4 Siobhan and Ralph shared £700 in the
ratio 2:3.
Siobhan gave a quarter of her share to Karen.
Ralph gave a fifth of his share to Karen.
What fraction of the £700 did Karen receive?
Therefore ,the solution to the given problem of proportion comes out to be karen got £70.
What is a proportion?The rule of three is used to link the measures because a proportion is a fraction of a total amount. It is possible to construct equation or relations between variables that are either direct (when both rise or decrease) or inverse proportional (when one increases and the other declines, or vice versa) in order to determine the necessary measures in the situation.
Here,
Given :
Siobhan and Ralph shared £700 in the
ratio 2:3.
Thus,
280 / 420 = 2/3
Thus,
Siobhan and Ralph has £280 and £420 respectively.
and Siobhan gave a share of quarter to karen :
So,
280/4 =70

What is the height formula of isosceles triangle?
The formula for finding the height of an isosceles triangle is h = (2*A)/b, where h is the height, A is the area of the triangle, and b is the base of the triangle.
The formula for finding the height of an isosceles triangle is h = (2*A)/b, where h is the height, A is the area of the triangle, and b is the base of the triangle. To use this formula, the area of the triangle must first be calculated. To do this, multiply the base of the triangle by its altitude, or the perpendicular distance from the base to the vertex opposite it. Once the area is known, the height of the triangle can be calculated by multiplying the area by two and dividing it by the base. This will give the height of the triangle. For example, if a triangle has a base of 5 and an area of 10, then the height of the triangle is (2*10)/5, or 4.

Step-by-step explanation:
Mr cam bought 6 pizza for the che club if each of the 10 member ate 1/4 of the pizza how many pizza were eaten
The total number of pizzas consumed by the 10 members of the club is 2.5 and 3.5 pizzas remain, as Mr. Cam bought 6 pizzas and each of the 10 members ate 1/4 of a pizza.
Mr. Cam bought 6 pizzas for the club and each of the 10 members ate 1/4 of the pizza. To find out how many pizzas were eaten, we can use the formula:
Number of members x Pizza per member = Total Pizzas Consumed
In this case, we can substitute the given values in the formula:
10 members x 1/4 pizza/member = 10/4 = 2.5 pizzas
This means 2.5 pizzas were consumed by the members. Since Mr. Cam bought 6 pizzas and 2.5 pizzas were eaten, the total number of pizzas remaining is 6 - 2.5 = 3.5 pizzas.
This equation works because it uses the concept of the unitary method, where we find the total number of pizzas consumed by multiplying the number of members by the number of pizzas each member ate. This way we can find the total amount of pizza consumed.

What is the equation?A formula for connecting two statements using the equal sign (=) to denote equivalence is known as a mathematical equation. A mathematical equation in algebra is a statement that proves the equality of two mathematical expressions. For instance, the formula 3x + 5 = 14 places an equal sign between the variables 3x + 5 and 14. The mathematical relationship between the two sentences on either side of a letter is established. Most of the time, the symbol serves as both the one and only variable. for instance, 2x – 4 = 2.
Here,
For C no of cars
=> Profit = total earning in a month - Expense in a month
=> (25-6)C - (23500-6000)
=> P = 19C-17500
If 3000 cars serviced then,
=> Profit = 19(3000)-17500
=> Profit = 39500
If no of cars received in particular month is 900 then profit or loss
=>Profit = 19(900)-17500

If the ratio between students to female adults is 7:6 while female adults to male adults is 4:1. What is the ratio of students to male adults?
Answer: 14:3
Step-by-step explanation:
Given
Ratio between students(s) to female(f) adults is 7:6
while ratio between female(f) to male(m) is 4:1
So, we can write
[tex]\Rightarrow \dfrac{s}{f}=\dfrac{7}{6}\quad \ldots(i)[/tex]
Also, we can write
[tex]\Rightarrow \dfrac{f}{m}=\dfrac{4}{1}\quad \ldots(ii)[/tex]
Multiply both equations
[tex]\Rightarrow \dfrac{s}{f}\times \dfrac{f}{m}=\dfrac{7}{6}\times \dfrac{4}{1}\\\\ \Rightarrow \dfrac{s}{m}=\dfrac{14}{3}[/tex]
So, the ratio of the students to male adults is 14:3 .

The two sets A and B triangle must have identical items, but this does not require that they be put in the same order for the sets to be equal.
Describe the triangle.A triangle is a 2D shape with three vertices, three straight edges, and three straight edges. A key feature of these shapes is that each type of triangle has three inner angles that add up to 180° in these designs. during their math lectures about these angles and how to use this quality to spot missing values.
Here,
Triangle 1 in this instance has two angles, one of 34 degrees and the other of 48 degrees.
The third angle is therefore 180-34- 48=98.
The angles in Triangle 2 are 34 and a, where an is 48, respectively.
In other words, the third angle is 180−34−a=146−a≠146−48=98.
Jennifer claims that given the information at hand, triangles 1 and 2 cannot be compared.
If 34,98,48=34,a,146a., they are equivalent.
How many degrees will Jennifer's claim be ruled untrue? To compare the triangles, use the formula a.
It is crucial to understand that while components in two sets A and B must match, the sets are not always equal if they are not listed in the same order.

Answer:
Answers below!
Step-by-step explanation:
-9 x -5 = 45
45 x - 6 = -270
-270 x -3 = 810
The answer is positive because a negative multiplied by a negative equals a positive number.
-9 x -5 = 45
45 x 6 = 270
270 x -3 = -810

Give 2 numercial expressions that can be compared without calculating the values. Explain.
The numercial expressions that can be compared without calculating the values include:
3x^2 + 4x - 5 > 2x^2 + x - 3
2/x < 4/x
How to illustrate the expressionIn 3x^2 + 4x - 5 > 2x^2 + x - 3. This expression can be compared without calculating the values because it is a comparison of polynomials of the same degree (both are quadratics). The degree of a polynomial (in this case 2) is the highest power of the variable in the expression. Since the degree is the same, we can directly compare the coefficients of the highest degree term (x^2) and the second highest degree term (x) without calculating the values. In this case, 3x^2 > 2x^2 and 4x > x, therefore the polynomial on the left side is greater than the polynomial on the right side.
For 2/x < 4/x, this expression can be compared without calculating the values because it is a comparison of two different fractions, both of which have a common denominator of x^2. Since the denominators are the same, we can directly compare the numerators. In this case, 2 < 4, therefore the fraction on the left side is less than the fraction on the right side.
