Answer:
-80\112 = -5\7
we divided both numbers by 16
Answer:
506.25
Step-by-step explanation:
Month 1: $100
Month 2: 100 times 1.5 = 150
Month 3: 150 times 1.5 = 225
Month 4: 225 times 1.5 = 337.50
Month 5: 337.50 times 1.5 = 506.25
Answer:
28
Step-by-step explanation:
Here is the complete question used in answering this question :
Three-fourths of the boats in the marina are white. 4/7 of the remaining boats are blue , and the rest are red . If there are 9red boats, how many boats are in the marina?
We first have to determine the fraction of the boats that are red
1 - (
+
)
1 - ![\frac{21 + 16}{28}](https://tex.z-dn.net/?f=%5Cfrac%7B21%20%2B%2016%7D%7B28%7D)
1 - ![\frac{37}{28}](https://tex.z-dn.net/?f=%5Cfrac%7B37%7D%7B28%7D)
1 - 1![\frac{9}{28}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B28%7D)
= 9/28
so, 9/28 of the boats are red
let b represent the total number of boats
9/28 x b = 9
to find b, divide both sides of the equation by 28/9
b = 28
Answer:-3/7
Step-by-step explanation:
I'm 99% sure that the properties only apply to + and X
For this case we must find the value of the following expression:
![4a ^ 2b-c](https://tex.z-dn.net/?f=4a%20%5E%202b-c)
When:
![a = 5\\b = 4\\c = 6](https://tex.z-dn.net/?f=a%20%3D%205%5C%5Cb%20%3D%204%5C%5Cc%20%3D%206)
Substituting the given values we have:
![4 (5) ^ 2 * 4-6 =\\4 (25) (4) -6=\\400-6 =\\394](https://tex.z-dn.net/?f=4%20%285%29%20%5E%202%20%2A%204-6%20%3D%5C%5C4%20%2825%29%20%284%29%20-6%3D%5C%5C400-6%20%3D%5C%5C394)
Finally, the value of the expression is 394.
Answer:
The value of the expression is 394.
