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.

In GHI the measure angle I = 90° the measure of angle G = 5° and IG = 57 feet. Find the length of GH to the nearest tenth of a foot
Answer:
GH = 57.2 feet
Step-by-step explanation:
Given the following
m<I = 90 degrees
<G = 5 degrees
IG = 57 feet
Required
Length of GH
According to the data given
GH is the hypotenuse
iG is the adjacent side to m<G
Cos theta = adj/hyp
Cos 5 = IG/GH
Cos 5 = 57/GH
GH = 57/cos 5
GH = 57/0.9962
GH = 57.2 feet
Answer: 57.2 feet

The quotient of a number and -6 decreased by 2, is 10. FInd the number
Answer:
[tex]x = 48[/tex]
Step-by-step explanation:
Quotient means what you get when you divide a number by another number.
What we can do is make an equation using the information given, which turns out to be this:
[tex](\frac{x}{6}) - 2 = 10[/tex]
Add 2.
[tex]\frac{x}{6} = 8[/tex]
Multiply by 6.
[tex]x = 48[/tex]

On one night, a scientist needs to determine the
distance she is away from the International Space
Station. At the specific time she is determining this the
space station distance they are both on the same line of
longitude 77' E. Furthermore, she is on a latitude of 29°
N and the space station is orbiting just above a latitude
of 61.4° N. In short, the central angle between the two
is 32.4°. If the Earth's radius is 3959 miles and the
space station orbits 205 miles above the surface of the
Earth, then how far is the scientist away from the space
station?
205 mi
3959 miles
324 CE

Answer:
surface area =0.1357
Step-by-step explanation:
first, find the triangle area
to find use triangle area= base x height divided by 2
so .18 x .23
=0.0414
divided by 2
= .0207
multiplty 0.0414 by 4 because theres a total of 4 triangle sides
.0207 x 4 = 0.0828
now find the area of the square on the bottom
area= base x height
.23 x .23 = 0.0529
now add the two areas together
0.0529 + 0.0828= 0.1357
Hamburger Heaven is having a lunch special where customers buy one 1/4 pound cheeseburger and get one free. If they set aside 114 2/3 pounds of meat, how many -pound cheeseburgers can they make?
Answer: 459 cheeseburgers
Step-by-step explanation:
To find out the number of cheeseburgers that can be made, divide the amount of meat set aside by the amount of meat it takes to make one cheeseburger.
The amount of meat they have is:
= 114²/₃
= 344/3
Number of cheeseburgers is:
= 344/3 ÷ 1/4
= 344/3 * 4/1
= 1,376 / 3
= 458.67
= 459 cheeseburgers
select the correct answer if not watch out for your back mate

The answer is 1 day and 7 items.
Ariana
y = 5x + 2
Julie
y = 7x
The ys have to be the same so equate the right hand side.
7x = 5x + 2 Subtract 5x from both sides.
7x - 5x = 5x - 5x + 2
2x = 2 Divide by 2
2x/2 = 2/2
x = 1
