Write an expression for the calculation double the number 18 and then add 14 divided in half

Use the elimination method to solve the system of equations -x+5y=-4 and 4x+3y=16

Solve - pv + 40 < 65 for v solve 7w - 3r = 15 for r

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
