An exponent signifies repeated multiplication.
the factor x is repeated 3 times
Exponents can be added and subtracted to express the effects of multiplication and division.
The addition and subtraction of exponents works the same even when there are more denominator factors than numerator factors.
That is, a negative numerator exponent is the same as a positive denominator exponent and vice versa. You can move a factor with an exponent from denominator to numerator and change the sign of the exponent, and vice versa.
Your expression has 3 in the denominator with a negative exponent. It can be moved to the numerator and the exponent changed to positive:
X-1= 5x+3x-8
Combine like terms
x-1= 8x-8
Our goal is to isolate x by cancelling out other numbers.
Subtract x from both sides
x-1-x= 8x-x-8
-1= 7x-8
Add 8 to both sides
7=7x
Divide both sides by 7
1=x
Final answer: x=1
By using the formula:
<span>FV = PV*(1+r/n)^(n*t)
</span><span>FV = 3000
PV = 100
r = 0.02
n = 12
t = ?</span>
Substituting the values of the variables, I got <span>a. 170.202 years. Hope that really helps. </span>
The unit rate is $2.75
If you divide the cost by Movies/week you would always get $2.75
For example:
11÷4=2.75
13.75÷5=2.75
19.25÷7=2.75
22÷8=2.75
Hope this helps you :))
Angelica would have painted the bedroom in 20 hours if every hour she painted 1/20. But she doesn't paint 1/20 of a room per hour but rather 30 minutes. That means it will take her 10 hours to paint the whole room.
Hope this helps.
