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
Im not sure but I think it’s Y/2-2 (the y and 2 is a fraction)
Convert it into an improper fraction. Find your common denominator then subtract. If this doesn’t help let me know.
