7. a plane flying from city a to city b travels x miles per hour for a total

of 4.5 hours. the plane takes the same route on the return trip, traveling

25 miles per hour faster for a total of 4.25 hours. what is the total distance

that the plane travels?

Solve the system by the elimination method. 3x - 2y - 7 = 0 5x + y - 3 = 0 to eliminate y, the lcm is 2. which of the following is the resulting equations? 1.3x - 2y - 7 = 0 5x + y - 3 = 0 2.3x - 2y - 7 = 0 -10x - 2y + 6 = 0 3.3x - 2y - 7 = 0 10x + 2y - 6 = 0

Use the distributive law to multiply. 3(4x + 5y + 6)

List the sides of δrst in in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12°
