$25 per week. How many weeks will it take for them to earn a total of $275?
To start, record what you know.
Describe what you need to find.
Lisa earns $30 per week.
Beth earns $25 per week.
Total earned: $275
an equation to find the number of
weeks it takes to earn $275 together
10. The angles of a triangle are in the ratio 2 : 12 : 16. The sum of all the angles in a
triangle must equal 180 degrees. What is the degree measure of each angle of the
triangle? Let x = the common factor.
11. What two consecutive numbers have a sum of 53?
Determine whether the equation is always, sometimes, or never true.
12. 3(2x − 4) = 6(x − 2)
13. 4(x + 3) = 2(2x + 1)
