Answer:
0.1575 the fraction is 63/400, just divide 63 by 400
-by-step explanation:
Two inequalities are equivalent if they have the same set of solutions.
x - 5 ≤ 6 - 5
x - 5 ≤ 1 |add 5 to both sides
x ≤ 6
It would b because you would use a calculator to figure out the square root and then which is that number between
Answer:
Just multiply:
= 0.06×0.021
= 1.26
is this the right answer I don't even know my answer
Answer:
x = 23; not extraneous
Step-by-step explanation:
A solution is extraneous if it does not satisfy the original equation. Extraneous solutions can sometimes be introduced in the process of solving radical and rational function equations.
<h3>Solution</h3>
Squaring both sides of the given equation, we get ...
√(3x +12) = 9
3x +12 = 81 . . . . . . square both sides
x +4 = 27 . . . . . . . divide by 3
x = 23 . . . . . . . . . . subtract 4
<h3>Check</h3>
There is only one solution, and it satisfies the equation:
√(3×23 +12) = √81 = 9
The solution x = 23 is not extraneous.
