Answer:
Betsy uses gold to make the earrings
Step-by-step explanation:
Given:
Amount of gold with Betsy = ten and one half ounces
Amount of gold Betsy used to make earrings = four fifths
To Find:
How much gold is used by Betsy to make earrings = ?
Solution:
Let the quantity of gold used by Betsy to make earring be X
Then
X = four fifths of ten and one half
X =
X =
X =
X=
Reducing the fraction to lower terms and converting into mixed fraction we get,
X=
Answer:
-3y^2 + y + 100
Step-by-step explanation:
Combine like terms.
-3y+4y = 1y or "y"
Add "y" back into the equation.
-3y^2 + y + 100
The equation cannot be simplified any further.
I hope this helped!
Answer:
The value of k is and The value of p is - 23
Step-by-step explanation:
Given equation as :
81 y - 17 = k² y + 6 + p
The equation has real solution ,
Now for real solution the equation have no solution
∵ The equation has no solution the ,
The coefficient of y must be equal
I.e 81 = k²
Or, k =
∴ k =
Again , If the coefficient of y is same then the equation is written as
6 + p = - 17
or, p = - 17 - 6
or, p = - 23
Hence The value of k is and The value of p is - 23 Answer
The equation is y=2x+4.
