Answer:
252
Explanation:
An equation to represent the situation is:
17.5% * 1440
convert 17.5% into a decimal:
0.175
and then solve:
0.175 * 1440 = 252
The solution is x=3 and y=4
Step-by-step explanation:
Given
As the coefficients of y in both equations are same i.e. 4 with already different signs, we can simply add the equations
So,
Adding Eqn 1 and Eqn 2
Dividing both sides by 27
Putting x=3 in eqn 1
Dividing both sides by 4
Hence,
The solution is x=3 and y=4

Answer:
Answer is given in the pictures
Step-by-step explanation:
Refer the figure given to see the plots
Answer:
The answer is:
morning: 0c
afternoon: -5c
night: 3c
Step-by-step explanation:
Given that night temperature is 3c
and night temperature was 8c higher than the afternoon temperature
so 3c-8c = -5c
afternoon temperature was 5c lower than the morning temperature
so -5c +5c = 0c
