Answer:

Andrés tiene 15 años y Alex tiene 12 años.

Step-by-step explanation:

Como el enunciado dice que dentro de 3 años, la edad de Alex será la edad que tiene ahora Andrés puedes escribir una ecuación que indique que la edad de Andrés es igual a la edad de Alex más 3:

x=y+3, donde:

x es la edad de Andrés

y es la edad de Alex

Además, como se indica que dentro 9 años, la edad de Andrés será el doble de la edad que Alex tiene ahora puedes escribir una ecuación que indique que la edad de Andrés más 9 es igual a dos veces la edad de Alex:

x+9=2y

Ahora puedes reemplazar x=y+3 en x+9=2y y despejar y:

y+3+9=2y

12=2y-y

y=12

Finalmente, puedes reemplazar el valor de y en x=y+3 para encontrar el valor de x:

x=y+3

x=12+3

x=15

De acuerdo a esto, la respuesta es que Andrés tiene 15 años y Alex tiene 12 años.

Answer:

rectangular prism = cuboid

total surface area of a cuboid (tsa) = 2(lb+bh+hl)

l=length = 3cm

b=breadth = 6cm

h=height = 5cm

tsa = 2( 3*6 + 6*5 + 5*3 )

        2( 18 + 30 + 15 )

         2 * 63

       = 126 [tex]cm^{2}[/tex]

hope this answer helps you.....

Answer:

132

Step-by-step explanation:

the ratio for saly is 4 out of 14. so 4/14 is 0.28571429. and if you multiply that by the total collected shirts which is 462, you get 132 :)))

Answer:

mean

Step-by-step explanation:

mean of six packages = (29+19+69+24+64+59)/6 = 44 ounces

Median of these six packages (19,24,29,59,64,69) = (29+59)/2 = 88/2= 44 ounces

Now, if we includes a package that weighs 219 ounces

The new mean = (29+19+69+24+64+59+219)/7 = 69

New median (19,24,29,59,64,69, 219) = 59

Hence, we say that the mean increases more than the median

Answer:

Convert to a mixed number by placing the numbers to the right of the decimal over

1000000

. Reduce the fraction. Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. Place this new numerator over the original denominator.

Answer:

large popcorn: $8

small drink: $3.75

= $8 + $3.75

= $11.75

Answer:

$11.75d

Step-by-step explanation:

add 8.00 and 3.75

you get 11.75 since U don't know how much it is for the drink, then U put d 11.75 so when U find d, you'll know that U can add it with your sum.

Step-by-step explanation:

Given

The given proportion can be represented as:

[tex]1\ bag = 4yd^2[/tex]

Required

The additional number of mulch needed

The question has incomplete details, as the amount of mulch he has applied and the area of the flower garden are not given.

So, I will make some assumptions to solve this question.

Let the area of his flower garden be x.

So, we have:

[tex]1\ bag = 4yd^2[/tex]

[tex]y = x\ yd^2[/tex]

Cross multiply

[tex]4yd^2 * y = xyd^2 * 1\ bag[/tex]

Make y the subject

[tex]y = \frac{x\ yd^2 * 1\ bag}{4yd^2}[/tex]

[tex]y = \frac{x* 1\ bag}{4}[/tex]

[tex]y = \frac{x}{4}\ bag[/tex] --- This represents the total amount of mulch required for the flower garden

--------------------------------------------------------------------------------------------------------

Assumptions

Assume that [tex]x = 16[/tex],

So, we have:

[tex]y = \frac{x}{4}\ bag[/tex]

[tex]y = \frac{16}{4}[/tex]

[tex]y = 4[/tex]

i.e 4 bags are needed.

Assume he has applied 2 bags already.

The number of bags needed to apply will be:

[tex]y - 2[/tex]

[tex]y - 2 = 4 - 2[/tex]

[tex]y - 2 = 2[/tex]

2 more bags needed

Answer:

  no

Step-by-step explanation:

The dimensions will be those of a rectangular mirror if the diagonal measure is the hypotenuse of the right triangle with the given side lengths.

The Pythagorean theorem would require for some width w ...

  w^2 +24^2 = 30^2

  w^2 = 900 -576 = 324

  w = √324 = 18

A rectangular mirror with a length of 24 inches and a diagonal of 30 inches will have a width of 18 inches, not 16.

__

The attachment shows that a width of 16 inches is not consistent with a right-angle corner.

_____

Additional comment

If you reduce the given numbers to lowest terms by dividing them by 2, they become 8, 12, 15. That is, the two shortest sides are even and the longest is odd. Any set of integer dimensions for a right triangle must have an even number of odd numbers (0 or 2). These numbers cannot be a Pythagorean triple, so cannot make a right triangle.

Answer:

70°

Step-by-step explanation:

Sum of angles in a parallelogram is 360°

Opposite angles are equal

2(16x - 2) + 2(8x + 14) = 360°

32x - 4 + 16x + 28 = 360°

32x + 16x + 28 - 4 = 360°

48x + 24 = 360°

48x = 360 - 24

48x = 336

x = 7

m< E = 8x + 14

Substitute for x

= 8(7) + 14

= 56 + 14

= 70°

Answer:

3.) x = 4.5

4.) y = 7

Step-by-step explanation:

3 is an easier one than 4. By the triangle midsegment theorem, the midsegment of a triangle will be half of the base if it is parallel to it. AB is our base, so the equation is like this!

[tex]AB = 2(ED)\\9=2(ED)\\4.5=ED[/tex]

Now for 4, it actually is pretty easy. By the same triangle midsegment theorem, we automatically know that EC and EA are congruent, and CD and DB are also congruent. Meaning y equals 7.

But another way we can determine this (the long, kinda unecessary, but useful way) is through examining the relationship that triangles ABC and EDC have!  We know that they are similar triangles by SAS or AA. Meaning, their equation looks something like this...

[tex]4.5(7+y) = 9y\\31.5 + 4.5y = 9y\\31.5=4.5y\\7=y[/tex]

Like I said earlier, 7 is equal to y, but I figured I'd prove it so we are on the same page. Nothing wrong with double-checking ;)
