Building a is 190 feet shorter than building
MaRussiya [10]
We will solve this using a system of equations.  The first part tells us that building a is 190 feet shorter than building b.  Our first equation, then, is b=190+a.  The second part tells us that the addition of the two buildings' heights is 1480.  So our second equation is a + b = 1480.  The first equation is already solved for b, so let's sub that value into the second equation for b: a+(190+a)=1480.  2a + 190 = 1480 and 2a = 1290.  That means that building a is 645 feet tall.  Building b is 190 feet taller, so b = 190 + 645, which is 835.

Help me plz I’ve never been good with math
S_A_V [24]
Its 16.

So you have 12 miles on that trail, and markers every 2/3 of the way there. If you were to divide 2 with 3 then you can get the decimal of the fraction. Which in this case it’s 0.75. So every single 0.75 of the mile there is a marker. Divide 12 with 0.75 and you get 16 markers.


Hoped this helped in some way.

en el año 5 antes de Cristo, un chico cumplió 13 años.¿en qué año nació?, ¿en qué año nació su madre si lo tuvo con 22 años?
ki77a [65]

Answer:

El chico nació en el año 18 antes de cristo.

La madre nació en el año 40.

Step-by-step explanation:

Las respuestas son fáciles:

- Si en el año 5, el hijo tiene 13 años, hagamos que a partir del año 0 después de cristo sea positivo.

-13-(-5) = -18

- Madre:

-18-22 = -40

Entonces, su edad debería ser negativa, simplemente cambiamos el símbolo y lo pasamos a positivo.
