Martha can complete 15 activities a day at summer camp she can choose between crafts and sports part a: define two variables and create an equation to represent the situation

15x2=30 combinations

Or x= activities a day

Y=crafts and sports

D=combinations

XxY=D

Step-by-step explanation: variables would be the activities per day and options of what to do. Multiply those to end up with the total number of combinations.

i do not know this sorry : (

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
