Let x represent the number of baseball cards that Katerina owns. Peter has 7 more cards than Katerina, and together they have 51 cards. Which equation can be used to find the number of baseball cards that Katerina owns?

• 2(x + 7) = 51

• x = 51 ÷ 7

• x + 7 = 51

• x + (x + 7) = 51

Jorge goes for a run after school. He walks 0.28 miles to warm up and then runs at a constant rate of 7.1 miles per hour for m minutes. After his run, he walks 0.3 miles to cool down. In total, Jorge walks and runs 3.42 miles. Which equation can be used to find how many minutes Jorge runs?

• ^71m+.58=3.42

• 7.1/60m + .58= 3.42

• 7.1(m+.58)=3.42

• 7.1/60 (m+.58)=3.42

A weather balloon is launched in Texas from an altitude of 240 feet above sea level. If the balloon rises at a constant rate of 65 feet per minute, which of the following equations could be used to find t, the time in minutes it will take the balloon to reach an altitude of 11,000 feet?

• 11,000 = 240t + 65

• 11,000 = (240 + 65)t

• 11,000 = 65(t + 240)

• 11,000 = 240 + 65t
