The final step in this inequality is to make x the subject. To do this, we divide both sides of the inequality by -2. Whenever we mulitply or divide by a negative number in an inequality, we must swtich the sign. So the inequality becomes -6/-2 > -2x/-2 which simplifies to x < 3. The third option is correct.Hope this helps. Let me know if you need additional help!

Solve the inequality. 6(x/2 + 4)>9

Airida [17]

6(x/2 + 4)>9

x/2 + 4 > 9/6

x/2 + 4 > 3/2

x/2 > 3/2 - 4

2*(x/2) > 2*(3/2 - 4)

x > 3 - 8

x > - 5

Answer:

x = 12

Step-by-step explanation:

In a right triangle (a triangle that has a ninety degree angle in it) the the square of the side opposite the right angle is always equal to the sum of the squares of the other two sides. Therefore, we can use the information we are given to figure out the missing side:

$15^2=225\\9^2=81\\225-81=144\\\sqrt[2]{144}=12$
