Answer:

\huge\boxed{Answer\hookleftarrow}

\frac{2}{3}  \times  \frac{7}{4}  \\  =  \frac{2 \times 7}{3 \times 4}  \\  =  \frac{14}{12}  \\  =  \frac{7}{6}

You'll get the answer as 7/6 which is equal to <u>1</u><u>.</u><u>1</u><u>6</u>. 2/3 is equal to <u>0.66</u>.

•°•  \frac{7}{6}  >  \frac{2}{3}

✐ So, the answer is ⇻ <u>greater</u><u> than 2/3</u><u>.</u>

La suma de las edades de tres personas es 127años. La mayor tiene 30 años mas que la menor y la del intermedio 26 menos que la m
Over [174]

Answer:

La mayor tiene 61 años.

Step-by-step explanation:

Sea x,y,z la edad de la mayor, intermedio y la menor respectivamente.

Tenemos las siguientes ecuaciones:

x+y+z=127 (la suma de las edades es 127)

x = z+30 (la mayor tiene 30 años más que la menor)

La frase "y la del intermedio 26 menos que la menor" no tiene sentido, puesto que esto implicaría que la del intermedio es menor que la menor. Luego se asume que la frase ha de ser "y la del intermedio 26 menos que la mayor"

x-26 = y (la del intermedio tiene 26 menos que la mayor).

La segunda ecuación se traduce a x-30 =z. Si reemplazamos todo en la primera ecuación obtenemos

x+(x-26)+(x-30) = 127

Obtenemos la ecuación

3x-56 = 127

Sumando 56 a ambos lados y dividiendo por 3, obtenemos

x = \frac{127+56}{3} = 61

Es decir la mayor tiene 61 años.

WHAT IS THE SLOPE IF I HAVE (-3,5) AND (4,-5)
irina [24]

Answer:

-10/7

Step-by-step explanation:

Use slope formula

\frac{y2-y1} {x2-x1}

x1= -3

y1 = 5

x2 = 4

y2 = -5

\frac{-5-5}{4--3}

<h2>\frac{-5 + -5}{4 +3}</h2>

\frac{-10}{7}

The surface area of the box of cereal displayed is 2x^2+48x+88. What is the value of x if the box of cereal has a total surface
marissa [1.9K]

Answer:

x_2= \frac{-24 +28}{2}=2

And the correct solution would be x=2 since a negative value not have a practica interpretation on this case.

Step-by-step explanation:

For this case the surface area is given by this formula:

S (x) =2x^2 +48 x +88   (1)

For this case we have that the total surface area is 192, so we need to set up equal to 192 and solve for the value of x like this:

192= 2x^2 +48 x+88

We can set up the last equuation equal to 0 like this:

2x^2 +48 x-104 =0

We can divide both sides of the equation by 2 and we got:

x^2 +24x -52=0

Now we can use the quadratic formula in order to solve the value of x given by:

x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}

For our equation a = 1, b = 24 and c = -52 and if we replace we got:

x = \frac{-24 \pm \sqrt{(24)^2 -4(1)(-52)}}{2(1)}

And the two solutions are:

x_1 = \frac{-24 -28}{2}=-26

x_2= \frac{-24 +28}{2}=2

And the correct solution would be x=2 since a negative value not have a practica interpretation on this case.
