Answer:
-18+12
Step-by-step explanation:
Answer:
-19
Step-by-step explanation:
Take the second term and subtract the first term to find what we are adding (or subtacting ) each time
-7 -(-3) =
-7+3
-4
We are subtracting 4 each time
Subtract 4 from the next term
-15 -4 = -19
The next term is -19
Well, we know that 3:1 is one batch of orange water. We also know that there are 2 things to focus on.
1. Must write ratio for 2 batches of the recipe.
2. Must write ratio for 4 batches of the recipe.
To make this equation simple, double the ratio to find 2 batches because all it means is 2x more water.
3:1
x2
6:2
So, the ratio would be 6:2 to make 2 batches.
To make it easier again, we just multiply the ratio of 2 batches by 2 which would find the ratio for 4 batches.
6:2
x2
12:4
So that means, that it is 6:2 for 2 batches, and 12:4 for four batches.
