An inequality is also an algebraic equation. However, instead of '=' sign, it uses either of these: <, >, ≤, ≥. To translate: <span>X differs from 2 by more than 3, that would be:
2 - x > 3
We use the '>' equation because the open area should face the larger value. Solving the equation:
-x > 3 - 2
-x > 1
x > -1</span>
Answer:
x = 18
A = 110
Step-by-step explanation:
Angles A and B are supplementary angles so they add to 180 degrees
A + B = 180
5x+20 + 9x -92 = 180
Combine like terms
14x -72 = 180
Add 72 to each side
14x-72+72 = 180+72
14x = 252
Divide each side by 14
14x/14 = 252/14
x =18
A = 5x+20
= 5*18 +20
=90 +20
= 110
Answer:
Amount left = 2040
Step-by-step explanation:
Given that:
Per year salary = 12,000
Amount spent on transport = 10%
Transport =
= 0.1 * 12000
Transport = 1200
Tax = 5%
Tax = 0.05 * 12000
Tax = 600
Total = 1200 + 600 = 1800
Amount left = 12000 - 1800 = 10200
Food = 80% of remainder
Food = 0.8 * 10200
Food = 8160
Amount left after food = 10200 - 8160 = 2040
Hence,
Amount left = 2040
