Answer:
irrational because the square root of 51 is irrational.
You are told that B=3g-7 and you are also told that B=17 so
3g-7=17 add 7 to both sides
3g=24 divide both sides by 3
g=8
So Gabriela is 8 years of age.
46.94 ≈ 47
7.09 ≈ 7
10/40 = (10*1)/(10*4) = (10/10)*(1/4) = 1/4
We can solve it two ways, we´ll do it via physics:
We know that:
d=vt
d=770km/h*15h
d=11550km
Now at 660km/h:
t=d/v
t=11550km/660km/h
t=17,5h
Math way:
770km/h→15h
660km/h→x
So:
(770*15)/660=x
x=17,5h
Answer: 77 tickets
