Answer:
Step-by-step explanation:
For two angles x and y to be supplementary, the sum of the angles must be 180°
x+y = 180
x = 180-y... 1
If the measure of the angle is five times greater than its supplement this is expressed as:
x = 5y…. 2
Substitute equation 2 into 1
5y = 180-y
5y+y = 180
6y = 180
y = 30°
Hence the measure of the supplement is x = 5y
x = 5(30)
x = 150°
Divide the number satisfied by total people surveyed then multiply by 100 for the percent.
960/2400 = 0.4
0.4 x 100 = 40%
The answer is 40%
Distance travelled by train in x minutes is equal to 60fx feet as per given constant rate of f feet per second.
As given in the question,
Train travelled at a constant rate f feet per second
Let d be the distance travelled by train in x minutes
1 second =f feet
60 seconds = (60f) feet
1 minute = (60f) feet
x minutes = (60fx)feet
Therefore ,distance travelled by train in x minutes is equal to 60fx feet
as per given constant rate of f feet per second.

Answer:
(c) 5x and 3x, and 4 and 1
Step-by-step explanation:
Like terms have the same variable(s) to the same power(s).
The terms of this expression are ...
- x^3: variable x, power 3
- 5x: variable x, power 1
- -3x: variable x, power 1
- 3y: variable y, power 1
- 4: no variable
- -1: no variable
The like terms are {5x, -3x}, which have the x-variable to the first power, and {4, -1}, which have no variable.
