Solve the inequality for x -11 < -18- 7/9x
zavuch27 [327]

The solution of the inequality is x < -9

<h3>How to solve the inequality for x?</h3>

The inequality expression is given as:

-11 < -18- 7/9x

Add 18 to both sides of the inequality

18 - 11 <- 7/9x

Evaluate the difference

7 <- 7/9x

Multiply both sides by -9/7

-9 < x

Rewrite as:

x < -9

Hence, the solution of the inequality is x < -9

Find three consecutive EVEN integers such that the sum of the smallest number and twice the middle number is 20 more than the la
nordsb [41]

define the 3 numbers

smallest number = x

middle number = x + 2

largest number = x + 4

write the equation

sum of the smallest number and twice the middle number

\begin{gathered} x+2(x+2) \\ x+2x+4 \\ 3x+4 \end{gathered}

20 more than the largest number

\begin{gathered} x+4+20 \\ x+24 \end{gathered}

equal the expressions

\begin{gathered} 3x+4=x+24 \\ 3x-x=24-4 \\ 2x=20 \\ x=\frac{20}{2} \\ x=10 \end{gathered}

the numbers should be 10, 12 and 14

\begin{gathered} 10+2\cdot(12)=14+20 \\ 10+24=34 \\ 34=34 \end{gathered}
