Solve for x:   [answer1]  A shaded four-sided figure is shown. The top side, labeled from A to B, and the bottom side, labeled from D to C, have matching arrow marks indicating they are parallel. The top-left angle at A is labeled 4x plus 60, and the top-right angle at B is labeled 10x minus 45. The bottom-left angle at D is labeled 4x, and the bottom-right angle at C is labeled 5x. The left and right sides slope outward from top to bottom, forming a wider base than top.

Find the value of x and y.  [answer1]  [answer2]  Two parallel diagonal lines are marked with matching arrow indicators, showing they run in the same direction. A transversal line intersects them at points T (left intersection) and B (right intersection). The transversal, also labeleld with a cursive lowercase l, extends from point V on the left through T and B to point C on the right. The leftmost parallel line, also labeled with a cursive lowercase m, extends from point S at the top through T to point U at the bottom, while the rightmost parallel line, also labeled with a cursive lowercase n, extends from point A at the top through B to point D at the bottom. The intersections form multiple angles where angle BDT is labeled (5y+7)°, angle UTV is labeled (7x-12)°, and angle VTS is labeled 73°.

Pop a Wheelie bicycles finds that 1 out of every 80 wheels they manufacture has a defect. If they manufacture 320 wheels per year, about how many can they expect to have a defect?  [answer1] wheels

Find the measure of angle MAP and angle PAE, if angle MAE is a right angle.  [answer1]  [answer2]  An angle diagram is centered at point A. A vertical ray extends upward from A to point M, and a horizontal ray extends right from A to point E. A third ray extends from A upward and to the right, passing through point P. The angle between the vertical ray and the slanted ray is labeled (2x + 1)°, and the angle between the slanted ray and the horizontal ray is labeled (8x − 11)°.

Circumference = [answer1] km (Round to the nearest tenth, if necessary.  Use 3.14 for pi.)

Tushar bought a car for $12,000. Two years later, after completing many repairs and upgrades, he sold the car for $18,000.  Find the percent of increase. 

Which proportion correctly relates the measurements from the similar figures?    The smaller pentagon MNOPQ is on the upper left. The vertices start with M at the top and proceed clockwise around the figure with N, O, P, and Q. Side MQ is labeled 6 cm, and side QP is labeled 10 cm. The larger pentagon ABCDE is on the bottom right with the same orientation. The vertices start a tthe top with A and proceed clockwise aroud the figure with B, C, D, and E. Side AE is labeled 8 cm, and side ED is labeled x.
