Answer:
x = 11
Step-by-step explanation:
2(x - 5) = 12 ← divide both sides by 2
x - 5 = 6 ( add 5 to both sides )
x = 11
Answer:
13.5
Step-by-step explanation:
2/3=9/x
2x=9*3
2x=27
x=27÷2
x=13.5
The solution is the point where the lines cross. So (-1, -2)
Answer:
Step-by-step explanation:
So we have the equation:
And we want to solve for R.
First, let's multiply both sides by J to remove the fraction on the right. So:
Simplify the right:
We can rewrite our equation as:
So, to isolate the R variable, divide both sides by I²t:
The right side cancels, so:
And we are done!
The answer is 2 feet it is equal to two feet
