In Unit 3, we're going to bring it up a notch, and test how you can solve one step equations. Feel free to try out any problems, and check your answers in the new answer key!
12 pineapples are planted into the soil. 5 of them are ripe and x others are not ready yet.
• Write an equation modeling this problem.
•How many pineapples are not ready yet?
A pod of dolphins swims near the coast of Maui. There are 20 of them in total. In the pod, there are d male dolphins and 7 female ones.
• Write an equation modeling this problem.
• How many male dolphins are there now?
A basket of coconuts is placed in a nearby taro field. There are c coconuts total. They are arranged in 5 rows of 7. How many coconuts are there total?
A local decides to sail 10 miles out to see. He does not remember how many miles he has completed (m), but his map says there are 2 miles left. How many miles or m has he already sailed?
A green sea turtle has just laid her eggs on the shore. She has a total of 108 eggs. A third of her eggs are bigger than the others. The other 72 are a normal size. Give two different equations that could model this problem. Use the variable t.
The box of coconuts from problem 3 now has 2 more rows of 7 added. They are placed in a truck with other coconuts. They now have 98 coconuts in total. Calculate how many coconuts were in the truck before the new ones arrived. Use c for your variable.
