What is 2 and 1/3+ 3 and 1/3

Mathematics

pychu [463]3 years ago

The question is asking you to add mixed numbers together. The two mixed numbers you want to add up are 2 1/3 and 3 1/3.

This question is fairly simpler than other mixed number or fraction types of problems because the fractions attached to the whole numbers already come having common denominators.

This means you don't have to do anything extra to the fractions to add them; you can just add the numerators (top numbers) together and keep the denominators the same.

Add the fractions (1/3) together first.

1/3 + 1/3 = 2/3

Now add the whole numbers together.

2 + 3 = 5

Combine the whole number and the fraction together to create the mixed number as your answer. Your answer is 5 and 2/3.

Write the standard form of the equation of the parabola with the given focus or directrix and
horsena [70]

Answer:

x = 1/20 y^2

Step-by-step explanation:

This is a rightward opening  (sideways ) parabola

Directrix = x = -5

Distance formula form point x,y  to directrix and focus are equal:  

(x - -5)^2 = (x-5)^2 + y^2

x^2 + 10x + 25 = x^2 - 10x  + 25 + y^2

20x = y^2

x = 1/20 y^2

30. What is the solution to the system of equations?
sukhopar [10]

Answer:

x = 3

y = 0

z = 8

Step-by-step explanation:

a) 3x + 3y - z = 1

b) z = 8

c) -x -3y + 2z = 13

a) 3x + 3y - 8 = 1 (substitution)

a) 3x + 3y = 9

c) - x - 3y + 2(8) = 13 (substitution)

c) -x - 3y + 16 = 13

c) -x - 3y = -3

(3x + 3y = 9) + (-x -3y = -3)

= 2x = 6

x = 3

a) 3(3) + 3y - 8 = 1

9 + 3y - 8 = 1

y = (1 -9 + 8)/3

y = 0
