Step-by-step explanation:
Given the 2 equations
2x - 3y = - 2 → (1)
4x + y = 24 → (2)
Multiplying (1) by - 2 and adding to (2) gives
- 4x + 6y = 4 → (3)
Add (2) and (3) term by term
(4x - 4x) + (y + 6y) = (24 + 4), that is
7y = 28 ( divide both sides by 7 )
y = 4
Substitute y = 4 into either of the 2 equations
Substituting y = 4 into (2)
4x + 4 = 24 ( subtract 4 from both sides )
4x = 20 ( divide both sides by 4 )
x = 5
Thus the answers x = 5 and y = 4 are the same as her first method
Answer:
Option C 
Step-by-step explanation:
Given : Astronomers measure large distances in light years. One light-year is the distance that light can travel in one year or approximately 5,880,000,000,000 miles.
Suppose a star is 14.4 light years from earth.
To find : How many miles away a star is from earth?
Solution :
In 1 light-year the distance a light can travel is = 5,880,000,000,000 miles.
or = 
miles
In 14.4 lights year the distance is 
or
Therefore, Option C is correct -

8. idk
9. hexagonal prism <span />
Answer:
5x − 4 = 3x + 8
5x - 4 <em>+ 4</em> = 3x + 8 <em>+ 4</em>
5x = 3x + 12
5x <em>- 3x</em> = 3x + 12 <em>- 3x</em>
2x = 12
2x <em>/ 2</em> = 12 <em>/ 2</em>
x = 6
Answer:
The equation of a right triangle is given by a2 + b2 = c2, where either a or b is the height and base of the triangle and c is the hypotenuse. Using the Pythagorean Theorem, finding the missing side of a triangle is pretty simple and easy. The two special right triangles include: 45°; 45°; 90° Triangle.
