Answer:
(x,y) = (3, 1/2)
Step-by-step explanation:
This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations..
To solve this, add the equations;
x + 2x + 2y - 2y = 4 + 5
3x = 9
x = 3
substitute the value of x into the first equation,
3 + 2y = 4
2y = 4 -3
2y = 1
y = 1/2
Answer:
17%
Step-by-step explanation:
When finding a percentage you simply move the decimal point to the right two times.
Before you do that you have to round.
0.1709
Since rounding will only cause the 0 to turn into a 1 it's not worth it.
So we know that we have to move the decimal point twice:
017.09
Now the number in front of the decimal point is 17.
Our answer is 17%

Answer:
Length of string = 30.52 m (Approx)
Step-by-step explanation:
Given:
Angle of elevation = 55°
Height of kite = 25 m
Find:
Length of string
Computation:
Sin 55 = Height of kite / Length of string
0.8191 = 25 / Length of string
Length of string = 25 / 0.8191
Length of string = 30.52 m (Approx)
Answer:
Step-by-step explanation:
If we divide 8 by 10, we get 8/10, which reduces to 4/5 or 0.8. Carter misplaced his decimal point.
