Answer:
There is no way to predict this because it could take her anywhere from 11 to 66 tries
Train 1 = (x) = 357.1 mph
Train 2= (x + 5.9) = 363 mph
let
x-------> walnuts that Mario eats in a week
y-------> walnuts that Yolanda eats in a week
we know that
x=2y-------> equation 1
y=6*7-------> y=42 walnuts
substitute the value of y in equation 1
so
x=2*42-----> x=84 walnuts
therefore
the answer is
Mario eat in a week 84 walnuts
Answer:
a. 146
Step-by-step explanation:
{4*[72-6*(3+2)]}-22
=[4*(72-6*5)]-22
=[4*(72-30)]-22
=(4*42)-22
=168-22
=146
560+ 147= 707
14(40)= 560
14+ 14(1/2)=21
21(7)= 147
