The temperature in San Diego, California, is 5 degrees warmer than twice the temperature in Boise, Idaho. The temperature in San Diego is 61 degrees. Write an equation to determine the temperature in Boise.
a. 2x − 5 = 61
b. 2x − 61 = 5
c. 2x + 61 = 5
d. 2x + 5 = 61
d. 2x + 5 = 61
George and his dad are planning to attend the state fair. An adult ticket is $19. The price of an adult ticket is one third the price of a student ticket plus $15. Write an equation to determine how much George will pay for a student ticket.
a. one third x + 19 = 15
b. one third x + 15 = 19
c. one third x − 19 = 15
d. one third x − 15 = 19
b. one third x + 15 = 19
A plant produces sport drinks, which must be within 0.32 fluid ounces of the advertised 16 fluid ounces on the label. If x represents the volume, write an equation to model the maximum and minimum volumes and determine the minimum volume in a bottle.
a. |x − 16| = 0.32; x = 15.68 ounces
b. |x + 16| = 0.32; x = 16.32 ounces
c. |x − 0.32| = 16; x = 15.68 ounces
d. |x + 0.32| = 16; x = 16.32 ounces
a. |x − 16| = 0.32; x = 15.68 ounces
John has consumed 1,600 calories so far today. He has also burned off 400 calories at the gym. He would like to keep his daily calorie total to 1,800 calories per day. How many calories does he have left to consume for the day? Is 1,000 a viable solution to this problem?
a. No; 1,000 is more than the 400 he burned off at the gym.
b. No; 1,000 will cause him to exceed 1,800.
c. Yes; 1,000 is less than 1,600.
d. Yes; 1,200 is less than 1,800
