. You have 8 minutes to exercise at the gm. The elliptical trainer burns 9 calories per minute, while the treadmill burns 8 calories per minute. You want to burn 00 calories total using both machines. How much time should ou spend on each machine?. A science teacher ordered $980 worth of microscopes and dissection kits for the new science lab. A total of 8 microscopes and 7 dissection kits were ordered. A microscope costs four times as much as a dissection kit. Write a sstem of linear equations that represents this situation. What is the cost of each item?. You have $6 to spend at the carnival one night. Shooting free throws costs $ per game, and plaing ring toss costs $ per game. You want to pla at least 6 games that night. a. Write and graph a sstem of linear inequalities that represents this situation. b. Identif and interpret one solution of the sstem.
