4x + 3 = -5x - 7 Add 5x to both sides.
4x + 3 + 5x = -5x - 7 + 5x
9x + 3 = -7 Subtract 3 from both sides.
9x + 3 - 3 = -7 - 3
9x = -10 Divide both sides by 9
9x / 9 = -10 / 9
Your answer can either be 1.11111... or it would be x = -10/9

Answer:
x + 20° = 35.56°
3x + 10° = 56.68°
5x + 10° = 87.8°
Step-by-step explanation:
Assume;
Given measures are angle of a triangle
x + 20°
3x + 10°
5x + 10°
Find:
Value of each angle
Computation:
We know that, sum of all interior angle in a triangle is 180°
So,
We say that
x + 20° + 3x + 10° + 5x + 10° = 180°
9x + 40° = 180°
9x = 140°
x = 15.56°
So,
x + 20° = 15.56 + 20 = 35.56°
3x + 10° = 3(15.56) + 10 = 56.68°
5x + 10° = 5(15.56) + 10 = 87.8°
The tabular method is called: cross-tabulation.
<h3>What is Cross-Tabulation?</h3>
- Cross-tabulation, which is also called contingency table or shorten as cross-tab, can be described as a tool in statistics used in analyzing categorical data that involves mutually exclusive values.
- Cross-tabulation is used in analyzing the relationship within a data having two variables, where such relationship are not evident enough.
Therefore, the tabular method is called: cross-tabulation.
