7x+y 11 and 2x+9y=-2.

Angle ���JKL and angle ���MKQ are complementary angles. The measure of angle ���JKL is twice the measure of angle ���MKQ. Write one equation to find  �x, the measure of angle  ���MKQ, and then solve for  �x. Enter your equation and solution in the space provided

Printer A can print Helen's class project in 18 minutes. Printer B can print the project in 30 minutes. If the two printers work together, how long would they take to print out the project?

Can you please solve -7x + 4y = 2 and 2x + 11y = -4. Please graph the solution as well.

x-2y=6 y=12x+9 solve by graphing please answer in typing format

Hannah walks dogs for four different families. She charges each family the same amount of money per hour. The numbers of hours she worked last week walking dogs for each of the families are shown. 1 hours, 2 hours, 1 hours, 3 hours Hannah earned $93 for the hours she worked last week walking dogs. 1) Calculate the amount of money Hannah earns per hour for walking dogs. 2) Write an equation that can be used to determine the amount of money, m, in dollars, Hannah earns when she works h hours walking dogs.
