Answer:
m
2
−2m+3
Step-by-step explanation:
X = low-energy lamp
y = high-energy lamp
1) 4x + 5y
2) 120= 4x + 5y
we will check each options
option-A:
For solving any equations , we always isolate variables on anyone side
For exp: x+7=1
so, this is TRUE
option-B:
For solving system of equations
For exp:
x-y=1
x+y=3
If we use addition , we could easily solve for x and y
so, this is TRUE
option-C:
We always solve problems using conventional method
we do not guess
so, this is FALSE
option-D:
We often reverse order of operation
For exp:
(x-2)^2-3=0
so, this is TRUE
option-E:
For linear equations , we always get one solution , infinite solutions or no solutions
so, this is FALSE
Answer:
24 is the LCM of 4,6,8. I think thats what your looking for.
Hope this helps!
