Question

conan draws 6 cars in art class. rosa draws 7 cars. alec draws 7 cars. how many cars do they draw in all? image of two grids with colored circles complete the addition equation for the problem. 7 + blank + blank = 20

Explanation:

Step1: Identify the number of cars each drew

Conan drew 6 cars, Rosa drew 7 cars, Alec drew 7 cars.

Step2: Set up the addition equation

We know one of the numbers is 7 (either Rosa or Alec), then we need to fill in the other two numbers. Since Conan drew 6 and the other is 7 (the remaining of Rosa or Alec), the equation is $7 + 6 + 7$.

Step3: Calculate the sum (to verify)

$7+6 + 7=20$ (though the problem just needs the equation filled, but we can check).

Answer:

The addition equation is $7 + 6 + 7 = 20$, so the two blanks are 6 and 7 (or 7 and 6, but following the given start of 7, the next is 6 and then 7). So filling the blanks: 6 and 7.
