Which equation, when solved, gives 8 for the value of x? a. 5/2x +7/2=3/4x+14 b. 5/4x-9=3/2x-12 c. 5/4x-2=3/2x-4 d. 5/2x-7=3/4x+14

Give all possible names for the line shown. calculation tip: lines can be written with either point first.

Acar started driving from city a to city b, distance between which is 620 miles, at a rate of 60 mph. two hours later a truck left city b and started moving towards city a at a rate of 40 mph. what distance from city a is the point where the truck and the car will meet?

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
