No links please just answers thank you Determine if the values given for the variables are solutions to the following equations.
1. x = 4 and y = 8 for y = 3x - 4
2.m = 12 and n = 200 for n = 15m - 20
3.a = 5 and b = 48 for b = 8a + 8
4.g = 40 and h = 1000 for h = 25g + 300

Aparking lot is to be 400 feet wide and 370 feet deep. how many standard-sized cars fit in this lot considering a double-loaded (w4) two way traffic set up, an angle of 90° and a sw of 9’ 0’’? (do not consider handicapped parking spaces, and consider 15’ for turning aisles). show your work.

Solve the system of equations. y= 2x y= x^2 - 15
