Answer:

5/8

Step-by-step explanation:

B is the correct answer.....

The solution to the system of equation is x = 9 /2 and y = - 3 / 2

y = 5 / 3 x + 3

y = 1 / 3 x - 3

Therefore, let subtract equation(i) from equation (ii) to eliminate y

5 / 3 x - 1 / 3 x = 3 + 3

5x - x / 3 = 6

4x / 3 = 6

cross multiply

18 = 4x

x = 18 / 4

x = 9 / 2

Therefore,

y = 1 / 3(9 / 2) - 3

y = 9 / 6 - 3

y = 9 - 18 / 6

y = - 9 / 6

y = - 3 / 2

Answer:

x = 28

Step-by-step explanation:

Let the total number of students = x

x/7 + 3x/7 + 2x/7 + 4 = x If that is all there is.  If it isn't the problem can't be done. Combine like terms.

x(1 + 3 + 2)/7 + 4 = x

x (6/7) + 4 = x                       Subtract 6x/7 from both sides

4 = x - 6x/7

4 = 7x/7 - 6x/7                     Combine

4 = 1/7x                                Multiply both sides by 7

4*7 = 7x / 7

x = 28

Answer:

x = 13.5

y = 7

(13.5,7)

what the solution means is that (13.5,7) would be the point at which the two lines, x+y=20.5 and x-y=6.5, would intersect

Step-by-step explanation:

x + y = 20.5

x - y = 6.5

if we add the two equations we get:

2x = 27

x = 13.5

y = 20.5 - 13.5

y = 7

solution as an ordered pair:

(13.5,7)

What the solution means is that (13.5,7) would be the point at which the two lines, x+y=20.5 and x-y=6.5, would intersect

in total mario has 16 short stories

The total number of stories that Mario has will be 28.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

Mario has 3 books of short stories. Each book has 5 stories. He has 13 other short stories.

The total number of stories is calculated as,

Total = 5 x 3 + 13

Total = 15 + 13

Total = 28

Answer:

ΔLNM is proved as isosceles triangle. Below for explanation.

Step-by-step explanation:

We know that:

Since AMBX is a square, AL must equal to BN because they are the extra lengths of the square. The lengths of the square are AM, MB, BX, XA.

This can tell us that the two sides of the triangle are equal. We also know that if 2 sides of a triangle are equal, it is classified as an isosceles triangle. Hence, ΔLNM is proved as an isosceles triangle.
