Maria, Zach y Jill comparten una pizza. Maria come la mitad de la pizza, Zach come 4/6 y Jill come 3/12 de la pizza. ¿Quién come más?

Answers

Answer 1

Answer:

Answer:

Jill

Step-by-step explanation:

Spanish:

Necesitamos asegurarnos de que ambas fracciones tengan el mismo denominador para descubrir quién se comió la porción más grande.

Jill comió $(4)/(6)$ de la pizza, Zach comió $(3)/(12)$ de la pizza, y María comió $(1)/(2)$ de la pizza
Podemos manipular estas fracciones para que ambas tengan el mismo denominador de 12.
Para hacerlo, podemos multiplicar la porción de Jill por $(2)/(2)$ lo que haría su porción $(8)/(12)$ y la porción de María por $(6)/(6)$ la cual haría su porción $(6)/(12)$

Ahora podemos comparar las tres fracciones y ver cuál tiene el numerador más grande

Comparando $(8)/(12)$ , $(3)/(12)$ , y $(6)/(12)$ , podemos ver que 8 > 6 > 3, lo que significa que Jill comió más pizza

English:

We need to make sure both fractions have the same denominator to figure out who ate the bigger portion.

Jill ate $(4)/(6)$ of this pizza Zach ate $(3)/(12)$ of the pizza, and Maria ate $(1)/(2)$ of the pizza

We can manipulate these fractions so they all have the same denominator of 12.

To do so, we can multiply Jill's portion by $(2)/(2)$ which would make her portion $(8)/(12)$ and Maria's portion by $(6)/(6)$ which would make her portion $(6)/(12)$

Now we can compare the three fractions and see which one has the larger numerator

Comparing $(8)/(12)$ , $(3)/(12)$ , and $(6)/(12)$ we can see that 8 > 6 > 3 which means Jill ate more pizza

One number is 3 more than 3 times another. The sum of the numbers is 19. Find the two numbers.The two numbers are
and

Answers

Answer:

number x

y = 3x +3

sum = x + y

19 = x + 3x + 3

19 = 4x + 3

19- 3 = 4x

16 = 4x

16/4 = x

x = 4

im ading and subtracting rational expression.my question is 5 is the numerator 2x -1 is the denominator + 6x +7 and 1 -4x squared

Answers

It's my method of solving this type of account, i get the denominators and multiply them by the fractions, then you cut the denominators, any questions just ask, i don't think that it was clarifying:

(2x-1) . (1-4x^2) . (5/2x-1) + (2x-1) . (1-4x^2) . (6x/1-4x^2) =
-> (1-4x^2) . 5 + (2x-1) . 6x =
-> 5 - 20x^2 + 12x^2 - 6x =
-> -8x^2 - 6x + 5 = 0

Delta = (-6)^2 - 4.(-8).5
Delta = 36 + 160 = 196

x' = - (-6) + sqroot(196) / 2.(-8)
x' = 6 + 16 / -16
x' = 22/-16 (simplifying by 2) = -11/8

x'' = 6 - 16 / -16 = -10/-16 (simplifying by 2)
x'' = 5/8

Find two consecutive positive integers such that the square of the first decreased by 67 is equal to three times the second

Answers

Answer:

The numbers are 10 and 11.

Step-by-step explanation:

Let $x$ and $x+1$ be consecutive positive integers.

When the problem says that the square of the first decreased by 67 this means $x^2-67$ and this is equal to three times the second $3(x+1)$ .

So $x^2-67=3(x+1)$ will be our equation.

Next, we solve the equation:

$x^2-67=3x+3\n\nx^2-70=3x\n\nx^2-3x-70=0$

Solve by factoring

$x^2-3x-70= \left(x^2+7x\right)+\left(-10x-70\right)\n\nx^2-3x-70=x\left(x+7\right)-10\left(x+7\right)\n\nx^2-3x-70=\left(x+7\right)\left(x-10\right)=0$

Using the Zero Factor Principle: If ab = 0, then either a = 0 or b = 0, or both a and b are 0.

$x+7=0\nx=-7$

And

$x-10=0\nx=10$

Because the numbers need to be positive integers, we only take x = 10 as a valid solution.

The numbers are 10 and 11.
