1.Translate the sentence into an equation.

Two hundred minus three times a number is equal to nine.

 

200 - 3n = 9

3n - 200 = 9

3(200 - n) = 9

(200 - 3)n = 9

2. Translate the sentence into an equation.

The sum of one-third a number and 25 is as much as twice the number.

 

â…“(n + 25) = 2

(â…“)n + 25 = n

3n + 25 = 2n

(â…“)n + 25 = 2n

3. The Pacific Ocean covers about 46% of the Earth. If P represents the area of the Pacific Ocean and E represents the area of Earth, write an equation for this situation.

 

E - 46 = P

46E = P

E - 0.46 = P

0.46E = P

4. Mrs. Patton is planning to place a fence around her vegetable garden. The fencing costs $1.75 per yard. She buys f yards of fencing and pays $3.50 in tax. If the total cost is $73.50, how many yards of fencing does she buy?

 

1.75f + 3.50f = 73.50

1.75 + 3.50f = 73.50

1.75f + 3.50 = 73.50

1.75 + 3.50 + 73.50 = f
