Explain what the inequality --4h <-14 represents. What value of h makes the equation true

KonstantinChe [14]

Answer:

-4h < - 14

We solve for h by applying the inverse operations;

The inverse operation of multiplication is division, so we divide by -4 on both sides;

/-4 /-4

h < 3.5, it could be 3.4, 3.3, 3.2 3.123, 2.4, 2.576, there are tons of numbers below 3.5.

So anything below 3.5 would best be suitable for the equation.
