Answer:
3
days
Step-by-step explanation:
Let the amount of work be x.
Daniel:
10 days = x
1 day = 
x
Father:
6 days = x
1 day = 
x
Together:
1 day = x + x
= 
x + 
x
= 
x
= 
x
No. of days = 
x ÷ x
= x × 
x
= 
= 3
Answer:
a ratio of cats to dogs is 5:3 so the total of that ratio is 8 so for every 8 animals there are 5 cats so 5/8*104=65
b. ratio of dogs to cats is 3:5 so 3 of every animal is a dog so 3/8*104 =39
and 39+65=104 as a final check = 104
this also proves that dogs are better than cats
Step-by-step explanation:

Step-by-step explanation:
many things are possible.
the only thing we must not do is mixing the addition elements with the multiplication elements.
but we could change the expression to
3×(3×8) + 5
or
5 + (3×3)×8
or
5 + (3×8)×3
and so on, and it would always be the same result.
Hi there!
From the given information, we can infer that the inner quadrilateral has equal side lengths of x and 2x-3.
We can turn this into a mathematical equation with 1 variable.
x = 2x - 3
Subtract both sides by 2x
-x = -3
Multiply both sides by -1
x = 3
Have an awesome day! :)
