The Estrada family's pancake recipe uses 2 teaspoons of baking powder for every of a teaspoon of salt. How much baking powder would they need if they used 1 teaspoon of salt?

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
