Let us say the dog eats x pounds of dog food in one month.
There are 12 months in a year.
So applying unitary method:
Quantity of dog food required by dog in 12 months = 12x
Answer : The dog requires 12x pounds of dog food in a year.
Actually I'm not so sure how to do this, but I think khan academy has something on this topic. Go check it out
D=√(x₁−x₂)²+(y₁-y₂)²
The picture below is the answer:
Answer:
a taco is 1.25 and a drink is 0.95
Step-by-step explanation:
tacos = t
drinks = d
5t + 3d = 9.10
3t + d = 4.70
this is a simultaneous equation so times the first one by one and the second by 3 and then take them away from each other and solving to get
t = 1.25 and d=0.95
one drink is $0.95
one taco is $1.25
Hope this helps!!
