Question

|х|=2,6+(-1 целая 3/4)+(+3 целых 2/5)+(-0,25)

Answer 1

$|x|=2,6-1 \frac{3}{4}+3 \frac{2}{5} -0,25 = 2,6 - 1,75 + 3,4 - 0,25 = 6 - 2 = 4$

|x| = 4

x₁ = 4
x₂ = -4

Answer 2

To solve the expression |х|=2,6+(-1 целая 3/4)+(+3 целых 2/5)+(-0,25), let's break it down step by step:

1. Simplify the mixed numbers: -1 целая 3/4 = -1 - 3/4 = -1 - 0.75 = -1.75 +3 целых 2/5 = 3 + 2/5 = 3 + 0.4 = 3.4

2. Substitute the simplified values back into the expression: |х| = 2.6 + (-1.75) + (3.4) + (-0.25)

3. Perform the addition: |х| = 2.6 - 1.75 + 3.4 - 0.25 |х| = 2.6 - 1.75 + 3.4 - 0.25 = 4.6

Therefore, the absolute value of х is equal to 4.6.
