Answer: the second answer

Step-by-step explanation:

If we want to find an inequality with no solution, that means we can expect no x and an unbalanced inequality (e.g., 3<0 which is untrue).

The second one is like that because the inequality is

3+4x\leq2(1+2x)

If we solve it out, we get

3+4x\leq2+4x

When you remove the variable from both sides, you now have

3\leq2

This statement is false, since 2 will never be greater than 3.

If we look at the others, we can see that there are answers for all of them.

1. the sum of two rational numbers is always always a (irrational number / rational number)
Blizzard [7]

One

The sum of two rational numbers is always rational. sqrt(9) + sqrt(25) = 3 + 5 which is rational. sqrt(16/100) = 4/10 = 2/5 is also rational. 3/28 is rational as well.

Two

Those are irrational. sqrt(10) + pi = ???? You cannot reduce this to any kind of fraction. Two irrationals always give a rational.

Three

The irrational number controls the answer. 10 + sqrt(5) is irrational. The 10 is OK. It is raional, but sqrt(5) is not a rational number.

zhenek [66]

Answer:

\large \boxed{\text{A. 3.0 h}}

Step-by-step explanation:

The bill          = $190

Less flat fee  =    25

Work done   = $165

\text{Hours worked} = \$165 \times \dfrac{\text{1 h}}{\$55} = \textbf{3.0 h}\\\\\text{The electrician was on the job for $\large \boxed{\textbf{3.0 h}}$}
