3*3*3=9 perhaps?? And then it would be in Surface Area??
(1) -(5y - 2)= -5y+2
(2) -5 (3n + 1)= -15n - 5
(3) too long to do
That is correct because it’s a real high school
Answer:
From 2.5 y to 1.5 y there is a 40 % DECREASE in the value.
Step-by-step explanation:
Here, the initial value = 2.5 y
The final value of 1.5 y
Now,as Final Value < Initial Value
So, there is a DECREASE IN THE VALUE.
Now, decrease in the value = Initial value - Final Value
= 2.5 y = 1.5 y = 1 y
or, there is a decrease of ( 1 y) in the given value.
Now, Percentage decrease in the value is given as:

or, Percentage Decrease = 40%
Hence, from 2.5y to 1.5y there is a 40 % DECREASE in the value.
Answer:
There is no following, we have data of all the people
Step-by-step explanation:
There where Sixty-five salespersons asked and the if we add all the persons that where asked it is the same. So there is no following
Fourteen people answered that they generally sell two cars; 14
nineteen generally sell three cars; 19
twelve generally sell four cars; 12
nine generally sell five cars; 9
eleven generally sell six cars 11
Adding 14+19+12+9+11=65 persons
