Answer:
y = 8 + x or
Keesha.cousin.age = 8 + Keesha.age
Step-by-step explanation:
II. When Keesha.cousin is older than Keesha 8 years
Give y = 8 + x, when y is Keesha cousin.age, x is Keesha.age
y = 8 + x
II. Prove by given Keesha is 10 years old.
y = 8 + 10
y = 18 or Keesha cousin is 18 years old.
Hope that help :)
Bike: 3/8 x3=1.125
Walk: 3-1.125=1.875
He walked 1.875 miles
He rode his bike 1.125 miles
Answer:
Step-by-step explanation:
I'll draw a quick sketch. It's hard to "see" this kinda of problem w/o a drawing , so start there. just draw as much as you can from what the problem tells you.
diameter = 14 cm
radius = 7 cm
pi = 3.142
PRQ = 35 °
to find Y use law of sines
sin(70) / Y = sin(55) / 7
sin(70) / sin(55) / 7 = Y ( I'll use my calculator for all the non standard angles )
sin(70) * 7 / sin(55) = Y ( and invert and multiply the fraction in the denom )
8.03007 = Y
x = 70 °
if you have questions, and you should, just put them in the comments , I'll see them later :)

Answer:
El 40% de los estudiantes reprobaron la asignatura.
Step-by-step explanation:
Dado que sabes el número total de estudiantes y cuántos aprobaron la asignatura, puedes restar el número de estudiantes que aprobaron del total de estudiantes para encontrar los estudiantes que reprobaron la asignatura:
50-30=20
Ahora puedes calcular el porcentaje dividiendo el número de estudiantes que reprobaron entre el total de estudiantes y multiplicando el resultado por 100:
20/50*100=40%
De acuerdo a esto, la respuesta es que el 40% de los estudiantes reprobaron la asignatura.
