Answer:
x + y = 2
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y + 3 = - (x - 5) ← distribute
y + 3 = - x + 5 ( subtract 3 from both sides )
y = - x + 2 ( add x to both sides )
x + y = 2 ← in standard form
The average score of all the students in both classes is 84.
<h3>How to calculate the average?</h3>
The class with 30 students had an average score of 80 on a test. The total score will be:
= 30 × 80
= 2400
A class with 20 students had an average score of 90 on the same test. The total score will be:
= 20 × 90
= 1800
Total scores = 2400 + 1800 = 4200
Number of students = 20 + 30 = 50
The average score will be:
= Total score / Total students
= 4200 / 50
= 84

Answer:
6 meters
Step-by-step explanation:
<u>Intersecting Chord Theorem:</u> When two chords intersect each other inside a circle, the products of their segments are equal.
One chord is divided into two segments with lengths of 15 m and 2 m.
Anothe chord is divided into two segments with measures of 5 m and n m.
Therefore,
21.5 • 8.50 not that hard just multiply the numbers
7 because 4+2=6 and 1/2+1/2=1 so 6+1=7
