i can't see it sorry
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
b
Answer:
Step-by-step explanation:
a + b/x = W
b/x = W - a
b = Wx - ax
The first thing we must do for this case is to define a variable:
x: number of years
y: total salary
We have then:
For first company:
y = 1500x + 31000
For second company:
y = 2000x + 28500
Equaling both equations we have:
1500x + 31000 = 2000x + 28500
Clearing x:
2000x - 1500x = 31000 - 28500
500x = 2500
x = 2500/500
x = 5
Answer:
It will take for the salaries to be the same about:
x = 5 years
Given:
First, just leave the negative sign at the side. You will deal with that later. For now, you focus on solving on the square root of 25. The square root of 25 is a number that when multiplied with itself, equals to 25.
For example, 4x4=16. So, the square root of 16 is 4.
Now, for 25, the answer would be 5. Since 5x5 = 25.
Then, you take the negative sign with the 5. The answer would be
-5.
