(3)(6)
6+6+6
for represent the situation
Step-by-step explanation:
the dining room has 3 tables
and at each table there are 6 chairs so multiplication is the operation to use to find the total
therefore the other operations do not represent the situation
but 6+6+6 represents because it is also equal to 18
Answer:
17 boys and 11 girls
Step-by-step explanation:
Create a system of equations where b is the number of boys and g is the number of girls:
b + g = 28
b = g + 6
Solve by substitution, by substituting the second equation into the first one:
b + g = 28
(g + 6) + g = 28
2g + 6 = 28
2g = 22
g = 11
So, there are 11 girls.
Since there are 6 more boys than girls, there are 17 boys.
So, there are 17 boys and 11 girls in the class.

Given:
The exponential function is:

To find:
The percentage rate of increase or decrease.
Solution:
The general exponential function is:
...(i)
Where, a is the initial value, |r| is the growth rate in decimals if r>0 and |r| is the decay rate in decimal if r<0.
The exponential function is:

It can be written as:

...(ii)
On comparing (i) and (ii), we get

Since r is negative, therefore the given function is a decreasing or decay function.
Now,
So, the rate of decrease is 0.06. Multiply this number by 100 to get the percentage.

Therefore, the rate of decrease is 6%.
