Answer:
The type of lamp is a confounding variable.
Step-by-step explanation:
to test the average life of the bulbs the same lamps should be used
- 6
- 14
- 12 4/5
- 2 2/3
Just division, fairly simple with or without a calculator.
The answer could be negative or positive. We are not given specific as to whether or not the starting number is positive or negative so therefore it could be either.
Hope this is helpful :)
Answer:
In a linear equation of one variable there are two terms terms containing variable and constant.
Variable means term containing x,y,z which act as variables. and constant means any rational number . In higher classes you can include real number also.
The given equation is 3x + 5x = 10
So, the solution out of four options is A) 5x = 20.
Here variable is on one side of equation and constant on other side.
But Option (D) looks absolutely correct if we replace ? by either + sign or Negative (-) sign.
Slope: 5/1 (5 if simplified)
y-intercept: 10
