Answer:
Step-by-step explanation:
Z is the variable in this equation in this problem that we are looking for. Since z is next to the number 3. That means that whatever z is, it will be multiplied by 3.
3z = 36
The number we are trying to match is 36, so what times 3 equals 36?
Just do backwards equation,
z = 12
3(12) = 36

Answer:
1. 4
Step-by-step explanation:
For question 1, you need to know the ratio between the recipe and the amount in question.
So if in the recipe, it says it uses 3/4 cup of diced ham, and the question uses 1 cup of diced ham, you can divide 1 by 3/4 to get 4/3. This is how many times bigger the amount used in the question than the recipe.
Then it asks for how many cups of potatoes, to do this, you look at the recipe and how many potatoes it uses: 3.5 cups
To solve it then, you just do 3.5 x 4/3 to get 4 cups of potatoes
There's your answer.
