on a farm, 4 1/2 out of every 15 acres of land are used to grow crops. Wheat is grown on 5/8 of the land used to grow crops. What percentage of the total area of the land on the farm is used to grow wheat?
Answers
4.5 + 4 1/2 so for the first part it is a fraction 4.5/15 you then multiply this to 5/8 and get 225/120 which you can then simplify to 3/16 then you work out 3 divided by 16 and get 0.1875 and multiply this decimal by 100 to get the percentage, 18.75%.
Hope this helped, but check with other people (I'm not very good at maths)!

Final answer:
By manipulating and then adding the given system of equations, we can eliminate the variable 'y', resulting in the equation 7x = 35.
Explanation:
To eliminate the variable y in the given system of equations, we need to manipulate the equations to cancel out the y term. The system of equations is:
x + y = 2
3x - 4y = 27
We can accomplish y-elimination by first multiplying the first equation by 4 to match the coefficient in front of y in the second equation. The equations now are:
4x + 4y = 8
3x - 4y = 27
Now, we can add the two equations together, effectively eliminating the y-variable:
4x + 3x = 8 + 27
7x = 35

Answer:
C
Step-by-step explanation:
x + y = 2
Subtract x from both sides;
y = -x + 2
3x - 4y = 27
Substitute y;
3x - 4(-x + 2) = 27
Distribute;
3x + 4x - 8 = 27
7x - 8 = 27
Add 8 to both sides;
7x = 35
Divide both sides by 7;
x = 5

Answer:
The answer will be 12.5%
This is because you divided it by the number of possibilities (which in this case is 2) then divide by the number of times (which is 3).
100 divided by 2 x 6 = 12.5%

y=ax²-bx+c
The vertex is: (-b/2a, f(-b/2a)
In this case:
y=x²-20x+15
-b/2a=20/2=10
f(10)=10²-20(10)+15=100-200+15=-85
Answer: The vertex is (10,-85)
Given a vertex (h,k), the vertex form is :
y=a(x-h)²+k
In this case:
(10,-85)
a=1
y=(x-10)²-85
Answer: y=(x-10)²-85

Answer: 0.07 cups/cookie
Step-by-step explanation:
The Constant of proportionality is the measure by which the number of cookies made, y increases to the number of cups of flour used, x.
If 3.5 cups of flour makes 48 cookies then how many cookies does 1 cup make;
= 3.5/48
= 0.07 cups/cookie
