Answer:
m = - 15
Step-by-step explanation:
Using the rule of exponents
× 
= 
, then
× 
= 
, that is
=
=
Equating exponents gives
m = - 15
$9.47
I just multiplied the total by the refund percentage to get that number. It’s just like finding a tip.
For this case, the first thing we must do is define variables:
x: number of pillowcases
y: number of sheets
We now write the system of equations:
2x + 5y = 40
x = 2y
Solving the system we have:
x = 8.9
y = 4.4
Answer:
The maximum number of pillowcases she could have purchased is:
x = 8 (spent less than $ 40)
8, 10, 12
A helpful equation:
x+x+1+x+2 = 30
Combine like terms
3x + 3 = 30
Subtract 3 from each side
3x = 27
Divide each side by to isolate x
x = 9
x = 9. However, 9 is not an even number. Let’s subtract 1 from 9 to get the first even number.
The first number is 8. The best two even numbers after 8 are 10 and 12.
8 + 10 + 12 = 30, thus this is the sequence.
Do 13,500 times .012. Take that answer and multiply it by 10. From that answer, subtract it from 13,500. That would be your final answer.
