Answer:
(20 + 60) + (3 + 7) + (0.4 + 0.3) + (0.05 + 0.01)
Answer: 2461.76 cubic feet
Step-by-step explanation:

Answer:
x = 15
Therefore, the length and width are 31 and 47.
Step-by-step explanation:
Perimeter = (2x + 1) + (2x + 1) + (3x + 2) + (3x + 2) = 156
Simplified,
10x + 6 = 156
Subtract 6 from both sides, then divide by 10.
10x = 150
x = 15
To find the length and width, substitute 15 (the value of x) into the individual equations.
2(15) + 1 = 31
3(15) + 2 = 47
The first thing to do in this case is to graph both equations
y = 2x +1
y = / x /
Once graphed, you must evaluate points in the Cartesian plane that satisfy the inequations to know where the solution set is.
For this case, the solution set is in the shaded region, or equivalently, quadrants 1 and 2.
answer quadrants 1 and 2.
