Answer:
The area of the shape is 3m³ square centimetres.
Step-by-step explanation:
We know that the area of single square is m² cm².
There are m squares per row, so for the area of the row, we multiply that by m, giving us m³ cm².
Finally, we know that there are three rows, so we need to multiply that by three, giving a total area of 3m³ cm²
For the given equation 45-n=15,
We have to create word problem.
Jason has 45 candies. After distributing 'n' candies to his friends in his birthday party, 15 candies are left with him. Which equation will find the number of candies he distributed to his friends in his party?
This word problem clearly matches to the given equation.
We can solve the system of equations to check the number of system of the solutions.
y=-6x+2 ...(1)
-12x-2y=-4 ...(2)
Substitute -6x+2 for y in equation (2). So,
-12x-2(-6x+2)=-4
-12x+12x-4=-4 (By distribution property).
-4=-4 (-12x and +12x has been cancel out).
Notice x has vanish from the above equation and we are left with -4=-4 which is correct.
So, the system has infinte number of solutions.

Step-by-step explanation:
Answer:
x=-12.5
Step-by-step explanation:
divide both sides
-0.2/(-0.20)=2.5/(-0.2)
x=2.5/(-0.2)
x+-12.5
