Answer:
x = 0.1, y = 0.075
Step-by-step explanation:
Given the 2 equations
27x + 24y = 4.5 → (1)
1.5x + y = 0.225 → (2)
Multiplying (2) by - 24 and adding to (1) will eliminate the y- term
- 36x - 24y = - 5.4 → (3)
Add (1) and (3) term by term to eliminate y
- 9x = - 0.9 ( divide both sides by - 9 )
x = 0.1
Substitute x = 0.1 into either of the 2 equations and solve for y
Substituting into (2)
1.5(0.1) + y = 0.225
0.15 + y = 0.225 ( subtract 0.15 from both sides )
y = 0.075

Step-by-step explanation:
David received 250 votes
Shari received 400 votes
1,000 - 250=750
750 - 400 = 350

Answer:
2
Step-by-step explanation:
A rational number is a number that can be represented as a fraction.
Numbers
are irrational numbers (they cannot be represented as a fraction).
Number 2 is a rational number (this is the natural number and every natural number is a rational number)
Answer:
x = 18.
Step-by-step explanation:
The 2 amgles are adjacent so add up to 180 degrees so we have:
x^2 - 11x + 3x = 180
x^2 - 8x - 180 = 0
(x -18)(x + 10) = 0
x = -10, 18.
x = -10 cannot be correct because that would make the 3x angle = -30.
