Supplementary anglessssss
Answer:
180cm²
Step-by-step explanation:
Width = x
Length = 5x
x + x + 5x + 5x = 12x
72/12 = 6
x = 6
Width = 6
Length = 30
6 x 30 = 180cm²

Answer:
The solution is (-3, 10.8)
Step-by-step explanation:
While it's rather obvious that you want to solve this system of linear equations, you should share that instruction when you post the problem.
To solve this system using elimination by addition and subtraction, combine the two equations as shown below (to eliminate y):
-0.18x + y = -6.54
-2.8x - y = -2.4
--------------------------
-2.98x = -8.94
Dividing both sides by -2.98, to isolate x, yields: x = -8.94 / (-2.98) = -3.
Then x = 3. Find y from -2.8x - y = -2.4: -2.8x + 2.4 = y, and here,
y = -2.8(-3) + 2.4 = 8.4 + 2.4 = 10.8
Then the solution is (-3, 10.8)
Answer:
In order for the appropriate answer to be given, you need to include the original measurements as well.
