Answer: 9x - 4
Step-by-step explanation:
We know that a number must be decreased by four. Let's break it up a little.
Nine times <em>some </em>number. We don't know what nine will be multiplied by, so we will just write a placeholder number: x. This number will be multiplied by nine. So it will turn into 9x.
We must decrease (subtract) from this by four. Subtracting 9x by four can be written as 9x - 4.
Okay. Mainly for these questions, we have to write out equations.
1. For the vacation days given in the U.S., that equation would be 25-n, because the U.S. gets fewer days than the Japanese worker does.
Equation: 25-n
2. The equation for this one would be 26s, because there are 26 grams of protein for each cup of cottage cheese. To find out the total amount of protein for all of the cups together, that equation works work out.
Equation: 26s
Answer: C. Independent equations.
