Answer:
exact form: 23/15
decimal form: 1.5333333333 (infinitely or add a little line on top of the 3)
mixed number form: 1 8/15
Step-by-step explanation:
Answer:
(-3, -4).
Step-by-step explanation:
-4x + y = 8
x - 5y = 17 Multiply this by 4:
4x - 20y = 68 Add this to the first equation:
-19y = 76
y = 76/-19
y = -4.
Plug this into the second equation:
x - 5(-4) = 17
x = 17 - 20
x = -3.
CHECK this result in equation 1:
-4(-3) + -4 = 8
12 - 4 = 8
8 = 8 <------ OK.
330 km/hr
Step-by-step explanation:
To find speed of the plane against the headwind;
600 km / 2 hours = 300 km/hr
Speed of plane with the wind in its back;
600 km / 5/3 hours = 600 * 3/5 = 360 km/hr
We can create a simultaneous equation from this data.
Assume the speed on pane in still air is x km/h
Assume the speed of wind is y km/h
Therefore;
x – y = 300
x + y = 360
Solving the simultaneous equation by elimination gives us;
x – y = 300
-
x + y = 360
=
-2y = - 60
y = 30
x = 330
The speed of the plane without wind is;
= 330 km/hr
The wind speed is;
= 30 km/hr

Step-by-step explanation:
- 5+<em>4</em>=9
- 9+<em>5</em><em>=</em>14
- 14+<em>6</em><em>=</em>20
- 20+<em>7</em><em>=</em><u>2</u><u>7</u>
- 27+<em>8</em><em>=</em>35
So The sequence is 5,9,14,20,<u>2</u><u>7</u><u>,</u>35
