Answer:
Step-by-step explanation:
- To know the value that y takes according to the inequation
, we must do some algebra. - First of all, we divide both terms by (-3), wich would change the direction of the inequality, as follow:
(at this point you should remember that dividing or multiplying an inequation by anegative number changes the direction of the inequality).. - This means that
. Then,we just have to add both sides 4, which yields 
. - Then
, which means that, if we divide both sides by 5, we obtain the value of y: (in this case, the direction of inequality does not change because 5 is possitive).
Power of a power as applied to exponents is the following:
The power of a power is the product of the exponents, or
(x^a)^b = x^(ab)
For example
(5^2)^3=5^(2*3)=5^6=15625
Answer: n=37
Step-by-step explanation:
0.05n+0.10x2n=9.25
0.25n=9.25
n=9.25/0.25
n=37
Given:
grapes = 2 1/2 pounds
apples = 1 1/4 times as many pounds as grapes.
For easier computation, let us convert these fractions into numbers with decimal places.
2 1/2 pounds = 2.50 pounds
1 1/4 times = 1.25
Apples = 2.50 pounds * 1.25 = 3.125 pounds of apples.
Or we still use fractions. We need to convert the mixed fractions into improper fractions.
2 1/2 = 5/2
1 1/4 = 5/4
5/2 * 5/4 = 5*5 / 2*4 = 25/8 is simplified to 3 1/8 pounds
