Step-by-step explanation:
DG is the total measurement of the line. M is a point inbetween D & G
2x + x - 2 = 7
Simplify. Combine likke terms
(2x + x) - 2 = 7
3x - 2 = 7
Isolate the x. First, add 2 to both sides
3x - 2 (+2) = 7 (+2)
3x = 9
Isolate the x. Divide 3 from both sides
(3x)/3 = (9)/3
x = 9/3
x = 3

3 is your answer for x

Answer:
a < 42
Step-by-step explanation:
Question : 4a + 9a - 6a < 42
Answer :
4a + 9a - 6a < 42
Combine like terms.
13a - 6a < 42
7a < 42
Divide both sides by 7.
a < 42
Hope this helps you :-)

Area of a circle = pi x r^2
Area of circle = 150,000/ 1578 = 95.06 square miles
95.06 = 3.14 x r ^2
Divide both sides by 3.14
R^2 = 30.27
Find the square root:
R = sqrt(30.27)
R = 5.5
The radius is c) 5.5 miles
Answer:
It's a valid sample because the first five people were selected to participate.
Step-by-step explanation:
True because random people who saw the advertisement responded. By chance, not every person who saw the advertisement answered, therefore it was random, but it would be more random if he decided to reject the second, fourth, sixth, and eighth person, and only the first, third, fifth, seventh, and ninth were chosen.
Answer:
y = 8 degrees
Step-by-step explanation:
128 + 7y - 4 = 180
7y - 4 = 52
7y + 56
y = 8
