<h3>
Answer: Choice D. 8:9</h3>
Work Shown:
16 boys: 18 girls
16:18
16/2:18/2
8:9
I divided both parts of the ratio by the GCF 2 in order to reduce from 16:18 to 8:9. For every 8 boys there are 9 girls.
Answer: It is a quicker way to solve the problem.
The answer is 6. 480 divided by 80 gives you the answer 6.
Answer:
6x² + 5x - 6
Step-by-step explanation:
Given
(2x + 3)(3x - 2)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(3x - 2) + 3(3x - 2) ← distribute both parenthesis
= 6x² - 4x + 9x - 6 ← collect like terms
= 6x² + 5x - 6
Answer:
The value of x is 67
Step-by-step explanation:
- <em>If </em><em>two adjacent angles formed a line</em><em>, then they called </em><em>a pair of linear angles</em>
- <em>The </em><em>measure</em><em> of the pair of linear angles is </em><em>180°</em>
In the given figure
∵ One side of the triangle is extended to form an exterior angle of 113°
∵ The angle of 113° and the angle of x° are adjacent angles
∵ They formed a line (the side is extended)
→ That means they formed a pair of linear angles
∴ The angle of 113° and the angle of x° formed a pair of linear angles
∵ The measure of the pair of linear angles = 180°
∴ 113° + x° = 180
→ Subtract 113 from both sides
∵ 113 - 113 + x = 180 - 113
∴ x = 67
∴ The value of x is 67
