- Relay teams
There are 159 students to be grouped into relay teams. Each team should have the same number of students. Can each team have 3,5 or 6 students? Explain. - Guadalupe
Guadalupe bought snacks for her team's practice. She bought a bag of chips for $1.93 and a 15-pack of juice bottles for a total cost before tax of $32.83. Write and solve an equation that can be used to determine x, the cost of each bottle of juice. - Two equivalent fractions
2/4= what over 12 - Dostaneli
If we get 5% of the amount that Petr has in his wallet and 4% of the amount that Paul has with him, we will have 46 CZK. However, if we get 4% from Peter's and 5% from Paul's, we will only have 44 CZK. How many crowns do Petr and Paul have with them? - Equation: 32
Equation: 4.7m = 43.71 To isolate the variable on one side of the equal sign, divide both sides of the equation by simplifying.
