X - the number of loads by land carriers,
y - the number of loads by air carriers;
The system of inequalities:
x + y ≤ 150
2,000 x + 1,250 y ≤ 180,000
X is shirt type 1, y is shirt type 2
x+y=5
<span>
5x+10y=35
</span>Use elimination.
solve for y
plug in y in one of the equations to find x
After x months Ian owes 1000 - 60x
After x months Ken owes 600 - 20x
They're equal when
1000 - 60x = 600 - 20x
400 = 40x
x = 10

Answer:
6. 300 m^2
Step-by-step explanation:
Volume of triangular Pyramid = V = 1/3AH, where A=Area of the base, H=Height. So,
300 =1/3A*3
300 =1/3*3*A
300 =A, or
Area of the base =300 m^2.
