(Please help I don't know how to do this) If 16x + 16x - 1 = 10, find 22x.

If a2 - b2 = 8 and a*b = 2, find a4 + b4

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x

Drag each equation to the correct location on the table. for each equation, determine the number of solutions and place on the appropriate field in the table.

The students at jefferson middle school are raising money for a charity by selling t-shirts and hats. the number of t-shirts sold was 3 times the number of hats. the profit was $5 for each t-shirt sold and $2.50 for each hat sold. the students raised $840 for the charity. they used the system below to analyze their success and found the solution to be (144, 48). 5x+2.50y=840 x=3y how much did they earn from t-shirt sales?
