What is the solution to this system of equations?

1/4x + 1 and 1/2y = 5/8. 3/4x - 1 and 1/2y = 3 and 3/8

A) (4, -1/4)
B) (4, -9/16)
C) no solution
D) infinitely many solutions

How do i start to solve? would appreciate a walk-thru! a bird sitting 16ft above the ground in an apple tree dislodges an apple. after how many seconds does the apple land on the ground? (assuming that no branches will interfere with it's fall)

Tom drove 206 miles in 3.9 hours. estimate his average speed.

Scenario: susan wants to make 2 square flags to sell at a crafts fair. the fabric she wants to buy is 3 meters wide. she doesn't want any fabric left over. what's the least amount of fabric she should buy? question: which equation will susan solve her problem? note: let x represent the length of 1 side of the flag. options: 1) 2x^2 = 4x 2) 8 +2x = 2(4x) 3) 2 * 2 = 4 * 2 4) 4x^2 -2x = 0
