Step-by-step explanation:
It would be six because they are like terms.
Answer: The dimensions of the flower bed are,
39 ft, 57 ft and 78 ft.
Step-by-step explanation: Of the three sides, one side is twice the length of the shortest. Let the shortest side be labelled as b. That means one of the sides of the flower bed measures twice b, that is, 2b.
Also we are told that the third side measures 18 feet more than the shortest side, b. The third side can now be represented by b + 18.
So the triangle has sides
b, 2b and b + 18
If the perimeter is 174, then
b + 2b + (b + 18) = 174
b + 2b + b + 18 = 174
4b + 18 = 174
Subtract 18 from both sides of the equation
4b = 156
Divide both sides of the equation by 4
b = 39.
Therefore the shortest side of the triangle measures 39 ft while the other two sides measure 78 ft (twice the length of b) and 57 ft (18 ft more than the shortest side)
Answer: A.
Step-by-step explanation:
The decimals are correctly lined up in answer choice a. Having no zero is the same as having one.
We can simplify each equation and find the solution.
6x + 2y = 15 can't be simplified further.
- 8x - 3y = 2 can't be simplified further.
4x - 4y = 6 on simplification gives 2x - 2y = 3 or x - y = 3/2
But, it does not coincide with the given equation.
- 3x + 3y = 6 on simplification gives x - y = - 2 coincides with the given equation.
Hence, - 3x + 3y = 6 can pair with x - y = -2 to create a consistent and dependent system.
