Number 5. If $4.80 is 8% we want to know what is 100%. Since the 100% we are looking for is greater then we would divide 100/8=12.5. This means that 100% is 12.5 times the value of 8% in which the answer is $4.80.
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:
y = 7
Step-by-step explanation:
1) Substitute X with 1
9 ( 1 ) - 2y = - 5
2) Simplify 19×1 to 9
9 − 2y = −5
3) Subtract 9 from both sides
−2y = −5 − 9
4) Simplify −5−9 to −14
−2y = −14
5) Divide both sides by −2.
y = -14 / -2
6) Two negatives make a positive.
y = 14 / 2
7) Simplify 14 / 2 to 7
y = 7
