Answer:
Hello my friend! The first step is to isolate the x and the 40 like this: x2 = 40.
Step-by-step explanation:
After you do that, you can perform the inverse operation of the x2, wich is the sqrt of 40. This way, you will have x=sqrt40 . X~=6.32
Answer:
Option 1: 1430p + 2200 = -4001
Step-by-step explanation:
Given that:
1.43p + 2.2 = -4.001
We can replace:
1.43p by 1430p * 10^-3
2.2 by 2200 * 10^-3
-4.001 by -4001* 10^-3
So the equation will become:
1430p * 10^-3 + 2200* 10^-3 = -4001 * 10^-3
Taking 10^-3 common from both side
(1430p + 2200)* 10^-3 = -4001 * 10^-3
Cancelling 10^-3 from both sides we get:
1430p + 2200 = -4001

Answer:
the answer is 9
Step-by-step explanation:
why it 9 Add '2.7' to each side of the equation.
-2.7 + 2.7 + 0.3x = 9 + 2.7
Combine like terms: -2.7 + 2.7 = 0.0
0.0 + 0.3x = 9 + 2.7
0.3x = 9 + 2.7
Combine like terms: 9 + 2.7 = 11.7
0.3x = 11.7
Divide each side by '0.3'.
x = 39
Simplifying
x = 39
The answer is the first one
