Question

Найдите значение выражения -18+|a|-|b|, если a=-6, b=-7,2

Answer 1

-18+|a|-|b|=-18+|-6|-|-7,2|=-18+6-7,2=-19,2

Answer 2

To find the value of the expression -18 + |a| - |b| when a = -6 and b = -7.2, we simply substitute the values of a and b into the expression and perform the arithmetic.

First, calculate the absolute values of a and b:

|a| = |-6| = 6 |b| = |-7.2| = 7.2

Now, substitute the values into the expression:

-18 + |a| - |b| = -18 + 6 - 7.2

Next, perform the arithmetic:

-18 + 6 - 7.2 = -19.2

So, the value of the expression -18 + |a| - |b| when a = -6 and b = -7.2 is -19.2.
