Question

−0,2h+9=−3 дам 30 баллов

Answer 1

Ответ:

h=60

Объяснение:

-0,2h= -3-9

-0,2h= -12

h= -12÷(-0,2)

h=60

Answer 2

To solve the equation −0.2h + 9 = −3, we'll isolate the variable h on one side of the equation. Here's the step-by-step solution:

−0.2h + 9 = −3

Subtract 9 from both sides: −0.2h = −3 − 9 −0.2h = -12

Now, we'll divide both sides by −0.2 to solve for h: h = (-12) / (-0.2) h = 60

Therefore, the solution to the equation is h = 60.

As for the "30 баллов" mentioned, it seems like a separate statement, but without additional context, it's unclear how it relates to the equation or solution provided.
