Mr. maddox asked four students to create a number line to find the sum of fractions 3 2/3 + 1 3/4 + 2/3

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6

Find an bif a = {3, 6, 9, 12) and b = {2, 4, 6, 8, 10).

What is the solution for 6 - 7/8? explain the steps.
