Your equations would be
c+d=10
5c+6d=56 (c= # of cats, d= # of dogs) Then solve
I am using elimination and multiply the first equation by -5
-5c-5d=-50
5c+6d=56
Then eliminate
-d=-6 Divide by -1 d=6
Then solve for c
c+6=10
c=4
Hope this helps!
Answer:
Square = 100
Small rectangle = 10
Step-by-step explanation:
Large Rectangle = 1000
If the square represents ten times the large rectangle. Then divide by 10.
Square = 100
Then divide by 10 again.

Answer:
There is enough paint to cover the tank with one layer of paint.
Step-by-step explanation:
Given the cilindrical configuration of the tank and supposing that only external face must be painted, the surface area of the section (lateral wall + lid) can be calculated by the following expression:
Where and represent the radius and the height of the cube, respectively.
If (a diameter is two times the length of radius) and , the intended surface area is:
It is known that 250 mL of paint are needed to cover a square meter of the surface area, the needed amount of paint to cover the required area is estimated by simple rule of three:
In consequence, there is enough paint to cover the tank with one layer of paint.
