Answer:
m = 3, n = -2.
Step-by-step explanation:
Substitute n = 3m - 11 in the second equation:
2m + 3(3m - 11) = 0
2m + 9m - 33 = 0
11m = 33
m = 3.
Substitute for m in n = 3m-11:
n = 3(3) - 11
n = -2.
Answer:
No solution
Step-by-step explanation:
Distribute
5x+45 = 3x+24+ 2x
Combine terms
45=5x-5x
45=0
This statement is not true so it is no solution
Answer:
Answers are below in bold.
Step-by-step explanation:
The first answer is correct. 1 m² = 10,000cm²
A=2(wl+hl+hw) To find the surface area of the package, use this equation
A=2(18*50+20*50+20*18) Multiply in the parentheses
A=2(900+1000+360) Add in the parentheses
A=2(2260) Multiply
A=4520
The package has a surface area of 4520 cm²
The area of the package is less than the area of the wrapping paper.
So, Dayson can completely cover the package with the wrapping paper.
If it moves 29.9 meters a day, then we need to find the total amount of days:
1000 days + 100 days = 1100 days
Since it moves 29.9m per day, we can write:
29.9m x 1100 which equals 32 890m
So it moved 32 890m
