Answer:
The total population of the school is 300 students.
Step-by-step explanation:
Considering, we are working with percentage we can use the equation:
y = %x.
To fill in the equation you can use what you already know, 60% = 180
180 = 0.60x
To solve this, you can then divide both sides of the equation by 0.60. This will then give you your answer, 300 = x.
For checking, you can do 180 = 0.60(300) which will result in 180 = 180.
Terms: 24, 8x, 10(2x)
constants: 24
coefficients: 8, 10, 2
Answer: 180

Answer:
Average rate of change = 2
Step-by-step explanation:
Formula to get the rate of change of a function between x = b and x = a is,
Rate of change = 
We have to calculate the average rate of change between x = -2 and x = 0
From the graph attached,
At x = -2,
f(-2) = 0
At x = 0,
f(0) = 4
Therefore, average rate of change = 
= 
= 2
Average rate of change of the given function between x = -2 and x = 0 is 2.
Adding them up, we have 1/2+3/20+2/5+4/5. We can do a bit of guess and checking to see that 2, 5, and 20 go into 20. 20/2=10 and 20/5=4, so we multiply 1/2 by 10/10 and 2/5 and 4/5 by 4/4 to get 10/20+3/20+8/20+16/20= 37/20
