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:

2. 130; obtuse
3. 50; acute
4. 108; obtuse
Step-by-step explanation:
A.) 5(6x) = 30x B.) 2x+5y+7x= 9x+5y C.) 4(2x+5y)= 8x+20y
Answer: 6y I think. If you would have to add all of the y’s and so you would have 3 y’s and then you add both 3 y’s so 6y
I don’t know if I am right sorry if I’m wrong
