Let x represent the number of lawns mowed and y represent the number of cars washed.
1. Since the number of cars that Beth wash is no more than four times the number of lawns Mike has scheduled to mow, then y≤4x.
2. If Beth will wash at least 50 cars, then y≥50.
3. Mike charges $25 each time he mows a yard, so for x yards he will get $25x. Beth charges $15 for each car she washes, then the total amount of money she earns is $15y. Altogether they get $(25x+15y) that is at least $1975. This means that 25x+15y≥1975.
4. You get three inequalities:
You can use
Since it is an irregular triangle.
C refers to the angle and a & b refer to the adjacent sides.
So,
