Answer:
Option D is the correct answer.
Step-by-step explanation:
The equations are:
5x - 3y = -11 Eqn 1
2x - 6y = -14 Eqn 2
We have to find the value of y so we will eliminate x.
Multiplying Eqn 1 by 2
2(5x-3y=-11)
10x-6y=-22 Eqn 3
Multiplying Eqn 2 by 5
5(2x-6y=-14)
10x-30y=-70 Eqn 4
Subtracting Eqn 4 from Eqn 3
(10x-6y)-(10x-30y)= -22-(-70)
10x-6y-10x+30y = -22 + 70
24y = 48
Therefore,
Option D is the correct answer.
Answer: 14.83 inches
Explanation:
h² + 6² = 16²
h² = 16² - 6²
h² = 220
h = 14.83
The answer is C
I did this test yesterday
1. The percentage of people surveyed in East Harlem is 58.5%
2. The percentage of people surveyed in Upper East Side is 41.5%
From the question given above, the following data were obtained:
- People surveyed in East Harlem = 183
- People surveyed in Upper East Side = 130
- Total people surveyed = 313
1. Determination of the percentage of people surveyed in East Harlem.
- People surveyed in East Harlem = 183
- Total people surveyed = 313
- Percentage of East Harlem =?
Percentage of East Harlem = (people surveyed in East Harlem / Total) × 100
Percentage of East Harlem = (183/313) × 100
Percentage of East Harlem = 58.5%
2. Determination of the percentage of people surveyed in Upper East Side.
- Percentage of East Harlem = 58.5%
- Percentage of Upper East Side =?
Percentage of Upper East Side = (Total percentage) – (Percentage of East Harlem)
Percentage of Upper East Side = 100 – 58.5
Percentage of Upper East Side = 41.5%
