Option D:
The solution to the equation is y = 27.
Solution:
Given equation:
To solve this equation:
Multiply by 3 on both sides of the equation.
3 in the numerator and denominator get canceled.
y = 9 × 3
y = 27
The solution to the equation is y = 27.
Option D is the correct answer.
Answer:
The measure of one angle of a regular convex 20-gon is 162°
Step-by-step explanation:
* Lets explain how to solve the problem
- A convex polygon is a polygon with all the measures of its interior
angles less than 180°
- In any polygon the number of its angles equal the number of its sides
- A regular polygon is a polygon that is all angles are equal in measure
and all sides are equal in length
- The rule of the measure of an angle of a regular polygon is
, where m is the measure of each interior
angle in the polygon and n is the numbers of the sides or the angles
of the polygon
* Lets solve the problem
- The polygon is convex polygon of 20 sides (20 angles)
- The polygon is regular polygon
∵ The number of the sides of the polygon is 20 sides
∴ n = 20
∵ The polygon is regular
∴ All angles are equal in measures
∵ The measure of each angle is
∴
∴
∴
∴ m = 162
∴ The measure of one angle of a regular convex 20-gon is 162°
Answer:
Step-by-step explanation:
=
total dist. driven = dist. Meg drove + dist. Tanner drove
Meg = 112
Tanner = x or how far did Tanner drive?
=
* 112 = x
84 =x so Tanner drove 84 miles
total driven = 112 + 84
total driven = 196 :)
